Dual Air technology for single and multi-zone chambers allows 65 separate comfort settings for each zone, on each side of the mattress.
Tri-Zone technology allows for separate settings for the lumbar zone and the head and foot zones. This eliminates "hammocking" and provides enchanced lumbar support.
Chambers are 100% urethane (which is also used in medical settings),15 mil thick and a robust 6" height.
They are manufactured using Radio Frequency (RF) welding technology, not glued.
Urethane material is naturally anti-microbial. It is strong and odorless with excellent air holding characteristics, yet allows moisture to transpire.
Chambers will not lose pressure during the night.
