angel olson As you are shopping for your next Sealy mattress, you will notice the prominence of the Sealy Posturepedic among the company’s many mattress choices. This mattress is the company’s crowning jewel. It was created in 2006 with the help of the Orthopaedic Advisory Board. The OAB was made up of orthopaedic surgeons and other medical professionals. The goal of the Board was to help Sealy create a mattress that would give people the chance to sleep more comfortably.
