The Mattress Challenge V Spring Air Back Supporter mattress features Comfort Progressions technology which marries the Total Balance innerspring with innovative Conforma Balance Extended Life foam to provide outstanding support that reduces body pressure points for a great night's sleep. Other features include the Never Turn Advantage, Foam Encased Wireless Edge, and Contour Surface Technology.
The Back Supporter mattress has a Total Balance Coil System. Rows of coils with alternating facing ends prevent any "lean" or "sway" of the coil unit. Coils are placed closer together in the center third of the mattress, which helps maintain support for your hips and lumbar region.
This mattress is so well engineered, and so well constructed that it gives you the best of all possible worlds: one sleeping surface in a mattress composed of such high-quality materials that it resists body impressions for years and never has to be turned.
Superior Sitting Edge - Our Foam Encased Wireless Edge support system features high-density foam that helps reduce side-to-side motion caused by your partner's movements. This exclusive feature helps enhance consistent comfort and stability which promotes independent sleep. Foam Encased Wireless Edge expands the usable sleeping surface by 20% and provides a firm sitting edge.
