Best King Size Pillow

Why It’s Best Overall

The Saatva Latex Pillow is a versatile model for sleepers who want a pillow that adapts to your body without sacrificing support. It’s also ideal for shoppers who prioritize pillows made with cooling materials.

How It Performed

The pillow excels at cushioning but is still firm enough to prevent your head from sinking too deep. You can choose between two loft options. The standard loft model is 4 to 5 inches thick while the high loft model is 6 to 7 inches thick. We recommend the taller model for side sleepers, since this group needs substantial loft to fill the space between the neck and bed surface. The thinner pillow is well suited for back sleepers, but it should also feel comfortable for side sleepers who prefer a lower loft. Some stomach sleepers enjoyed the low loft model, but most will likely find it too thick.

Regardless of the loft you choose, this pillow excels at temperature regulation. The materials are naturally breathable, so there is little risk of overheating as you might with a foam pillow. 

What It’s Made of

The Saatva Latex Pillow has a dual chamber design. The inner chamber is composed of shredded latex that gives the pillow a supportive yet responsive feel. The outer chamber contains plush microdenier fibers that conform to your head and neck for pressure relief. The shredded design of the latex core allows air to flow through the pillow, which promotes breathability. The entire pillow is encased in a soft cotton cover.

The pillow is available in a standard/queen or king size. You can remove and machine wash the pillow cover and the microdenier pillow insert, but the latex core cannot be washed.

Saatva offers a 45-night sleep trial and a one-year warranty. Shipping is free to addresses in the contiguous U.S.

The Brooklyn Bedding Premium Shredded Foam Pillow delivers top-notch pressure relief and comfort without breaking the bank. This affordably priced pillow has a unique fill and cover design that allows you to craft your perfect loft level. 

How It Performed

The side and back sleepers on our team found this pillow most comfortable. Its default 7-inch loft level and medium feel are a bit too tall and firm for stomach sleepers, who typically prefer softer, shorter pillows. Testers described it as fairly easy to mold into your desired shape. 

They also noted that this pillow is an excellent option if you’re a hot sleeper. The cover fabric and fill materials provide significant temperature control, especially for a pillow with this much foam. 

What It’s Made Of

Inside the pillow there’s shredded gel-infused memory foam and latex fill that you can add or remove to create your perfect loft and firmness levels. During sleep trials, the fill adapted well to each sleeper’s unique head shape and cushioned the head and neck, which was especially helpful for sleepers prone to developing pressure point discomfort. 

The cover fabric is made from bamboo-derived material that’s cool to the touch and breathable. Our team noted that the cooling cover kept this pillow from feeling too hot and that it regulated temperature effectively throughout the entire night. 

On laundry day, wash only the cover. You can spot clean the insert when necessary. Brooklyn Bedding offers customers a 30-day sleep trial and free shipping within the contiguous U.S. Shipping is available to Alaska and Hawaii for an additional charge.

Our product testing team gave the Cozy Earth Silk Pillow high marks in nearly every one of our testing categories. It has a higher price point than other king size pillows, but the cost may be worth it for discerning shoppers who want a truly luxurious option. 

How It Performed

This pillow has a medium soft firmness level that the side and back sleepers on our team appreciated most, though stomach sleepers under 230 pounds also rated it highly. It molds easily to fit your head shape and bounces back to its original dimensions extremely well. 

We found that this model also holds up very well during durability testing. The materials are high-quality and made with top-notch craftsmanship that helps extend the pillow’s overall lifespan. 

What It’s Made Of

As the name implies, this pillow has a silk fill. It’s a unique fiber made from 100 percent long-strand mulberry silk that feels incredibly soft and plush. Air flows easily through the fill, which helps keep the pillow from feeling too hot or stuffy. The shell material is viscose from bamboo fabric that’s also breathable enough to help combat heat retention. 

Cozy Earth has a 10-year warranty in place in case the fill shifts or breaks down, though we found it to be quite hard-wearing. However, you do need to take care when washing this pillow, as silk is fairly delicate. Spot or dry cleaning is best, though you can also put the pillow in your washing machine on the rinse only cycle. You can tumble dry on low or hang dry the pillow. 

In addition to the warranty, Cozy Earth also offers customers a 100-night sleep trial that allows you to see if you like the pillow. Free shipping is also available to shoppers in the U.S.

