A king size mattress may be more comfortable for couples because it gives them extra room to spread out. But while sleepers may have the space they need to rest in their preferred position without disturbing their partners, that doesn’t mean the mattress itself will feel ideal to them.
When a mattress is too soft or too firm, a topper is a convenient solution. Most toppers are between 1 and 4 inches thick, with thicker options affecting the feel of the sleep surface to a greater extent than thinner models. This type of sleep accessory acts as an extra layer that sits on top of the mattress to change its feel, without the expense and hassle of buying a new mattress. Toppers can also help extend the life expectancy of a mattress by absorbing much of the surface-level wear and tear.
We’ll highlight our favorite picks for king size mattress toppers and explain what makes them stand out. We’ll also detail other factors to consider before selecting a topper for your bed.

Saatva offers three mattress toppers to choose from, each one composed of a different material that caters to certain types of sleepers based on factors like body type and sleep position.
The “Foam” topper carries the lowest price-point and has the firmest feel of the three, which rates as medium or 5 on the 1-10 firmness scale. This one consists of a single high-density polyfoam layer measuring 1.5 inches thick. The foam conforms closely and evenly to improve alignment and reduce pressure, but its relatively thin profile won’t affect the feel of your mattress too much.
With a 3-inch profile, the “Graphite” topper is the thickest option. This model contains a top layer of memory foam infused with cooling graphite, followed by a second layer of high-density foam that serves as a supportive base. The feel is medium soft (4) and the foam layers conform very closely, so side sleepers weighing 230 pounds or less should find the topper particularly comfortable.
The “Latex” topper has a medium soft (4) feel and a 1.5-inch profile, so it can be seen as a compromise of the two foam models. The Talalay latex that forms this topper’s single layer is ventilated with small holes to push air to the surface and keep you cool, so hot sleepers should also be satisfied.
All three toppers include covers made of breathable organic cotton that wicks away moisture and elastic corner bands for keeping the topper in place. Saatva provides free ground shipping anywhere in the contiguous U.S., and you’ll receive a 45-night sleep trial and one-year warranty with your purchase.

The PandaZzz Double Quilted Topper checks a lot of boxes for sleepers who enjoy the feel of memory foam. The top layer is thin and soft for a contouring, cloud-like feel reinforced by a thicker base layer that brings the profile up to 3 inches thick. The second layer is also perforated with holes to reduce heat retention and help the topper stay cool, so people who normally find memory foam surfaces too warm should find this one more comfortable by comparison.
The cover is composed of premium, quilted jacquard fabric that gives the surface a luxuriously plush feel. The fabric is also fairly breathable for added temperature control. The bottom cover features small grooves that provide traction, so the topper shouldn’t shift or slip around even when you toss and turn.
Both foam layers absorb movement quite well, reducing motion transfer in the process. This means any light sleeper with a mattress that feels excessively bouncy can cut down on nighttime disruptions stemming from their partner’s movements. Like other memory foam toppers, this model also excels at pressure relief.
An approachable price-point and free shipping throughout the contiguous U.S. make the Double Quilted Topper a high-value pick for shoppers on a budget. The sleep trial – which spans 100 nights – is fairly long for a topper, and PandaZzz also backs this product with a one-year warranty against structural defects.
Use this SleepFoundation.org link for the most current discount on PlushBeds mattress toppers
The PlushBeds Latex Mattress Topper has a responsive feel and multiple firmnesses to support healthy spinal alignment for a wide range of people. Most sleepers may find an option that suits their needs regardless of body size, sleeping position, or preferences.
The airy Talalay latex in the PlushBeds topper provides pressure relief without excessive sinkage. The limited sinkage also traps less heat, and latex is naturally breathable. Hot sleepers may find they keep cooler on a latex topper. Latex is often a top choice for couples as well, since the material provides decent responsiveness for sex.
The wide range of thickness and firmness options ensures pressure relief and adequate support for most types of sleepers. Sleepers under 130 pounds may feel most comfortable on athicker 3-inch topper with a soft (3) or medium soft (4) feel, both of which provide more pressure relief while supporting hips and shoulders to align the spine. The medium (5) and medium firm (6) options are better suited to sleepers who weigh 130 to 230 pounds. Those weighing more than 230 pounds may prefer the extra firm (8) feel to prevent excess sinkage – especially if they sleep on their backs or stomachs.
PlushBeds offers free shipping to the contiguous U.S.. The company also provides a 5-year warranty with purchases, but returns are not permitted.
