Sealy's PostureTech system
If you're looking for a mattress that provides targeted support, look no further than the Waltham and the PostureTech spring system incorporated in the mattress. Designed and exclusive to Sealy, this innovative take on the open coil spring system ensures that the unit targets areas of your body that need the most support, responding to pressure on the mattress surface. Because the Waltham offers medium support, we recommend this sleeping solution to those who prefer to sleep on their side. Providing cushioning to the pressure points such as the shoulders and hips, the mattress promotes healthy spine alignment all night long.
