The Brooklyn Bedding Signature is a standout king size mattress thanks in part to its top-tier design. We’ve put the Signature through rigorous testing, and it emerged as one of the top-rated mattresses on Tuck Sleep, with high-quality hybrid construction at an affordable price-point.

Beneath a quilted polyfoam cover, the Signature’s comfort system is constructed from two 2-inch layers of cooling gel-infused polyfoam, and the support core features 6 inches of pocketed coils and 1 inch of high-density polyfoam.

Though this construction remains consistent, the Signature’s feel varies significantly depending on its firmness level. For customers who choose the right option for their weight and sleep preferences, this customization allows for an ideal blend of pressure relief and support. The soft option, for example, offers a plush, deeply contouring mattress for lightweight sleepers, while the medium and firm firmness levels balance this against — or partially exchange it for —significantly firmer support with minimal sinkage.

Premium materials and top-of-the-line construction allowed the Signature to shine in our testing process, and it earned four stars in all but one of our sleep categories. Couples will particularly appreciate the mattress’s above-average motion isolation, edge support, and suitability for sex, but the Signature is an appealing choice for almost all customers in search of the best king size bed.

The Bottom Line.

With three firmness options and top-of-the-line hybrid construction, the Brooklyn Bedding Signature mattress offers customized support for a wide variety of sleepers. The Signature is one of the top-rated mattresses on Tuck Sleep, with an affordable price-point which also makes it one of the best deals available on a king size bed.

  • Almost all sleepers, regardless of weight or sleep position preference. Given the choice of firmness options and the Signature’s impressive performance in our testing, it’s no surprise that nearly all sleepers can find a version of the mattress which suits them well.
  • Couples. King size beds offer plenty of room for couples, and the Signature’s high ratings for motion isolation, edge support, noise, and suitability for sex make it an attractive option.
  • Shoppers on a budget. Although priced higher than many all-foam models, the Signature has below-average pricing for a hybrid mattress.
  • Hot sleepers. Gel comfort layers and airflow through the pocketed coils still allow for very good temperature regulation.

Not Recommended for...

  • Stomach sleepers over 130 pounds. During our testing, our sleepers in this category enjoyed the Signature but found it offered them less support than it offered testers of other weights or position preferences

Best LatexLatex for Less

Shop Now

Founded in 2014, Latex for Less is an online mattress retailer specializing in natural latex bed products. The Latex for Less is currently the company’s only mattress model and is our pick for Best Latex Mattress, as it combines quality with value.

The Latex for Less is a low-profile, flippable design with dual firmness levels, medium firm and fim. There is also the choice of two thicknesses, 7 or 9 inches, but even the latter is still considered low-profile.

The Latex for Less combines natural latex and wool to create a heat-wicking, airy mattress. Both the 7 and 9-inch models contain two separate layers of .5-inch natural wool for extra padding, as well as a GOTS certified organic cotton cover.

The 9-inch version differs from the 7-inch in that it features two levels of latex instead of one. The side with the medium firmness level on the 9-inch model features a ventilated Talalay latex comfort layer for a more responsive feel. The reverse firm side is made with Dunlop latex for greater support. Since this is a flippable design, each latex comfort layer functions as the support core when the reverse side is in use.

The 7-inch Latex for Less Mattress includes a 6-inch layer of ventilated Dunlop latex. One side has a medium firmness level, while the reverse is firm for additional support. Because of its lower profile, the 7-inch model feels slightly firmer on each side when compared to the 9-inch mattress. Sleepers under 130 pounds or children often prefer shorter mattresses, in which case the 7-inch version might be a better fit.

The natural Talalay latex used in the 9-inch model is OEKO-TEX Standard 100 certified to be free of harmful chemicals, and the Dunlop latex in both mattresses is OEKO-Institut certified to be similarly non-toxic. Both Latex for Less models come in six sizes: twin, twin xl, full, queen, king, and California king.

Latex for Less offers free ground shipping, and the mattress arrives boxed and wrapped in vacuum-sealed plastic. The mattress is also backed by a 120-night sleep trial and a 20-year limited warranty.

The Bottom Line.

A flippable, low-profile model with dual firmness levels, the Latex for Less Mattress is made with natural latex, wool batting, and an organic cotton cover. The mattress is available in two different thicknesses, 7 or 9-inch, as well as six sizes. Combining quality materials with versatility, the Latex for Less is our pick for Best Latex Mattress.

