10 Best Mattress 8 Inch 2026 in the United States

The EGOHOME Full Size Memory Foam Mattress is an 8-inch mattress designed to offer pressure relief and medium firm support. Made with premium memory foam, it aims to provide balanced support by absorbing and distributing body pressure evenly, which can help alleviate stress on joints and relax muscles. This makes it suitable for various sleeping positions and can benefit individuals looking for spine support and smooth blood circulation during sleep.

Additionally, the mattress is infused with green tea gel, which helps regulate body temperature, ensuring a cooler sleep experience. The special bubble hole structure of the foam enhances breathability, adding to the cooling effect. A notable feature is the memory foam's stability, maintaining consistent firmness across different temperatures and humidity levels, ensuring year-round comfort.

Certified by CertiPUR-US and Oeko-Tex Standard 100, it is assured to be free from harmful substances like fiberglass. However, at 36.6 pounds, it may be slightly heavier for some to handle when setting it up. This mattress could be ideal for those seeking medium firmness, pressure relief, and cooling properties in their sleep setup.

The ZINUS 8 Inch Green Tea Memory Foam Mattress offers a medium firm feel that suits many sleepers who want a balance between comfort and support. Its memory foam material adapts to your body shape, which helps relieve pressure and reduce joint stress, making it a good choice for those with aches or sensitive spots. The mattress includes a zoned pressure relief design, which means it provides targeted support where you need it most, a helpful feature for spinal alignment. It performs well in motion isolation, so movement on one side is less likely to disturb a partner.

Temperature regulation is improved by the natural green tea and charcoal infusions, which help keep the mattress fresh and less prone to odors, though memory foam can still retain some heat compared to innerspring mattresses. Durability looks promising thanks to CertiPUR-US and OEKO-TEX certifications, ensuring the foam and cover are free of harmful chemicals and made to last, supported by a 10-year limited warranty. The mattress is also fiberglass-free, which adds to safety and comfort.

Being only 8 inches thick, it may be less ideal for people who prefer a plusher or more cushioned feel or weigh over 500 pounds, as weight limits are capped at that level. Some users might also find the initial expansion period of up to 72 hours inconvenient. This mattress represents a solid choice for those seeking affordable, medium-firm memory foam with added freshness and safe materials, especially if you want an eco-friendlier option shipped in a smaller package.

The ZINUS 8 Inch Full Cooling Essential Memory Foam Mattress offers a medium firmness level that suits many sleepers looking for balanced comfort and support. It uses CertiPUR-US certified memory foam layers, which contour to your body to relieve pressure points and help improve circulation. The mattress features breathable Airflow memory foam and a soft, breathable cover designed to promote ventilation and prevent overheating during sleep, which is a strong plus for those who tend to sleep hot. With two layers—memory foam on top and high-density foam below—it provides decent support while maintaining a plush feel. Motion isolation is generally good in memory foam mattresses, so this model should minimize disturbances if you share the bed.

Weighing about 35.6 pounds and supporting up to 500 pounds, it’s suitable for most adults. Its 8-inch thickness makes it a good fit for those who prefer a lower profile mattress or use adjustable bed frames. The mattress is also fiberglass-free and wrapped in an OEKO-TEX certified cover, ensuring safer and healthier materials. Some users might find the medium firmness too soft or too firm, depending on personal preference, and the mattress may take up to 72 hours to fully expand after unpacking. Durability is decent given the high-density foam base, but as with many memory foam mattresses, it may soften over several years. The 10-year limited warranty provides added peace of mind. This mattress is ideal for adults seeking a cooling, pressure-relieving memory foam mattress in a full size, especially those who value eco-friendly materials and moderate firmness.
