Zoned AirFoam® boasts the same benefits as our original AirFoam®, but with new ergonomic upgrades. It's hole-punched around the shoulders, making it plusher and more flexible in this critical region. This targeted design helps sleepers adjust positions easily while heightening pressure relief. Meanwhile, zoned AirFoam® is firmer at the hips and lumbar area to prevent sinkage and promote proper spinal alignment.
