We offer 3 distinct lines of adjustable bed bases, each with a limited 20 year warranty. Our Models WH1 and WH2 are available in sizes that other companies do not offer, namely Twin x 74, Twin x 84, Full x 80 and Dual Queen. With 50 years of experience our mattresses are specially made for adjustable beds. Most offer a choice of up to four firmnesses. They also carry a limited 20 year warranty. All of our mattresses are made in the USA and are fully reversible (two sided) giving them almost double the life of a no flip mattress.
