OLANLY Dual-Layer 4 Inch Twin XL Mattress Topper for Back Pain, 2 Inch Gel Memory Foam Support Base and 2 Inch Cooling Pillow Top Mattress Pad Cover, Plush Pressure Relief, Deep Pocket, Grey

4-Inch Dual-Layer Comfort System Upgrade your mattress with a 4-inch total comfort design: a 2-inch gel memory foam support base plus a 2-inch quilted pillow top cover. The supportive foam layer contours to your body, while the plush pillow top adds a soft, cloud-like sleeping surface for balanced comfort. | Pressure Relief for Back, Hips & Shoulders Designed to help soften a firm or aging mattress without losing support. The gel memory foam base helps distribute body weight and cushion pressure points, making it a strong choice for side sleepers, back sleepers, and anyone seeking more comfortable spinal alignment. | Cooling Comfort with Breathable Pillow Top Gel-infused memory foam helps dissipate heat better than traditional memory foam, while the quilted pillow top encourages airflow for a more breathable sleep surface. Ideal for sleepers who want plush comfort with improved temperature comfort. | Secure Deep-Pocket Fit That Stays in Place The fitted deep-pocket skirt and 360 elastic design help hold the topper securely on your mattress, reducing shifting and bunching overnight. A practical upgrade for beds, guest rooms, firm mattresses, platform beds, and pull-out sofa mattresses. | Removable Washable Cover & Easy Setup The pillow top cover is removable and machine washable for easy care. The memory foam layer should be spot cleaned only. For best results, allow 4872 hours after unboxing for full expansion and ventilation before use.
