Queen size mattress topper blends comfort, cooling, and durability: it features cool gel-infused high-density memory foam that delivers a cloud-like soft feel (softness level 3 ), relieves pressure, and regulates heat for a cooler sleep climate. Its strong absorption helps keep the surface dry, dissipates odors, and adjusts temperature-safe for kids and pets-while the ventilated design boosts air circulation to soften even firm mattresses, suiting both side and back sleepers. Professionally compressed and shipped in a box, it only requires unboxing, unrolling, and 48-72 hours to fully rebound. Made of premium high-density foam that resists deformation over time, it better contours to the body for enhanced pressure relief, and is CertiPUR-US certified for added safety. Material: Polyurethane.
