As you'd expect from the Superior Memory Foam Mattress, we've pulled out all the stops. Our no roll-together internal core of ultra-springy pocket springs are made with your choice of 2 firmness feels, as we know that one size doesn't fit all body shapes. The twin interior design of pocket springs and memory foam gives individual support from your partner which will bring you greater comfort as well as full shaping to your shoulder, hip, and knee areas. Easy care, we added flag-stitched handles for top to tail turning and air vents for additional cooler fresher feel with our smart and soft temperature control. Encased in modern stretch knit fabric, deep hand tufts combine with triple side-stitching for edge to edge support and years of superior sleep.
