360 degree foam encasement is an added feature found in only high quality mattresses.
Memory foam mattress made of independent pocket springs with perimeter of foam blocks around the pocket springs to create a sturdy edge that responds along with the pocket springs, so you can sleep all the way to the edge of the mattress. The pocket spring unit fits snugly inside and the foam blocks connecting all four sides to create a firm perimeter support. It is the perfect combination for maximum comfort and total independence when sleeping.
The pocket springs offer great support and deliver an immediate sense of comfort and a consistent level of pressure-relieving support throughout the night.