Best for Back Pain
Use this SleepFoundation.org link for the most current discount on Turmerry mattress toppers
The Turmerry Organic Latex Mattress Topper is available in profiles of 2 or 3 inches. You can also choose from a soft (3), medium (5), or medium firm (6) feel. This versatile selection makes the topper suitable for most people regardless of their body type or sleep position. If you primarily sleep on your back, the medium or medium firm feel will probably feel most comfortable. The same is true for stomach sleepers.
The topper is constructed from Dunlop latex, a dense material that cushions and conforms to the body to improve alignment and alleviate pressure in sensitive areas along the spine. Dunlop latex is a good match for sleepers who enjoy even contouring but find memory foam’s “hugging” effect too invasive. The latex is ventilated with small holes to ensure steady airflow and minimal heat buildup.
The latex has earned certifications from the Global Organic Latex Standard and the U.S. Department of Agriculture, two leading authorities for certifying organic materials. Turmerry’s manufacturing facility is also Carbon Neutral certified, and the company is committed to planting a tree for every product sold. An OEKO-TEX Standard 100 certification indicates the topper does not contain any known harsh chemicals or harmful substances.
Prices for this topper vary by thickness and firmness. Shipping is free of charge within the contiguous U.S., and you may also request an organic cotton cover for your topper at no extra cost. Each purchase is backed by a 60-night sleep trial and 5-year warranty.

Memory foam is not particularly known for sleeping cool. The foam has a tendency to absorb and trap body heat, making the material potentially problematic for hot sleepers. The GhostBed Memory Foam Topper mitigates this issue thanks to intricate channels cut that allow air to flow freely across the surface. For added breathability, the foam is infused with gel and the removable cover is made of cool-to-the-touch Ghost Ice Fabric.
Measuring 3 inches thick, the topper will noticeably adjust the feel of your mattress and is particularly well suited to people whose beds have grown saggy or uneven over time. The foam is divided into five different firmness zones, creating more support around the midsection where people tend to carry more weight and a softer feel for lighter areas of the body.
The topper’s cover is another notable feature because it encases the mattress and fits snugly around the corners of your mattress, removing the need for a fitted sheet. The pocket depth is 18 inches, so the cover will work with most mattresses sold today. Unlike other topper covers, this one is also waterproof. This makes the topper a good option for children who wet the bed.
GhostBed provides free ground shipping anywhere in the contiguous U.S. The company does not permit returns for the topper, so your order won’t come with any sort of trial period, but the purchase is backed by a 5-year manufacturer’s warranty.
Use this SleepFoundation.org link for the most current discount on Brooklyn Bedding mattress toppers
Brooklyn Bedding offers an array of toppers that cater to different firmness and performance needs. The Cooling Talalay Latex Topper is an excellent option for shoppers who are looking for a topper that will help their mattress feel cool at night.
The topper measures 3 inches thick and is made with 100% Talalay latex. It is encased in a zippered cover made of breathable knit material that is designed to feel cool to the touch. Since latex has natural cooling properties, especially compared to foam, hot sleepers should find this topper quite comfortable to sleep on. Talalay latex is also generally a less dense type of latex, which can help with temperature neutrality.
With a medium (5) firmness level, this topper moderately contours with the body and also has a slightly bouncy feel. An even balance of support and cushion makes the topper suitable for a wide range of sleepers. Side sleepers in particular will benefit from the topper’s design, since this sleep position requires pressure relief in the shoulders and hips but still requires support to other areas of the body.
Brooklyn Bedding offers free shipping within the contiguous U.S. Customers may return the topper within 30 days for a full refund. The topper also comes with a 3-year warranty.
Best for Side Sleepers
Use this SleepFoundation.org link for the most current discount on Layla mattress toppers
A mattress that’s too firm can create uncomfortable pressure points, especially for side sleepers. The Layla Memory Foam Topper is designed to enhance your current mattress’ feel without affecting its overall support level. This soft (3) topper is crafted from memory foam that hugs your body and closely contours to help prevent pressure build-up. Though this topper is compatible with any mattress, it’s designed to work seamlessly with the flippable Layla Mattress.
Memory foam is notorious for trapping heat, which can often make it a tough pick for hot sleepers. However, this 2-inch topper is made entirely of memory foam that’s infused with copper gel beads. These beads are engineered to draw excess body heat away and keep your mattress a comfortable temperature. The viscose and polyester cover also features proprietary temperature-regulating fibers.
