More features

• 【Extra Firm Mattress Topper】 This twin mattress topper is built with an extra-firm surface designed to ease lower-back pressure from extended sitting and support healthy spinal alignment. Premium high-density foam delivers targeted, non-sinking support for the lumbar area and hips. Suggested for heavier sleepers, office workers, seniors, and anyone who prefers strong back support and a truly firm feel.
• 【Pressure Relief, Better Sleep】 The top layer of 3 inch memory foam mattress topper features contoured foam that hugs your curves and helps distribute weight more evenly. That balanced support cushions pressure points while supporting a more natural sleep posture, whether you sleep on your back, side, or stomach. Get real pressure relief and smoother comfort—wake up feeling less stiff and more refreshed.
• 【Cooling & Breathable Comfort】 This foam mattress topper twin combines cooling gel memory foam, bamboo-infused foam, and a Tencel fiber cover, all designed to promote airflow. Compared with standard covers, it improves temperature regulation and wicks away moisture faster to keep the sleep surface dry and breathable. Stay cooler and drier all night, helping reduce overheating and sweaty nights.
• 【Certified Safe & 120-Night Trial】 This gel memory foam mattress topper is made with CertiPUR-US certified foam and an OEKO-TEX standard cover, and it includes a 120-night trial. Certified materials offer more confidence in what touches your skin and help create a cleaner, more comfortable sleep environment—great for families and pets. After unboxing, allow 48–72 hours for full expansion; it’s also backed by our warranty and 24/7 support for long-term peace of mind.
• 【Removable & Machine-Washable Cover】 Simply unzip and machine-wash the cover to keep your bed mattress topper clean and odor-free. Regular washing helps reduce buildup from sweat, dust, allergens, and accidental spills, supporting longer-lasting comfort. It’s an easy, low-maintenance solution for busy homes, pet owners, and keeping guest or temporary beds feeling fresh. 
• 【Anti-Slip Design, Uninterrupted Sleep】 Tired of constantly adjusting your mattress topper? A grippy non-slip bottom and four adjustable elastic straps create a secure-fit system that keeps it locked in place on your bed. This 3 inch mattress topper works with most mattress types—memory foam, hybrid, or innerspring—helping prevent sliding and bunching. Spend less time re-adjusting and more time sleeping.
