While the allure of spaciousness is undeniable, it’s important to take other factors into account when choosing the right king mattress. These include not only mattress quality and performance, but also your budget, bedroom size, and even the logistics of moving the mattress. 

Fortunately, we’ve done the heavy lifting by trying a wide range of king mattresses. In this guide, we’ll walk you through our team’s choices for the top king mattresses on the market. If you’d like to learn more about the top mattresses overall, check out our guide to best mattresses of 2024.

The Helix Midnight takes the top spot for a king mattress because of its versatility. It’s effective for a wide variety of sleep positions, limits vibrations across the mattress surface, and offers an appealing balance of cushioning and support.

Mattress Type

Hybrid

Firmness Options

Medium Firm (6)

Trial Period

100 nights (30-night requirement)

Full Details

Who it’s best for:
Our testing team found the Helix Midnight was a great match for side and back sleepers who weigh less than 230 pounds. Bed partners appreciated how it reduced sleep disruptions by containing almost all the vibrations from a partner’s movement.

Feel:
The Helix Midnight is medium firm (6) and has the ability to gently cradle joints like the hips and shoulders without sacrificing its flat, even surface. It resists overheating and prevents you from noticing most movement on the other side of the bed.

What it’s made of:
The Helix Midnight has two comfort layers, one made with memory foam and another with a responsive polyfoam. The central support core includes a thick layer of metal coils and an underlying layer of polyfoam.

What we don’t like:
Although suitable for many sleepers, it lacks firmness for some people over 230 pounds. It’s not quite springy enough for people who want a very bouncy sleep surface.

We performed a meta-analysis on 6653 validated customer reviews of the Helix Midnight. This is what people who bought the mattress had to say:

  • Comfort and Firmness: Many reviews mention the comfort level of the mattress, indicating it is generally well-received for its balance between firmness and softness.
  • Heat Regulation: There are mixed comments regarding heat regulation, with some finding the mattress cool enough, while others still experience heat retention. We found the mattress to regulate temperature better than the average hybrid, but beds with foam comfort layers always run the risk of retaining body heat.
  • Pain Relief: A common theme is the relief from back, hip, or shoulder pain, suggesting the mattress is effective for those with chronic pain or side sleepers.
  • Durability Concerns: Some reviews express concerns about the mattress’s durability, noting issues like sagging or indentations over time.
  • Sleep Quality: Numerous reviewers state that their sleep quality has improved, mentioning deeper sleep and less discomfort during the night.
  • Edge Support: The edge support of the Helix received mixed reviews, but the overriding sentiment is that it’s firm enough to support your weight when sleeping near the edge. This backs up what we’ve found in our field and performance testing.

Who it’s best for:
The DreamCloud is a near-perfect match for side and back sleepers between 130 and 230 pounds, but it can provide solid results for almost any sleeper. Because it isolates motion on the other side of the bed, it’s also a strong choice for couples.

Feel:
This is a medium firm (6) mattress that feels luxurious thanks to its cashmere cover and foam top layers. At the same time, its robust hybrid design makes it sturdy and supportive enough to keep you from sinking too deeply into the bed.

What it’s made of:
Underneath its cashmere cover, the DreamCloud features a polyfoam top layer followed by layers of memory foam and polyfoam. The supportive core of this mattress is made of pocketed coils, which give it that traditional bouncy feel without excessive noise or vibrations across the mattress.

What we don’t like:
There have been reports from customers of indentations and sagging after a few years. It’s also not the easiest bed to move around on, so if you toss and turn, the DreamCloud might not be your perfect match.

Who It’s Best For

All sleeping positions have touted benefits from this mattress, but side sleepers in particular mention improvements in sleep quality and pain relief, and back and stomach sleepers praise its balance of firmness and cushioning.

The Essential mattress features a quilted cotton-polyester cover, a high-density polyfoam layer, responsive pocketed coils for support, and a polyfoam base for stability and durability.