While side sleepers are most likely to enjoy this topper, it may also appeal to back sleepers looking for a pressure-relieving option. People who weigh over 230 pounds and stomach sleepers will likely prefer a firmer model. Your purchase of the Layla Memory Foam Topper includes a 120-night sleep trial and a 5-year warranty that protects against defects in the foam and cover.
Best Pressure Relief
Use this SleepFoundation.org link for the most current discount on ViscoSoft mattress toppers
Long-lasting toppers with approachable price-points can be hard to come by, but the ViscoSoft Select High Density Mattress Topper manages to be both durable and affordable. Composed of high-density memory foam – a material that often withstands sagging and shape loss over time – the topper offers a 3-inch profile and medium (5) feel with close body-contouring. This design should lead to major comfort adjustments if your mattress is exceptionally saggy or uneven.
The foam provides plush cushioning for the shoulders and hips, which can improve alignment issues and reduce pain for side sleepers, but the dense composition also allows the topper to support back sleepers without sinking around the midsection. Since the foam absorbs motion very well, the topper may also be a good option for couples – especially if their mattress has a responsive surface that disrupts sleep.
The topper is encased in a cover made of breathable rayon derived from bamboo, which has cooling properties and a luxuriously soft hand-feel. The cover’s anti-slip bottom creates traction on your mattress surface, and each corner has an elastic strap for securing the topper to your mattress. Thanks to these features, combination sleepers who constantly change positions and people who toss and turn won’t need to worry about the topper shifting or sliding too much.
In addition to standard models, customers can choose from two special versions of this topper. One design is infused with active charcoal intended to boost the topper’s breathability and also add an extra measure of antimicrobial protection. The other is treated with lavender, which many people use as a relaxant to promote sleepiness leading up to bedtime.
Ground shipping is free of charge for all orders in the contiguous U.S. ViscoSoft backs the Select High Density Mattress Topper with a 60-night trial and return period, as well as a 5-year warranty against material defects.
There are plenty of criteria to take into account when purchasing a king mattress topper. Companies are in the business of selling, so some may try to appeal to the broadest customer base possible. Often, they make it seem like their toppers are comfortable for everyone regardless of their sleep position, weight group, existing mattress, and personal preferences. In reality, needs and preferences vary, so focusing on specific aspects may help you to find a topper that’s closer to your ideal match.
King mattress toppers vary widely in price due to differences in materials, quality, and construction. Convoluted polyfoam toppers and fiber toppers are usually the most affordable, frequently costing less than $50. Memory foam, high-density polyfoam, feather, and latex options usually cost a bit more, ranging from around $100 to $700. Down toppers generally cost the most on average, starting at around $200 and reaching over $3,000.
A sleeper’s spinal alignment and the location and intensity of their pressure points depend largely on their sleep position. The right topper can make the sleep surface more supportive and pressure-relieving for your chosen position.
For instance, side sleepers may prefer a softer and thicker topper, since it will leave more room for their hips and shoulders to sink in without pressing against their mattress. Back sleepers and stomach sleepers often prefer firmer, thinner toppers for gentle contouring without significant midsection sinkage that could jeopardize their spinal alignment.
The quality of the materials is one of the most important factors in determining a topper’s durability. High-quality materials typically resist indentations, sagging, and cracking so that you can continue to use your topper comfortably for years to come. While a topper made of quality materials will likely carry a higher sticker price, it may cost less over its lifespan than lower-quality options that require frequent replacement.
Sleeping hot is a common issue. Many toppers address this concern with special cooling features that allow heat to escape, wick away moisture, and/or make the surface feel cool to the touch. Pairing a cooling topper with a mattress that tends to retain heat may make the bed more comfortable for hot sleepers.
Firmness preferences are subject to several factors, but some people tend to prefer certain firmnesses based on their body types. Most sleepers will likely find a medium to medium firm topper comfortable, especially if they weigh between 130 and 230 pounds. However, individuals who weigh under 130 pounds usually prefer a soft or medium soft option for more hug, while those who weigh more than 230 pounds frequently favor a medium firm to firm topper for more support.
Which topper firmness is ideal for you may also depend on the feel of your existing mattress. If your mattress is too firm, you may prefer a softer topper than what is most popular for your weight group. However, if it is too soft, a firm topper may be a better option.
