The full – also known as a double – is one of the six standard mattress sizes. Although specific dimensions vary by model, most full size mattresses measure 53 to 54 inches wide and 75 inches long. The full falls between a twin XL and a queen, making it a mid-level size.

While wider than a twin or twin XL, full size mattresses are still a bit too narrow for most couples to sleep comfortably. However, the full is ideal for single adult or child sleepers who want extra room to move around in bed. For children who share a room, you can use a twin-over-full or full-over-full bunk bed to save floor space. A full size mattress is also well suited to college students sharing dorm rooms and adults with smaller bedrooms.

Our picks for the best full mattress models sold today are listed below. To make these selections, we drew from verified experiences from full size mattress owners, as well as our own product research and analysis. This guide also discusses common dimensions and prices for full mattresses, pros and cons associated with this size, and important considerations for first-time mattress buyers.

The Best Full Mattresses

Product Details

Nectar

Nectar
Mattress Type:
Foam
Firmness:
Medium Firm (6)
Nectar
Highlights:

Thanks to three layers of contouring memory foam, the Nectar hugs your body closely to cushion the shoulders and hips, align the spine, and alleviate pressure points. The mattress comes with a one-year trial and lifetime warranty.

Who it's best for:
  • Adults and kids who enjoy the deep body contour of a memory foam mattress
  • People who frequently experience pressure points
  • Value seekers

The Nectar is an all-foam mattress constructed with three memory foam layers. These include two comfort layers made of open-cell material that conform closely and respond slowly, creating a deep, pressure-relieving cradle as your body sinks beneath the surface. The third memory foam component is a bit denser, and acts as a transitional layer to prevent you from sagging too deeply. The Nectar also contains a support core made from robust high-density polyfoam. Compared to other all-foam models, the Nectar offers above-average edge support and great overall stability.

Like other memory foam mattresses, this model is very suited to people who constantly feel pressure points in their shoulders, hips, and other sensitive areas. Despite the Nectar’s medium firm feel, the foam layers cushion the body to align the spine for side sleepers. The mattress is also supportive enough to keep back and stomach sleepers on an even plane without sinking too much beneath their heavier areas. The Nectar may also be a good choice if you share your full size mattress with another person. The surface absorbs motion and eliminates nearly all transfer across the surface, and the bed itself does not produce any noise.

The Nectar’s price-point is very affordable for a memory foam bed. The company also offers a 365-night sleep trial and lifetime warranty, both of which are much longer than average. Standard ground shipping is also free for anyone in the contiguous U.S.

Layla Hybrid

Layla Hybrid
Mattress Type:
Hybrid
Firmness:
Medium Soft (4), Firm (7)
Layla Hybrid
Highlights:

The reversible Layla Hybrid offers a medium soft feel on one side and a firm feel on the other. Both comfort layers consist of conforming, copper-infused memory foam, and the support core features zoned coils to ensure strong edge support.

Who it's best for:
  • Adults and children who prefer the responsive and contouring feel of a memory foam hybrid
  • Sleepers whose firmness preferences fluctuate between medium soft and firm
  • Hot sleepers

The Layla Hybrid is a reversible model and both sides of the mattress are constructed with memory foam comfort layers. One sleep surface has a medium soft feel and conforms very closely to the body. You’ll sink quite a bit on this side, creating an ideal feel for many side sleepers and individuals who weigh less than 130 pounds. The opposite side offers a firm feel with minimal contouring and strong support. This surface is better suited to people who weigh more than 230 pounds, back and stomach sleepers, and other individuals who need more reinforcement and stability from their mattress.

The memory foam layers are infused with copper, which has cooling properties and can minimize the buildup of body heat on both surfaces. The shared support core, which contains thick pocketed coils, also generates strong airflow to help the mattress maintain a comfortable temperature. The support core is zoned, as well. Higher-gauge (thinner) coils rest beneath your body to promote a comfortable balance of cradling and support, while lower-gauge (thicker) coils line the perimeter and prevent excessive sinkage when you get on and off the mattress.

The Layla Hybrid is available at a reasonable cost for any memory foam hybrid – let alone a flippable model with two firmness levels. Layla provides free shipping throughout the contiguous U.S., as well. The Layla Hybrid is backed by a 120-night sleep trial and a 10-year warranty.

