Indulge your guests in the plush cooling comfort of our premium cool gel memory foam sofa bed mattress with greater cooling properties and comfort benefits than traditional memory foam. Our cool gel sleeper sofa mattress offers a generous 4.5 inches of luxurious, shape-conforming, cool gel memory foam and high density Plushfoam, made of billions of open-ended cells, resulting in a formula almost three times as dense as regular foam, and guarantees that your guests will not feel any metal bars. When our cool gel memory foam is compressed, the gel beads coalesce, resulting in a smooth shift from viscoelastic (memory foam) properties to pressure-relieving gel properties, offering a luxurious Variable Support Factor. Greater compression brings greater support and the result is superior comfort without the traditional memory foam "bottom-out" under heavy loads on a sofa mattress. Gel foam is used in many products where pressure relief and energy absorption is required. Wrapped in our luxurious breathable cover, our cool gel replacement sofa bed mattress is the perfect solution for a comfortable, cooler night's sleep.
