The v7 Firm Mattress offers tighter foam compression and firmer resistance for a dense sleeping surface. Our firm mattress offers the least amount of surface give. Posturization further reinforces the mattress by focusing on areas with the most body weight. The high performance fabric cover, woven with Tencel yarn, wicks away moisture and is cool to the touch. This mattress is perfect for someone who needs a firm yet comfortable option. It delivers more comfort for less money than competitive brands.
