This mattress features a pillowtop layer with 3D snow down alternative filling and a bamboo fabric cover. The gel-infused memory foam responds to pressure and cradles the body, while the high-density support base foam offers durability and stable support. The mattress is designed to promote airflow and regulate temperature, making it ideal for back, side, or stomach sleepers. It is easy to set up and is CertiPUR-US certified, without any substances harmful to human health. The mattress is pressed, sealed, folded, and rolled in a box, and it may take 72 hours to expand and dissipate any slight foam smell.
