The GoldenRest Passport Hi-Low Firm Mattress provides comfort and support to ensure a restful night's sleep. The memory foam mattress is made of three layers of foam for solid support paired with the soft luxurious feel of memory foam. It features a unique transfer edge, a 3" firm block of foam that runs the length of the mattress, which provides stability for safe transfers when entering and exiting the bed. The 2" top layer is GelFlex foam that helps to keep you cool while you sleep. The 2" middle layer is firmer than the top layer with great rebound to enhance the supportive feel of the mattress. The 6" base layer is made of a very firm core foam that is engineered to contour perfect to the GoldenRest Passport Hi-Low adjustable base, making sleep more comfortable than other memory foam mattress. You’ll enjoy firm, full body support that allows you to easily turn over at night and helps to maintain your mobility when transferring in and out of bed.
