Enjoy a medium-firm feel that is luxuriously soft with the Wellsville 11″ Memory Foam Mattress. Featuring three layers of foam, you will get the pressure point relief, temperature regulation, and support you need. It all starts with the ultra-plush 1.5-inch top layer that supports and aligns the spine for all-night comfort. The second layer is plush gel-infused air memory foam that dissipates heat while you sleep. And the 7.5-inch high-density base foam layer keeps the mattress feel medium-firm while adding structure and support. Our sophisticated double jacquard cover offers a cushioned air layer that improves breathability, softness, and style. The memory foam in this product is independently tested, CertiPUR-US certified, and free of harmful chemicals. Wellsville confidently stands behind the Wellsville 11″ Gel Memory Foam Mattress and protects it with a 10-year warranty against manufacturer defects. This mattress is vacuum-packed and shipped in a box for easy transportation and setup. To decompress, simply take the box into the bedroom and place it on the bed frame. Take the rolled-up mattress out of the box and remove the protective wrap. Then watch as it expands. Available in California King, Split California King, King, Queen, Full, Twin XL, and Twin sizes.
