This gel memory foam mattress is slightly thicker and firmer than a traditional mattress. Gel memory foam mattress supports all parts of the body evenly and individually. The gel on your mattress absorbs excess heat while you sleep, allowing you to fall asleep more quickly. Compared to conventional mattresses, the gel coating increases the mattress's use time and makes it less prone to damage. The mattress is a total of 8 inches thick and the memory sponge is 2 inches thick. It can return to the original shape when you leave the mattress, as long as regular cleaning, the mattress will be as clean as new. The mattress is compressed into a sturdy plastic bag and protected by a cardboard box. When you need to use it, just open the plastic bag and unwrap the mattress. The mattress will return to its original shape within 6 hours. Note that it takes about 72 hours for the mattress to get rid of its odor. It includes a soft hypoallergenic cover that is washable for your convenience. Pressure relieving gel foam naturally draws heat away from the body for a more comfortable night's sleep; Beautifully detailed all around cover with four-way stretch works with the memory foam to optimize its conforming properties.