WinkBed

WinkBed
Mattress Type:
Innerspring
Firmness:
Soft (4), Medium (6), Medium Firm (7-8), Plus (7-8)
WinkBed
Highlights:

The WinkBed luxury hybrid is composed of contouring comfort layers and an exceptionally strong coil system with zoned support to protect the edges. You can choose from four firmness levels that accommodate people with different body types.

Who it's best for:
  • Adults and children who’d rather sleep on a very springy mattress
  • Those seeking a mattress with exceptionally strong support
  • Hot sleepers

The WinkBed is a model that is available in different firmness levels. You can choose a medium soft, medium firm, or firm feel for the standard WinkBed, which is constructed with layers of gel-infused polyfoam and pocketed minicoils over a support core of pocketed coils. The standard WinkBed owes its highly responsive surface to the coil-on-coil design. The coil layers promote strong airflow to keep the mattress cool, as well.

If you weigh more than 230 pounds, then you may want to consider the WinkBed Plus. This firm variation of the standard WinkBed is specifically designed for people in this weight group. Instead of pocketed minicoils, the WinkBed Plus contains layers of gel-infused polyfoam and breathable latex. The latex is divided into firmness zones for enhanced support to your lower back and hips, and light cradling for the head, neck, and legs. The support coils in all versions of the WinkBed are also zoned, with thicker coils reinforcing the perimeter against sinkage and thinner coils beneath your body. This ensures maximum edge support without the mattress feeling too stiff.

The WinkBed’s price-points put the mattresses on par with the average hybrid model. WinkBeds offers free ground shipping within the contiguous U.S., along with White Glove delivery for an added charge. The WinkBed and WinkBed Plus are backed by 120-night sleep trials and non-prorated lifetime warranties.

DreamCloud

DreamCloud
Mattress Type:
Hybrid
Firmness:
Medium Firm (6.5)
DreamCloud
Highlights:

Measuring 15 inches thick, the DreamCloud luxury hybrid is constructed with conforming polyfoam and memory foam comfort layers over a sturdy, responsive pocketed coil base. All buyers receive a one-year sleep trial and lifetime warranty.

Who it's best for:
  • Adults and kids who prefer the gentle contouring and springiness of a memory foam hybrid
  • People who like sleeping on very thick mattresses
  • Hot sleepers

Our final pick is the DreamCloud. This hybrid model features comfort layers of memory foam and gel-infused memory foam, along with a transitional polyfoam layer. The mattress has a medium firm feel, resulting in a moderate yet even body contour that promotes spinal support and pressure relief. The DreamCloud also has a support core of pocketed coils reinforced with high-density base foam. Altogether, the mattress measures 15 inches tall, making it much thicker than the average mattress. Certain types of sleepers – particularly those who weigh more than 230 pounds – tend to have an easier time getting on and off high-profile models because they are not too close to the floor.

The DreamCloud’s thick pocketed coils provide excellent stability and support. Most people will notice very strong reinforcement along the edges when getting on and off the mattress, and the surface should be easy to move across without sinking too much. Temperature control is another major strength. The coils promote steady airflow to keep the mattress cool, and the DreamCloud’s cover is crafted from a breathable fabric blend that includes moisture-wicking cashmere.

This model has a very reasonable price given its luxurious components and sophisticated design. The DreamCloud is backed by a generous 365-night sleep trial and a lifetime warranty with no prorated period. Shipping is free for all customers in the contiguous U.S.

Tuft & Needle Hybrid Mattress

Tuft & Needle Hybrid Mattress
Mattress Type:
Hybrid
Firmness:
Medium (5)
Tuft & Needle Hybrid Mattress
Highlights:

The budget-friendly Tuft & Needle Hybrid combines adaptive, graphite-infused polyfoam and sturdy pocketed coils with enhanced reinforcement along the perimeter. Steady airflow in the coils ensures consistent breathability.

Who it's best for:
  • Adults and children who like the responsive feel of a polyfoam hybrid
  • Sleepers who weigh up to 230 pounds
  • People who tend to sleep hot

The Tuft & Needle Hybrid is constructed with a comfort layer of adaptive, open-cell polyfoam infused with graphite and other cooling materials. The surface has a medium feel and the foam conforms more closely than the polyfoam layers found in other competing hybrids. This allows side sleepers and people weighing less than 130 pounds to feel comfortable. The Tuft & Needle Hybrid also contains a minicoil comfort layer, along with a pocketed coil support core. These two layers create a very responsive and supportive feel that makes the mattress more comfortable for back and stomach sleepers up to 230 pounds.

