Brenham Soft Hybrid Mattress Comfort and support characterize this upgraded hybrid mattress. The Sealy Posturepedic Plus Hybrid Brenham Soft features Sealy's highest coil count and a thick layer of their most premium, pressure-relieving memory foam. The result? Evenly dispersed body weight and a cooler, better night of sleep. A ventilated, reinforced edge improves breathability and durability, while the antibacterial soft knit cover is cool to the touch and keeps the mattress protected.
