10 Best Memory Foam Pillow 2026 in the United States

The Coop Home Goods Original Adjustable Pillow is a versatile choice for those seeking a customizable sleeping experience. Its biggest strength is the adjustable fill, allowing you to add or remove memory foam to get just the right firmness whether you sleep on your back, side, or stomach. This means it can suit a wide range of sleepers. The pillow uses a blend of cross-cut memory foam and microfiber, which offers good support and softness without feeling too dense or heavy. Its loft (thickness) is about 6 inches, providing ample height that you can tweak with the extra fill included.

The Lulltra fabric cover is breathable and soft, helping with airflow to keep the pillow cooler compared to traditional memory foam pillows, which can trap heat. It's also machine washable, which adds convenience. However, the memory foam can feel firmer in cooler rooms, so some adjustment might be needed. The rectangular king-size shape fits standard large beds but might be too big for smaller pillows or cases. The pillow is CertiPUR-US and GREENGUARD Gold certified, meaning it’s free of harmful chemicals and safe for sensitive users.

If you prefer a pillow that doesn’t require any adjustments, this one requires some effort to find your perfect setup. Also, while it’s breathable, it may not be as cool as specialized cooling gel pillows if you tend to sleep very hot. This pillow is an excellent option for anyone wanting a personalized memory foam pillow with medium firmness and good breathability, especially if you value the ability to adjust loft and firmness easily.

The Coop Home Goods Cool+ Adjustable Pillow is designed to meet the needs of sleepers who value cooling and comfort. It uses a unique gel-infused memory foam combined with microfiber fill, which helps reduce heat buildup—a great option for those who tend to get hot and sweaty at night. The pillow’s adjustable loft allows you to add or remove filling to find the best height and firmness for your preferred sleeping position, whether on your back, side, or stomach. This makes it versatile and personalized.

It has a firm feel, which supports neck and spine alignment well, especially useful if you need solid support. The pillow’s rectangular shape is standard and fits most pillowcases easily. The cover is made from a mix of polyethylene and polyester, featuring a soft, cool-touch fabric with moisture-wicking properties to enhance comfort. This cover is removable and machine washable, but the inner pillow requires gentle spot cleaning, which is a bit less convenient.

The pillow’s relatively thin profile (6.5 inches long and 1.5 inches wide) might feel flatter than some expect, but the adjustability helps compensate for this. The materials are certified safe and hypoallergenic, making it a good choice for sensitive skin. If you struggle with overheating during sleep and want a pillow you can customize, this Cool+ pillow performs well. However, if you prefer a very plush or very thick pillow, or want a fully washable insert, you might want to explore other options.

The Coop Home Goods Original Crescent Adjustable Pillow is designed to offer personalized comfort through its adjustable memory foam fill. You can add or remove foam to find just the right firmness and loft, which is helpful since the pillow can feel firmer in cooler rooms. Its crescent shape naturally supports the neck and shoulders, making it a good choice for side and back sleepers who want better spinal alignment and pressure relief.

The pillow uses freshly made memory foam combined with microfiber, creating a medium-firm feel that balances support and softness. The cover is made from breathable Lulltra fabric, a blend of polyester and viscose rayon, which helps with airflow and is easy to clean since it’s machine washable. There is an initial 'new foam' smell, but it usually fades quickly after airing out.

The inclusion of extra fill lets you adjust the pillow over time, adding long-term value. This model suits those who want a customizable memory foam option with good support for side and back sleeping and who appreciate washable covers and premium, certified materials.