Like other hybrids, this model also provides a very balanced feel. The adaptive foam absorbs movement from sleepers to mostly eliminate motion transfer across the surface, and the coil layers are relatively silent when bearing weight. As a result, the mattress is a good option for people who don’t mind sharing a full size with their partner and wake up easily. The coil-on-coil construction also gives the mattress good springiness, making it suitable for couples who enjoy responsive beds for sex. Edge support is very strong, as well. You shouldn’t feel much sinkage when getting on and off the Tuft & Needle Hybrid, provided you weigh 230 pounds or less.

This mattress has a price-point that is on par (if not slightly lower) than that of the average hybrid model. Tuft & Needle also ships the hybrid for free anywhere in the contiguous U.S. You’ll receive a 100-night sleep trial and 10-year warranty, as well.

Saatva

Saatva
Mattress Type:
Innerspring
Firmness:
Soft (2-3), Medium Firm (6), Firm (7-8)
Saatva
Highlights:

The robust and responsive Saatva innerspring is a coil-on-coil innerspring available in two profiles and three firmness levels. Free White Glove delivery is available for all customers.

Who it's best for:
  • Adults and children who enjoy the responsive feel of a coil-on-coil mattress
  • Those who prefer sleeping on high-profile beds
  • Hot sleepers

Next up is the Saatva, also known as the Saatva Classic. This flagship mattress is constructed with a polyfoam-padded Euro-top cover, followed by polyfoam and memory foam comfort layers and a transitional layer of foam-padded minicoils. The support core consists of bonnell coils made from tempered steel. While the Saatva is considered a hybrid, its coil-on-coil design creates an exceptionally bouncy surface akin to that of a traditional innerspring. Two coil layers also ensure strong internal airflow and excellent temperature control.

You can choose from three firmness levels for your Saatva. The soft option provides the closest conforming, though you’ll still feel strong support and shouldn’t sink too deeply. The medium firm and firm options offer little to no conforming, along with very strong reinforcement and excellent edge support. All three firmness options provide great responsiveness for sex, and the lack of sinkage makes the mattress easy to move across when getting in and out of bed. Saatva offers 11.5-inch and 14.5-inch profiles for the mattress, as well.

The mattress has a reasonable price-point compared to other premium hybrids and innersprings. Saatva is one of the only mattress brands to offer free White Glove delivery for all orders. Most competing companies charge at least $100 for this service, which includes scheduled delivery date and time, full assembly in a room of your choice, and old mattress removal. The mattress is backed by a 180-night sleep trial and a non-prorated 15-year warranty, as well.

Leesa Hybrid

Leesa Hybrid
Mattress Type:
Hybrid
Firmness:
Medium Firm (6)
Leesa Hybrid
Highlights:

The medium firm Leesa Hybrid boasts responsive yet conforming mixed-foam comfort layers and a thick pocketed coil support core that provides sturdy edge support. Ideal for many back and stomach sleepers.

Who it's best for:
  • Adults and kids who like the contouring, supportive feel of a mixed-foam hybrid
  • People who weigh up to 230 pounds
  • Hot sleepers

The Leesa Hybrid, our next pick, is constructed with polyfoam and memory foam comfort layers, along with a polyfoam transitional layer. These three mixed-foam layers create a very balanced feel. The memory foam ensures even contouring, while the polyfoam layers give the surface a light bounce. The result is a conforming and pressure-relieving mattress that won’t sink too deeply. A support core of pocketed coils reinforces the mattress for added stability and responsiveness.

The mattress has a medium firm feel. While people who weigh more than 230 pounds may find the Leesa Hybrid comfortable, we think it is best suited to those who weigh up to 230 pounds. Side sleepers receive comfortable cushioning for their shoulders and hips, which can improve spinal alignment and reduce pressure throughout the body. The Leesa Hybrid’s strong coils also ensures even support and minimal sagging for back and stomach sleepers in this weight group. And while mattress foam often absorbs body heat and sleeps somewhat warm, the Leesa Hybrid’s coil layer generates consistent airflow to help the mattress – and you – stay cool.

