Air Beds are a popular choice these days. Select Comfort™ has championed its air bed as best for all around sleep, but we believe there are instances where they would be the wrong choice. For stomach sleepers or people with a history of back pain, air mattresses can be a painful alternative. For example, when the air chambers are fully inflated, they provide the needed support a sensitive back requires. As soon as air is released from the chamber, however, the heaviest part of our body (the center) goes down first, thereby creating a 'hammocking' effect and compromising the much needed good posture. Additionally, if you cannot take advantage of the firmness variability of an airbed, why pay extra for it. We recommend you purchase a mattress with a foam core or an extra-firm coil spring inside that has comfort layers on top that include Memory Foam or Latex foam.
