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 Eden Cool Adjustable Pillow is a flexible choice for anyone wanting a customized sleep experience. Its standout feature is the adjustable fill, allowing you to add or remove gel-infused memory foam to get the firmness and loft that feels best, whether you sleep on your back, side, or stomach. The pillow’s shape is a standard rectangular king size, making it compatible with most pillowcases. Its gel infusion helps keep the pillow cool by improving airflow, which is great if you tend to sleep hot.

The cover is made from a soft polyester-rayon blend called Lulltra fabric, which feels breathable and is removable for easy washing—a nice plus for freshness and maintenance. In terms of density, the pillow’s memory foam is made from new, high-quality materials ensuring consistent support without the smell or breakdown sometimes found in lower-end foam pillows. Some users might find the 8-inch loft a bit high if they prefer very flat pillows, and since the firmness is adjustable, it requires a bit of trial to find your perfect setup. Washing instructions require some care to avoid damaging the fill.

This pillow is eco-friendly certified and free from harmful chemicals, adding peace of mind about safety. Those who want a pillow that can be tailored to their exact comfort needs and value cooling and clean materials will find the Eden to be a solid pick.

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.