The Leesa Hybrid’s full size price-point is comparable to that of the average hybrid mattress. Unlike most competing brands, Leesa offers free ground shipping to all 50 states. The hybrid is backed by a 100-night sleep trial and a 10-year warranty. For each purchase, Leesa donates a mattress to a needy child as part of the One Good Bed Promise program.

How to Choose a Full Mattress

The full (or double) is a popular mid-level mattress size for single sleepers. It offers more width than a twin or twin XL, creating plenty of space for people who toss and turn or frequently shift positions, but the full conserves more space than a queen, king, or California king.

As with mattresses of any other size, selecting the right full size model requires a bit of research on your part. Read on to learn about different factors to look for when choosing your full mattress.

What to Look for in a Mattress

Brand and product research is essential for finding the best full size mattress. Every individual model offers a unique sleep experience, and is designed for people with certain body types, sleep positions, and firmness preferences. Keep that in mind as you visit mattress websites and read product descriptions. Some brands have the tendency to infuse misleading and hyperbolic descriptions into their onsite advertising. Be especially wary of claims that a mattress is suited for any type of sleeper, that it will last forever.

Instead, we recommend using these attributes to guide your full size mattress search.

  • Price: The price of a full size mattress will depend on its materials and design, as well as the brand selling the bed. That said, you should be able to find a high-quality full mattress for $1,500 or less. Be sure to factor in shipping costs if you reside in Alaska or Hawaii, as well as return fees if they apply.
  • Sleeping Position: Your sleep position will most likely dictate which mattresses feel more and less comfortable. Side sleepers typically need a softer feel for adequate cushioning, even spinal alignment, and pressure relief. For back and stomach sleepers, a balance of contouring and support is needed to keep their bodies on an even plane.
  • Mattress Type: Mattresses sold today fall into five general categories, each associated with distinct characteristics. All-foam mattresses offer close body-conforming and slow response, while all-latex beds feel a bit springier as they contour. A traditional innerspring will feel very responsive, whereas hybrids offer the bounciness of coils and the conforming of thick comfort layers. If you want a mattress that offers adjustable firmness, then an airbed may be the best option.
  • Contouring: Some mattresses conform very closely to the body while others feel very stiff and conform very little. The best full mattresses for contouring will promote even support to reinforce your torso and hips while cradling the head, neck, and legs. All-foam, all-latex, and hybrid mattresses generally provide the best contouring.
  • Quality Materials: The materials used to build your mattress can affect a number of factors, including durability, temperature neutrality, pressure relief, and edge support. High-quality mattress components associated with strong overall performance include dense memory foam, organic latex, and sturdy coils divided into thickness zones.
  • Firmness Level: We use a 1-10 scale to evaluate mattress firmness, with 1 being the softest possible feel and 10 the firmest. Most beds sold today fall between 2 and 8. You may prefer a softer mattress (1-3) if you want a deep body contour and a bit of sinking. A firmer mattress (7-10) may be more suitable if you want less conforming and stronger support. For many people, a mid-level firmness (4-6) offers the most comfortable and balanced feel.
  • Pressure Relief: Many people experience pressure points in their shoulders, lower back, and hips. A mattress that does not support these areas and promote spinal alignment can make the issue worse. Whether you sleep on your side, back, or stomach, be sure to choose a mattress that will keep your body and spine on an even plane.
  • Edge Support: Mattress with weak edge support will sink quite a bit when you get on and off the bed. You may also feel less secure lying near the perimeter, leaving you confined to the center. Coils generally provide the best edge support, whereas foam and latex layers are more prone to deep sinkage and less perimeter stability.
  • Temperature Regulation: If you sleep hot, you may want to select a mattress made with components that promote breathability and temperature control. These include ventilated foam or latex comfort layers, coils that promote airflow, and covers made from natural fibers. Dense foam tends to sleep warmer than any other mattress material.
  • Noise: Most all-foam and all-latex mattresses are completely silent. These models will be best suited to people who easily wake up due to noise. Other beds tend to be louder due to their internal components, such as the coils found in innersprings and hybrids, or the whirring air chambers used to adjust the firmness levels in airbeds.

Who Is Best Suited to a Full Mattress?