What We Don’t Like

Who it’s best for:
The WinkBed’s distinct firmness models suit many types of sleepers. The Luxury Plush WinkBed (6) is the most popular, especially with side and back sleepers under 230 pounds. Durable perimeter support makes it a winner with people who sleep or sit near the edge of their bed.

Feel:

What it’s made of:
All of the WinkBed models have a support core of metal coils. Most models have polyfoam top layers, but the WinkBed Plus, which is designed with sleepers over 230 pounds in mind, swaps out a polyfoam layer for natural latex that provides additional pushback.

What we don’t like:
The bounce of the WinkBed can cause motion to spread from one side of the bed to the other, which can disrupt people who sleep lightly.

The Birch Mattress is medium firm (6) and offers light cushioning, significant bounce, and robust edge support. Our testing team loved how it stayed cool and made it easy to move around on the mattress surface.

What it’s made of:
The cover of the Birch is composed of organic wool and organic cotton. Inside, the top layer is made of organic latex that adds bounce and durability. The support core features thick pocketed coils that make the mattress feel sturdy, including around the perimeter.

What we don’t like:
The Birch Mattress uses responsive materials that can cause vibrations from a bed partner’s movement to be felt on the other side of the mattress. It may feel a touch too firm for some side sleepers under 130 pounds.

Watch the video below to learn more about our top picks for best king mattress.

If you’re curious to learn more about our picks, read our reviews below. At the bottom, we also provide a buyer’s guide to shopping for king size mattresses. Our guide offers practical advice on how to find the right king mattress, which types of sleepers will benefit from these mattresses, and which mattresses are best for a king size.

How We Test: Rigor, Data, and Sleeper Feedback

Our team uses an objective rating system that takes all important sleeper needs into consideration. By taking a holistic look at mattresses, we can determine the pros and cons of each model in order to help you make the best purchasing decision.

We understand the connection between sleeping on a mattress suited to your sleep style and getting high-quality sleep each night. Our team personally evaluates each mattress in our Seattle-based Test Lab using a four-step process, which you can read about in detail below.

Construction analysis: Mattress construction plays a major role in how the bed feels and performs. To kick off our hands-on tests, we’ll perform a detailed analysis of the mattress’ design and take note of manufacturer specs such as firmness, thickness, and layer density.

Product testing: Our team runs each mattress through the same series of hands-on tests, during which we’ll use various tools and technology to evaluate each model for six performance categories. These tests help us calculate ratings for important qualities like pressure relief, temperature control, and edge support.

Field testing: We rely on feedback from field testers, members of our team who use mattresses in their own home over the course of several weeks. Field testing data helps us understand how mattresses perform night after night.

User testing: Real mattress owners also influence our product ratings. We collect data from surveys and mattress reviews, then weigh this data against our own findings to ensure accuracy and inclusivity.

Who Should (and Shouldn’t) Sleep on a King Size Mattress?

A king-sized mattress can anchor your bedroom and maximize your sleeping space, but this size isn’t for everyone. We find that king mattresses are ideal for:

  • Couples: Ample space so both partners can enjoy undisturbed sleep.
  • Families: Perfect for co-sleeping and lazy weekends.
  • Pet owners: Giving pets space without crowding their humans.
  • Tall sleepers: Extra width for those who like to spread out.

On the flip side, a king mattress may not suit:

  • Singles: May be excessive for those sleeping solo.
  • Small spaces: Can overwhelm tighter rooms.
  • Budget shoppers: Typically pricier than smaller mattresses.
  • Frequent movers: Can be challenging to transport.

Are There Different Kinds of King Size Mattresses?

King mattresses come in various styles, each with slightly different dimensions. A standard king is 76 inches wide and 80 inches long, making it 16 inches wider than a queen. A California king adds 4 inches in length, while a split king pairs two twin XLs to allow for separate firmness levels in one bed. Alaskan and Texas kings are some of the most spacious oversized mattresses on the market.