  • Hot sleepers. The Latex for Less Mattress is excellent at regulating temperature, thanks to its ventilated latex and breathable cotton cover. The wool batting layers also dissipate excess heat.
  • Couples. The Latex for Less Mattress is very quiet since it absorbs movement and reduces motion transfer. A quieter mattress is an asset for couples, as you’re less likely to be disturbed by your partner’s movement.
  • Value-seekers. Latex models tend to last longer than other mattress types, and when combined with other quality materials and a 20-year warranty, the Latex for Less is an excellent value mattress.
  • Sleepers who prefer low-profile models. Whether you opt for the 7-inch or 9-inch model, the Latex for Less has a below average profile. The 7-inch is exceptionally low-profile and will often appeal to sleepers under 130 pounds or children.

Not Recommended for...

  • Side sleepers less than 130 pounds. The Latex for Less Mattress might be too firm for this type of sleeper, as they usually prefer a plusher feel that cushions the hips and shoulders, thereby alleviating pressure points.
  • Those needing a high-profile mattress. This model’s lower profile might make it difficult for some people to get in and out of bed.

Best Memory FoamLive & Sleep Elite

Shop Now

The Live & Sleep Elite is a firm (7) memory foam mattress that provides cooling comfort and total body support. Live & Sleep also makes two other mattresses, the Classic and Luxury, as well as one pillow model.

The Live & Sleep Elite is 10 inches thick and features a responsive, 2.5-inch premium memory foam comfort layer. There is a .5-inch gel-infused memory foam layer that conforms to the body, alleviates pressure points, and helps keep sleepers cool. Beneath these two layers is a 7-inch high-density total body support core, and the mattress’ outer layer consists of soft, woven-knit fabric.

The Live & Sleep Elite is especially suited for side and back sleepers, thanks to the body-conforming nature of memory foam. By cradling a sleeper’s shoulders and hips, pressure points are alleviated and potential back pain is minimized. The Live & Sleep
Elite’s high-density foam encourages proper spinal alignment and provides total body support.

The Elite Mattress is also great for hot sleepers, as the gel-infused memory foam layer dissipates heat. The foam is hypoallergenic and CertiPUR-US certified to be free of harmful chemicals, making the mattress suitable for those with various sensitivities.

Live & Sleep provides free and efficient shipping within the Continental U.S. for their Elite mattress, as well as a 75-night sleep trial. A portion of each purchase is donated to charity.

The Bottom Line.

The Live & Sleep Elite is a firm memory foam mattress and is excellent at providing total body support while also keeping sleepers cool.

  • Sleepers who prefer a firm feel. The Live & Sleep Elite Mattress has a firm feel and is ideal for those seeking additional support, particularly stomach sleepers.
  • Those who prefer a mattress with a higher profile. Its 10-inch-thick design is great for sleepers who prefer a higher profile. Sleepers over 130 pounds often do well with a thicker, sturdier mattress.
  • Value-seekers. By removing the middleman, Live & Sleep keeps their mattress pricing more accessible. When compared to other memory foam mattresses of similar quality, the Elite is competitively priced.
  • Those in need of different sizing options. In addition to offering the standard mattress sizes (twin, twin xl, queen, king), the Elite is also available in California king and short/RV queen sizes.

Not Recommended for...

  • Sleepers who prefer a softer mattress. The Live & Sleep Elite might not appeal to those who prefer a plusher feel, in which case the Classic or Luxury models may be more suitable.
  • Side sleepers under 130 pounds. Similar to the above, side sleepers less than 130 pounds might find the Elite too firm to provide cushioning to the shoulders and hips, which is needed to alleviate pressure points. This type of sleeper would do better with the Live & Sleep Luxury Mattress, which has a medium firmness level.

Best HybridDreamCloud Mattress

Shop Now

Innersprings still appeal to some sleepers because of their strong support systems, springy surfaces, and consistent temperature control. The DreamCloud is technically a hybrid as opposed to a traditional innerspring, but this model offers many of the features and characteristics that have made coil mattresses popular over the years.

For one, the DreamCloud is quite tall. Its 14-inch profile is quite thick compared to the average mattress. The feel is considered medium firm (6.5), but the surface also feels plush and comfortable thanks to a quilted cover padded with memory foam. The cover’s outer fabric consists of a cashmere blend that helps the mattress sleep very cool.

The DreamCloud’s support core contains thick pocketed coils that stabilize the mattress quite well and protect the edges from deep sinkage when owners get in and out of bed. The coils also promote some interior airflow for added cooling and temperature regulation.

Considering its tall profile and luxurious design, the DreamCloud is exceptionally low priced for a hybrid model. Shipping is also free within the contiguous U.S. Each customer receives a sleep trial with their purchase that allows them to test out the mattress for up to 365 nights – much longer than average. A lifetime warranty is also included.

The Bottom Line.

The DreamCloud offers a luxe high-profile design and premium materials at a very approachable price-point. This hybrid mattress excels at edge support and temperature control.

