Extra Firm Mattress Topper King 4-inch Memory Foam + Support Foam, Double-Sided for Sleeping, Pain Relief, High-Density Firm Mattress Topper with Removable Cover, CertiPUR-US Certified, 80" x 76"

【Dual-Sided Mattress Topper, Offering Extra Firm/Firm Options】 The double-layer memory foam mattress topper perfectly balances softness and support, helping you enjoy deep sleep. One side features soft memory foam, providing adequate body support. The other side uses support foam, which better conforms to the body's curves to relieve pain and pressure.

【Ergonomic 5-Zone Design】 - This twin mattress topper adopts an ergonomic 5-zone design to achieve real pressure relief and body support. Since various parts of the body are interconnected, we divide the product into five zones: neck and shoulder pressure relief, lumbar support, hip and thigh contouring, knee and calf pressure distribution, and foot stretching. It adapts to body pressure, providing excellent support and relaxation.

【Premium Slow-Recovery Memory Foam】 - Our twin mattress topper is made of premium CertiPUR-US certified slow-recovery memory foam. Its high-density design ensures sufficient support and extreme softness and comfort, allowing you to sleep soundly all night.

【Dual-Sided Breathable Washable Mattress Cover】 - Our innovative dual-sided mattress cover offers more matching options. It is made of skin-friendly and breathable fabric certified by OKEO-TEX. The dark gray side has anti-stain function, while the white side is versatile. Equipped with a zipper for easy removal and cleaning, as well as four adjustable corner straps to securely fix the mattress. You can freely choose which side of the core to match with your favorite mattress cover for a fresh and comfortable sleeping experience.

【Warm Tips】 - It is recommended to place the foam for 24-48 hours until it regains its original size and shape.
