In the 1950s, Sealy partnered with leading orthopedic surgeons to develop a mattress that offered better back support, and our famous Posturepedic® mattress line was born. The concept of Posturepedic technology was to provide additional support in the center-third of the mattress, offering the hips and lower back targeted comfort. All Sealy mattresses are tested (and re-tested) beyond industry standards to ensure you purchase a bed of best-in-class quality. This includes six intensive testing phases using state-of-the-art robotics replicating everyday simulations and use, so you’ll be able to sleep soundly knowing that your mattress can stand the test of time.