  • People who weigh at least 130 pounds. Due to the DreamCloud’s medium firm feel, the mattress is best suited to people in the average weight and heavyweight groups.
  • Hot sleepers. As is the case with most hybrids, the DreamCloud regulates temperature well thanks to steady air circulation through the coil system. The mattress gets an extra boost from its breathable cashmere-blend cover.
  • People who enjoy sleeping on tall mattresses. The DreamCloud is 14 inches thick, making it a high-profile model that should be comfortable for anyone who prefers tall beds.
  • Those who want to buy a mattress with a lengthy sleep trial. The DreamCloud comes with a sleep trial of 365 nights, one of the longest in the industry.

Not Recommended for...

  • Lighter side sleepers. Those who weigh less than 130 pounds and primarily sleep on their sides will probably find the DreamCloud too firm, and added pressure points may develop as a result.
  • People who awaken easily due to movement in bed. The DreamCloud’s responsive feel may cause motion to transfer across the surface – a common source of sleep disruptions for couples – when someone moves in bed.

Best CoolingSaatva Classic

Shop Now

With luxury touches at an affordable price, the Saatva Classic offers four king size variants to choose from, in addition to three firmness levels and two thickness options. Traditional innersprings like the Saatva allow for the most airflow, keeping even the warmest sleeper cooler than the other mattresses on our list.

The Saatva is also reasonably sustainable for an innerspring. The cover is made of ultra-soft organic cotton and includes a flame retardant barrier made using thistle pulp. All thickness and firmness options include a dacron-fiber pillow-top for a supportive plush surface, as well as a 1-inch polyfoam comfort layer which improves pressure relief.

Beneath the comfort layers is the first of the Saatva’s two coil layers: four inches of medium-gauge pocketed coils for a balanced feel. Following this is four or seven inches of recycled steel Bonnell coils (depending on the mattress thickness chosen), for a coil-on-coil design which offers better support and pressure relief than traditional innersprings.

Due to having three separate areas to customize, as well as offering targeted support with its coil-on-coil construction, the Saatva is likely to appeal to a wide range of sleepers.

The Bottom Line.

Innerspring mattresses sleep cooler than most other mattress types, but the Saatva’s charms extend beyond its superior temperature neutrality. Features like eco-conscious construction, customizable options, and luxury touches are matched by an affordable price, making the Saatva a great deal with broad appeal.

  • People who sleep warm. Thanks to their superior airflow, innersprings are one of the coolest types of beds, and the Saatva offers a pressure-relieving coil-on-coil design to improve on the traditional model.
  • Customers in search of king size variants. With four king size variants to choose from, including the hard-to-find California split king, the Saatva has the highest number of king sizes to choose from on our list.
  • Eco-conscious customers. Although the Saatva uses some synthetic materials, its use of organic cotton, recycled steel coils, and botanical anti-bacterial and flame-retardants make it a more sustainable option than many competitors.
  • Sleepers on a budget. Considering its many luxury touches and excellent performance, the Saatva has an extremely reasonable price-point.

Not Recommended for...

  • Light sleepers. The Saatva performed poorly in our motion isolation tests due to the interconnected nature of its innersprings, making it less viable for anyone easily disturbed by referred movement.
  • Anyone in need of targeted pressure relief. While the Saatva’s comfort system and pocketed coil layer do provide better pressure relief than a traditional innerspring, those who require significant pressure relief should look elsewhere.

King Size Mattress Buying Guide

In the guide below, we’ll share everything you need to consider when buying a king size mattress, including pros and cons, king size variants, and the most common mattress material types.

What Is a King Size Mattress?

Introduced in the 1940s, king size mattresses are the largest standard size beds on the market. While variants are available, standard North American king size beds are 76 inches wide by 80 inches long. This works out to 6.3 feet wide by 6.6 feet long, which is the same length as a queen bed but significantly wider.

Why Buy a King Size Mattress?

Couples, parents, and pet owners often gravitate towards this size and its variants, as the extra space means there’s plenty of room for two or more sleepers. Interior design fans and those in search of a luxurious touch also tend to appreciate the king size for its aesthetically pleasing shape and opulent look.

However, if your heart is set on one of the more obscure variants (such as Alaska king), you might struggle to find it. King size beds also have a price tag to match their size, and can be heavy enough to make moving or repositioning them difficult.