Full size mattresses usually measure 53 to 54 inches wide and 75 inches long. Some brands use “double” for this size instead, but the terms are interchangeable. Fulls are about 14 to 15 inches wider than a standard twin or twin XL. While still a little too narrow for most couples, this extra width ensures ample room for solo sleepers. However, it’s important to note that anyone who stands taller than 6 feet 2 inches (74 inches) may not have enough room for their legs and feet on a full size bed.

Toddlers and Kids: Full size mattresses are a good option for children and toddlers, especially if your kiddo wants a larger bed to themselves. Fulls are a bit pricier than twin and twin XL models, but costs are usually reasonable, and they take up less floor space than queens, kings, and California kings. Select twin-over-full and full-over-full bunk beds are available, as well.
Teenagers: A full size mattress can be ideal for teenagers, especially if they tend to move around in their sleep. Bedroom dimensions may be an issue, though, since teenagers’ rooms tend to be on the smaller side. Typically, teens need a firmer mattress than toddlers and children because they weigh more and require added support.
College Students: While a full mattress may not be ideal for exceptionally small dorm rooms, this size should work in a decently sized suite or apartment bedroom. Students who stand taller than 6 feet 2 inches may want to consider a twin XL for the added legroom and extra floor space.
Single Adults: If you normally sleep alone, then a full size mattress should provide adequate space without taking up too much room. Many people find the full sleeps a single sleeper and a dog or cat rather comfortably, but adding a second person into the equation may feel too cramped for all involved.
Those with Guest Rooms: Like the twin and twin XL, a full size mattress is a good option for guest bedrooms because it takes up a minimal amount of floor space and shouldn’t cost too much. However, the mattress will probably only sleep comfortably for one overnight guest.

Full vs. Queen

A standard full size mattress measures 53 to 54 inches wide and 75 inches long. Its width is best suited to single sleepers. Couples who don’t mind getting cozy may feel comfortable, but most will find a full size too narrow. The length of a full size mattress is optimal for people who stand 6 feet 2 inches or shorter.

A standard queen measures 60 inches wide and 80 inches long. Due to its wider and longer dimensions, a queen can comfortably sleep two people, as well as individuals who stand 6 feet 7 inches or shorter. However, queens take up more floor space than fulls, and – in most cases – also have higher price-points.

Pros and Cons of a Full Mattress

Every mattress size carries its own list of pros and cons. Some notable benefits and drawbacks of full size mattresses are outlined below.

Pros Cons
  • Wide enough to comfortably sleep one person (and possibly a pet or two)
  • Long enough to accommodate anyone under 6 feet 3 inches tall
  • Mid-level price-point that’s often lower than queens, kings, and California kings
  • Kid-friendly and compatible with some bunk beds
  • Available for the vast majority of mattresses sold today
  • Too narrow for most couples and co-sleepers to sleep comfortably
  • Not long enough for people who stand 6 feet 3 inches or taller
  • Usually more expensive than twin and twin XL models
  • Takes up too much space for some bedrooms, dorm rooms, and guest rooms

What Type of Mattress Is Best for a Full?

Mattresses sold today fall into one of five general categories based on material content and design: hybrid, innerspring, latex, airbed, or memory foam. Each mattress type excels in some areas and underperforms in others. The trick to finding the best double mattress is determining which attributes are most important to you. Check out our detailed look at each mattress type below for more details.

Hybrid

Definition: A hybrid is a specialized type of coil mattress designed to provide a balance of contouring and support. These models usually have comfort layers of polyfoam, memory foam, latex, and other conforming materials. The support core almost always consists of individually pocketed coils.

Pressure Relief with Added Support: Due to their all-encompassing designs, hybrids offer consistent performance in a wide range of areas. Their thick comfort layers conform and cushion the body to align the spine and reduce pressure and back pain. Hybrids also sleep reasonably cool thanks to air-circulating coils, and edge support is typically very strong.

Innerspring

Definition: A traditional innerspring is built with thin comfort layers of polyfoam and/or memory foam and a thick support core containing steel coils. As the name implies, these mattresses feel very “springy” on the surface. Innersprings are the most widely sold mattress type among U.S. consumers, as well as the cheapest on average.

Extra Bounce: An innerspring is ideal for anyone who wants a highly responsive mattress. You won’t feel much of a contour due to the thinner comfort layer(s), but innersprings are easy to move across because they don’t sink excessively. Edge support is usually quite strong, as well, so you’ll have an easier time getting in and out of bed.