The thickness of the topper directly affects how much it changes the feel of the sleep surface. Most toppers range between 1 inch and 4 inches thick, with the thinner options providing a slight adjustment and the thicker models giving your bed a more significant transformation. How much you like the feel of your existing mattress and what sleep position you prefer may influence which thickness is best for you.
Many sleepers seek out toppers primarily for added pressure relief, especially if their existing mattress is too firm. Materials like memory foam, polyfoam, and latex redistribute a sleeper’s body weight to reduce pressure buildup around wider areas, like the hips and shoulders.
The thickness and firmness of a topper can contribute to the level of pressure relief an individual experiences. Thicker toppers traditionally have more pressure relief than thinner models since they have extra depth to cradle a sleeper’s curves. A firmness that corresponds to your body weight (softer for individuals under 130 pounds and firmer for those over 230 pounds) should give most sleepers the best combination of pressure relief and support.
There isn’t one right answer as to which variety of mattress topper you should choose. Each type carries potential benefits and drawbacks that may make them ideal for some individuals and uncomfortable for others.
To select the best variety of mattress topper for you, you should assess your priorities, preferences, sleep position, and existing mattress. Knowing more about the different types of toppers may also make the decision easier.
Polyfoam toppers, especially those with convoluted foam, tend to be some of the most affordable options on the market. These toppers typically regain their shape more quickly and allow more airflow than memory foam, while also contouring to the sleeper’s body for pressure relief and support. However, lower-density, lower-quality polyfoam toppers may wear out faster than other types of toppers.
Memory foam conforms closely to the sleeper’s body, thereby distributing their body weight and relieving pressure. Since memory foam toppers tend to regain their shape relatively slowly when pressure is removed, they absorb a significant amount of motion but have little to no bounce. Toppers made of traditional memory foam are prone to heat retention, but some models use gel infusions or phase change material in the cover intended to help transfer away excess warmth.
Latex toppers may use natural, synthetic, and/or blended latex, though natural latex tends to be most popular because of its sustainability. To create natural latex, sap from rubber trees is formulated using either the Talalay or Dunlop process, both of which create a durable, breathable, and buoyant material. Latex toppers redistribute weight to relieve pressure, but the material’s low point elasticity provides more of a floating sensation than a full-body hug.
Feather and Down
Feather and down toppers, sometimes called featherbeds, typically use duck and/or goose feathers, down, or a combination of the two. Down is the plush inner plumage of a bird, which gives toppers a fluffy, light feel, but also carries a higher price tag. Feather toppers are usually more supportive and less expensive. While both feather and down toppers can feel luxurious, they do not typically provide the same level of pressure relief as foam. They may also allow more motion transfer, make a rustling noise, emit an odor, and/or trigger allergy symptoms.
Wool toppers cushion the sleep surface without the same contouring as foam. Perhaps the biggest benefit of wool toppers is their temperature regulation. Wool insulates when it’s cold, draws heat away when it’s warm, and wicks away moisture, allowing for all-season usage.
Using two twin XL toppers instead of one king topper may be a good option for some couples, but it also has potential drawbacks. It’s beneficial in that each partner can select their ideal firmness rather than trying to find a compromise. Additionally, since the toppers are two separate pieces, motion transfer should be minimal.
But using two twin XL toppers is not without drawbacks. If you or your partner gravitate toward the center of the bed, you may feel the line where the two pieces meet, which may be uncomfortable. Some toppers are anchored in place with corner straps. When used in place of a king topper, two of the straps on each twin XL topper would not have a corner to hold it in place, so they may move around more. If either component shifts during the night, it could create a gap in the center of the bed.
King toppers usually cost between $100 and $400, but options are available for most budgets. Affordable options start at just $20, while luxury models can cost over $3,000. Price is often determined by the brand, construction, and materials.
There are important differences between king and California king sizes, which shoppers should consider before making a purchase. A king size is wider, while a California king size is longer. More specifically, a king typically measures 76 inches by 80 inches, compared to a California king’s 72 inches by 84 inches. If you want to have more room to roll over or change positions without disturbing your partner, you may prefer a king size. However, if you or your partner is especially tall, a California king may be more comfortable.
To avoid damage, mattress toppers should only be cleaned following the manufacturer’s care instructions. Each topper may have different instructions based on its materials. Those that contain memory foam, polyfoam, or latex cannot be washed but can usually be spot cleaned if necessary. Some also have removable, washable covers. Select fiber, wool, feather, and down toppers may be machine-washable depending on their constructions. Using a waterproof mattress protector over your bed can also help prevent dirt and stains.