  • Plenty of room for couples, families, and pet owners
  • Aesthetically pleasing, nearly square shape
  • Standard and California king sizes are widely available


  • More expensive than other mattress sizes
  • Can be very heavy and difficult to reposition or move
  • Larger than other beds and hard to fit into small rooms

What to Consider When Buying a King Mattress


  • Foam: Made from materials like polyfoam and memory foam, all-foam beds have support cores made from high-density foam. While they have their downsides, such as low durability and a tendency to sleep warm, foam mattresses are among the most affordable on the market, are nearly silent,  and have excellent motion isolation.
  • Innerspring: Though most have thin comfort layers made from polyfoam, as well as a polyfoam base layer, the majority of an innerspring mattress is taken up by connected steel coils. This traditional mattress type is affordable and supportive, with superior airflow. However, they can also be noisy, with poor motion isolation and pressure relief.
  • Hybrid: Combining synthetic foam or latex with a pocketed coil support core, hybrid mattresses attempt to offer the benefits of these materials with fewer of the downsides. While the best hybrids achieve this with excellent scores across the board, they sometimes have high price-points and a tendency towards shorter lifespans.
  • Latex: While synthetic foams dominate the market, durable latex — extracted from rubber trees and manufactured as Dunlop or Talalay latex foam — is a cooler-sleeping, more natural alternative. Latex beds also offer good pressure relief, but they have downsides in the form of their weight, cost, and weak edge support.
  • Airbed: Made with either a thin foam layer or no comfort layer at all, airbed mattresses use inflatable chambers for support. They can be extremely customizable, allowing them to offer targeted support and pressure relief, and often have long lifespans. However, they can be expensive, are hard to find, and require maintenance.

Firmness and Feel

Preferences vary, but generally people under 130 pounds like softer beds, while those above 230 pounds find firm beds more comfortable, and those in the middle prefer softer or firmer beds depending on their sleep position. This is because sleep position preference also plays a major role in choosing the right mattress.

For example, side-sleepers usually require good pressure relief, as they have a tendency to develop pressure points at their hip and shoulder. Personal taste also plays a part, with the question of whether someone likes to feel as though they are sleeping ‘in’ or ‘on’ a mattress being left up to preference.

Bedding and Bed Frames

When purchasing a bed frame or bedding for your king size bed, it’s critical to make sure you have the right size. Variants like split and California king mattresses are a different shape than ordinary kings, and some mattresses are thicker than others.

Other Types of King Mattresses

While king is the original, there are also many king size variants. These range from the very common to the very uncommon, which may limit your choice of mattresses if you decide on a rare variant.

  • California King: The most common variant, California king beds are four inches longer and four inches narrower. This is ideal for tall sleepers, but less practical for families and pet owners in need of personal space. California kings are often the same price as a standard king.
  • Split King: Split kings are two twin XL mattresses which are placed side by side and are able to attach to one another. Couples often enjoy these beds and appreciate the lack of motion transfer.
  • Alaska King: One of the rarest king size variants, Alaska king mattresses are a massive 108 inches by 108 inches, or 9 feet square. Though hard to find, these beds are the largest on the market.
  • Wyoming King: Another rare variant is the Wyoming king, which is 84 inches, or seven feet, square. These are closer in size to the standard king, but are wider, longer, and perfectly square.

How to Find a Cheap King Size Mattress

As the largest mattresses on the market, some king size beds also come with an equally large price tag. To help our readers find the best king size mattress for them at a price they can afford, here are our three favorite tips for finding a budget bed:

  • Buy your mattress at the right time. The mattress industry tends to repeat sales at the same time every year, often around holidays. By timing your purchase, you’ll have a wide selection to choose from.
  • Shop online. Most internet-based mattress companies offer sleep trials and free shipping, on top of cutting out the cost of overhead and supplying exclusive deals. Online retailers also allow you to avoid the stress of in-person sales days.
  • Sharpen your bargain-hunting skills. When shopping in-person, it’s important to do everything you can to bring the price down. Negotiating with the staff is sometimes possible, and price-matching can be a good tactic where accepted.

King Size Mattress FAQ

  • Why buy a king size mattress?

    A king size mattress provides ample room for two or more sleepers, making it ideal for those who share a bed with a spouse, their children, a pet, or any combination thereof. Some individuals also prefer king size beds due to their aesthetically pleasing, nearly square shape.

  • What are the deminsions of a king size mattress?

    In North America, the standard king size bed is 76 inches wide by 80 inches long, making it the same length as a queen size, but significantly wider. Additionally, there are some variants on the king size with different measurements. A split king adds up to the same measurements but takes the form of two twin XL mattresses placed side-by-side. The California king size measures 72 inches wide and 84 inches long, giving tall sleepers more vertical room. An Alaska King measures 108 inches wide by 108 inches tall, and a Wyoming King measures 7 feet square.

  • Can I purchase a king size mattress in a box?

    Yes, many online brands offer bed-in-a-box mattresses in a standard king size. These brands will compress and roll-pack the mattress in plastic so that it may be shipped in a relatively small box right to your doorstep. However, specialty king sizes such as split king and California king are somewhat more difficult to find.

  • How can I protect my king size mattress?

    There are several types of mattress protectors and encasements that can help protect your king size mattress from various irritants, such as liquid spills, stains, dust mites, bed bugs, and allergens. Waterproof mattress protectors are a good idea if you plan on sharing the bed with a small child or a pet.
