The Crystal Backcare 1000 Pocket Sprung Mattress has been one of our all time best sellers containing individual pocket springs that mold to the exact shape of your body’s contour. Luxurious fillings sit to the top of the pocket spring system to give the user a luxurious sleeping surface. Pocket springs are totally independent, each in its own fabric pocket so the load on one spring doesn’t affect the one next to it. The springs provide piston-like support to each part of the sleeper’s body. The result is a spring that directly supports at the point of contact and is not affected by varying weight and body shape. This allows the pocket spring mattress to contour perfectly to your body.
