Product details:

The Nap Queen Memory Foam Bed in Box Mattress is ideal for side and back sleepers. The cradling feature of memory foam molds to the body, while the fully supportive design reduces motion transfer. A layer of Cooling Gel Visco Memory Foam delivers all of the pressure-relieving properties of memory foam with cooling gel infusion for a cooler sleep surface, letting you wake up refreshed. The CertiPUR-US certified polyurethane foam is made without harmful chemicals or heavy metals and contains low VOCs and no formaldehyde. The Nap Queen mattress is compatible with an adjustable base frame (sold separately). Nap Queen memory foam mattresses come in Twin, Twin XL, Full, Queen, King to complement any body size or type. Your mattress may take a little time (24-48 hours) to grow to its optimum size after coming out of the box. The benefits of waiting a full 24-48 hours include expansion & ventilation. Sleeping on the mattress before the 48 hours will not impact the quality or comfort of your new mattress.