Split King76″ x 80″
California King72″ x 84″
Alaskan King108″ x 108″
Texas King80″ x 98″

What to Consider When Shopping For a King Mattress

While many people choose a king mattress for its size, it’s important to remember that mattress shopping is about finding the right combination of comfort, support, and value. To make the process a bit easier, we’ve put together the following list of factors to consider when shopping for a king mattress.

Your Sleeping Position and Weight

Side sleepers tend to prefer a softer bed that conforms under their hips and shoulders, while back and stomach sleepers benefit from firmer mattresses that offer increased support. If you weigh under 130 pounds, you might gravitate towards a plusher surface, while if you’re over 230 pounds, a firmer option might be more suitable.

Mattress Type and Height

Several mattress types dominate the market, each with unique advantages:

  • Innerspring: Bouncy with good airflow, these are often the most budget-friendly king mattresses.
  • Foam: Conforming and pressure-relieving, the performance of an all-foam king mattress depends on the types of foams used in its construction.
  • Latex: Latex kings are responsive and durable beds popular with eco-conscious shoppers, but can be expensive.
  • Hybrid: Many of our favorite king mattresses are hybrids that combine the benefits of an innerspring core with layers of foam or latex.

The height of a mattress also affects its aesthetics and performance. When shopping for a king mattress, consider if a taller or shorter design suits your preferences in terms of style, price, weight, and the ease of getting in and out of bed.

Transportation and Bedroom Space

Before buying a king mattress, keep in mind that this bed size is inherently large and heavy. Make sure that your bedroom has enough space to accommodate a king mattress and consider how you’ll get it into your bedroom. Pay special attention to any narrow hallways and doorways and be sure to enlist a friend or two for help.

Edge Support and Motion Isolation

Two of the most important performance factors for a king mattress are edge support and motion isolation. Edge support refers to the mattress’s strength and stability on its sides, important for maximizing sleeping space and preventing sagging at the edges. Motion isolation reduces the likelihood that you’ll be disturbed by a co-sleeper’s movements.

Budget and Pricing

King mattresses typically carry a heftier price tag than smaller sizes. Factors influencing the cost of a king include material, quality, brand, and added features. If you’re shopping on a budget, keep your eyes out for discounts, promotional bundles, and seasonal sales.

Trials, Returns, and Warranties

A king mattress can be a significant investment, so understanding trials, returns, and warranties is crucial. Trials allow a risk-free way to try a mattress before commiting. Returns allow you to send it back if you’re unsatisfied, and warranties protect against manufacturing defects. Ensure these policies are transparent and suit your needs when hunting for your perfect king mattress.

Frequently Asked Questions

How big is a king size bed?

A king mattress is typically 76 inches wide and 80 inches long. Height and weight vary, but these beds are usually around 9 to 12 inches tall and weigh over 100 pounds.

Who is a king mattress best for?

The added space of a king mattress makes it ideal for couples seeking more space, families who co-sleep or hang out in bed, pet owners wanting room for their furry friends, and taller individuals who appreciate the added width.

How much does a king mattress cost?

The price of a king mattress can vary significantly based on its materials, brand, and added features. On average, you can expect to spend anywhere from $900 to over $2000 on a king mattress. Because these beds can be a big investment, it’s wise to research and set a budget before making a purchase.

What is the biggest bed size available?

The Family XL, at 144″ wide and 84″ long, is the biggest oversized mattress on the market. While the Alaskan King is often noted for its generous 108″ x 108″ dimensions, the Family XL surpasses it in width by an impressive 3 feet. Oversized options like the Family XL can be challenging to find, and require custom frames and bedding.

What is a “king’s ridge” and how can you avoid it?

A king’s ridge refers to a hump that can form in the center of a king mattress that can develop in outdated or low-quality mattresses as they begin to sag in several areas. To keep the king’s ridge at bay, invest in a high-quality mattress, regularly rotate your bed, and don’t forget to replace it every 7 to 10 years.
