Our plus-size mattress offers uncompromised comfort with maximum support. Its hybrid design combines a luxurious Euro topper, pressure-relieving foam, and 8-inch HDMax™ coils. So, while you enjoy the foam's gentle cushioning and contouring, the individually-wrapped springs below provide strength and stability. The Evolution Comfort+ also sleeps incredibly cool and boasts extra support around the edges—everything bigger bodies need for restorative sleep. Our deluxe 8-inch coil system features low-gauge, individually-wrapped springs and reinforced edges for maximum responsiveness and strength. A quilted Euro topper with cool, contouring foam cushions your curves, giving this ultra-supportive mattress a cloud-like surface.