If you’re primarily a side sleeper, chances are you need a thicker, firmer pillow that fills the space between your head and downward-facing shoulder — this helps ensure even alignment and minimal pressure along the spine. Helix’s GlacioTex Cooling Memory Foam Pillow is available in a 5.25-inch loft that’s very well suited for side sleeping. If you’re a back or stomach sleeper, or a combination sleeper who uses both of these positions, you’ll probably prefer the lower-loft 4.75-inch pillow instead.

How It Performed

The thicker GlacioTex Cooling Memory Foam Pillow was a hit among all of the side sleepers on our team, as well as some of our back sleepers. While 5.25 inches is considered high loft, this profile isn’t excessively high and shouldn’t cause too much neck strain when you lie on your back. Stomach sleepers, on the other hand, should opt for the low-loft design. Most stomach sleepers on our team found the 5.25-inch model too thick.

Temperature control was one area where the pillow excelled during our tests. The foam may absorb and trap some heat, which is to be expected, but the GlacioTex cover effectively releases heat on contact and always feels cool. Since solid foam makes up the core, fluffing the pillow is never needed to maintain a full shape. We also appreciated the foam’s adaptive, pressure-relieving qualities.

What It’s Made of

The pillow contains one piece of memory foam. This material contours closely and responds slowly to movement, resulting in a cloud-like surface for your head and neck. We’ve rated this pillow as medium, or a 5 on our 10-point firmness scale. A cover made of GlacioTex cooling fabric encases the foam. You may remove and machine-wash the cover whenever it needs to be cleaned, but the foam should only be dabbed with a wet cloth if stains occur. 

The GlacioTex Cooling Memory Foam Pillow is reasonably priced compared to the competition, and Helix offers free ground shipping to shoppers in all 50 states. A generous sleep trial allows you to test out the pillow for up to 100 nights before deciding whether to return it for a refund or keep it. Should you decide on the latter, your purchase is also covered under a one-year warranty against material defects.

People who experience neck pain may prefer a pillow that provides both support and pressure relief. The Silk & Snow Pillow offers both and it also has a design that lets you customize the fill to get your perfect firmness and loft levels. 

How It Performed

We enjoyed how well this pillow molded to fit each of our testers’ head shapes. It conformed easily, which was particularly beneficial for the team members who experience pressure points. The shredded memory foam core absorbs and evenly disperses weight to decrease impact. 

Side and back sleepers across every weight group gave this pillow the highest possible rating, as its hybrid design provides significant support and a comfortable amount of cushioning. Stomach sleepers under 230 pounds also liked this model, though it was more comfortable once they removed some of the fill to decrease the loft and firmness levels. 

What It’s Made Of

This pillow has two chambers that each feature different fill materials. The inner chamber has shredded memory foam that provides structure and pressure relief, while the outer is made from down alternative microfiber that cushions the head and neck. The 100 percent cotton cover is soft and enhances airflow, though we did notice that the pillow retains some heat during the night. 

You can machine-wash the outer shell but shouldn’t put the pillow core in your washer or dryer. Silk & Snow is a Canadian company that offers free shipping to Canadian provinces and the contiguous U.S. There’s a trial window that lets you return your pillow between 30 and 100 days after delivery. A 3-year warranty protects against manufacturer defects.

Sweet Zzz’s Plant-Based Pillow has a down alternative fill and two-chamber construction that worked especially well for the side sleepers on our testing team. This pillow is also an excellent choice for eco-conscious shoppers and anyone who prefers an alternative to down. 

How It Performed

Side sleepers in every weight group enjoyed this pillow while they tested it in our sleep lab, and it was particularly well-suited to those under 230 pounds. It also proved supportive enough for back sleepers in all weight ranges as well as stomach sleepers under 130 pounds. 

Overall, our testers gave the Plant-Based Pillow high scores in most of our testing categories, but it performed particularly well during temperature control tests. The combination of the down alternative fill and cotton shell prevents the pillow from feeling too warm. 

What It’s Made Of

Sweet Zzz uses an innovative fill that’s made from plant-based down alternative. The pillow is separated into two sections: an inner chamber with firmer fill and an outer chamber that has a softer feel. The resulting effect kept testers’ necks both supported and cushioned. 

Together, the two sections have a medium firmness level that molds easily and bounces back to its original form fairly quickly. The entire pillow is quite durable and holds up well to abrasion, consistent use, and regular washing. 

You have up to 50 nights to try this pillow and return it for a full refund. Shipping is free to the contiguous U.S. and Sweet Zzz backs the pillow with a 1-year warranty.
