Ashley Furniture Queen Mattress Set Memory foam mattresses are a hot trend for good reason—but for some they simply get a bit too toasty for comfort. Rest easy. This 14-inch queen memory foam mattress has you covered with the cradling feel you love and temperature regulation you crave. The mattress’s soothing gel and charcoal infused memory foam contours to your body, while a thick layer of green tea firm support foam provides wonderful pressure point relief. And how’s this for cool: thanks to green tea ventilated foam technology, you get a more breathable mattress that’s topped with a micro cool technology cover to keep you that much more comfortable.