Latex

Definition: Latex is a material composed from the sap of rubber trees mixed with chemical fillers. When processed into a foam material for mattresses, latex contours a bit but also feels fairly responsive. The material is very durable, as well. You can expect to sleep on a latex mattress for at least eight years until a replacement is needed.

Sink-Free Contouring: While memory foam contours very closely and evenly, a common complaint is that the material sinks too much. Latex offers comparable conforming but its natural responsiveness prevents you from sinking deeply beneath the surface. Additionally, latex is more breathable than foam and won’t absorb or trap as much body heat.

Airbed

Definition: Airbeds are designed with two or more air chambers in their support cores. You can add or release air from any chamber to adjust the firmness in different areas of the sleep surface. Airbeds may also have comfort layers of polyfoam, memory foam, and/or latex. On average, airbeds are the most expensive mattress type.

Exceptional Customization: Many people would rather sleep on a softer mattress one night and a firmer one the next. Airbeds are an ideal choice for these individuals. On high-quality airbeds, you can choose from dozens of firmness levels, and many are designed with dual-firmness options for couples whose preferences differ.

Foam

Definition: An all-foam mattress features comfort layers of polyfoam, memory foam, or a combination of both materials. Most models also contain transitional and support layers made from denser foam material. All-foam beds provide unparalleled body-conforming, allowing you to sink into the surface of the mattress. Like innersprings, these models tend to have below-average price-points.

Targeted Pressure Relief: People who frequently feel pressure points should consider an all-foam mattress. This is particularly true for side sleepers who experience pressure due to irregular spinal alignment. Back sleepers and stomach sleepers also benefit from the contouring of an all-foam mattress, provided the support system is robust enough to keep them on an even plane.

Last Things to Consider with a Full Mattress

Now that we’ve discussed the dimensions and price expectations for a full size mattress, as well as important considerations for mattress buyers, you’re almost ready to go pick out a bed. But before you do, take a gander at these common questions regarding full size models.

Who Will Use the Mattress?

If you’re buying a full size mattress for yourself, you should select a model based on your body weight, sleep position, and general firmness preferences. Keep in mind that most – but not necessarily all – sleepers who weigh less than 130 pounds prefer a softer feel with more conforming, while most people who weigh 230 pounds or more need more support from their mattress.

Finding the best full mattress for kids can be a bit trickier. If you’re buying the mattress for a teenager or child, make sure to include them in the research process. Visiting a mattress store to test out beds with different firmness levels and materials is often the best way to determine proper firmness, whether the bed is for you or someone else.

Is the Mattress for a Bunk Bed?

While they aren’t very common, some bunk beds are compatible with full size mattresses. These include twin-over-full and full-over-full models. If you’re choosing a full size mattress for a bunk bed, make sure to check the bed’s listed weight capacity. This figure includes the sleepers and their mattresses, so heavier full size beds may not be the best option.

Additionally, you should take thickness into account when choosing a bunk bed mattress. Guidelines from the U.S. Consumer Product Safety Commission state that a mattress should be at least 5 inches shorter than the guard rails on top bunks; otherwise, sleepers may be at risk for falling off the bed.

Mattress Warranty and Other Policies

In addition to different mattress models, you should also compare brands for shipping costs, return policies, and warranty coverage.

Online mattress brands usually offer free ground shipping throughout the contiguous U.S., and some also provide free delivery to Alaska, Hawaii, and/or Canada. White Glove delivery, which includes in-home assembly and old mattress removal, typically costs at least $100 extra, but a few brands offer this service for free, as well.

Mattresses sold online almost always come with a sleep trial of 90 nights or longer. In some cases, you’ll need to sleep on the bed for up to 30 nights before you can return or exchange it. Returns are almost always free, but some brands charge fees.

All mattresses come with a warranty, and the vast majority of warranties cover the bed for at least 10 years. For a non-prorated warranty, you won’t pay anything to have a defective mattress repaired or replaced apart from some minor shipping fees. Prorated warranties require you to pay a percentage of the bed’s original sticker price if a defect develops and a replacement is needed.

Common defects covered under a mattress warranty include surface-level sagging and impressions of a certain depth (usually 1.5 inches or less), physical flaws in the mattress assembly that lead to early wear and tear, and manufacturing defects with the cover. Other issues will probably not be covered under warranty.
