JIOABL Queen Size 3 Inch Cooling Gel Memory Foam Mattress Topper for Relieve Back Pain, Ventilated Design, CertiPUR-US Certified, Removable Plush Cover

This JIOABL gel memory foam topper shapes to your body for even weight distribution, easing pressure and improving sleep comfort. It's an affordable way to refresh an old mattress, soften a too-firm one, or extend your mattress's life, saving money versus buying new. The soft, breathable polyester cover has elastic straps and a non-slip bottom to stay secure. It features a sturdy zipper for easy removal and machine washing. The gel foam is CertiPUR-US certified, meeting strict safety, low emission, and durability standards. After unpacking, let the topper expand fully for 48-72 hours in a well-ventilated area; warmer rooms help it expand faster.
