Airbed mattresses offer unparalleled levels of customization and personalized comfort. These models are constructed with air chambers in their support cores. By adding air to one of the chambers, you can make certain areas of the mattress feel firmer. Releasing air creates a softer feel for the same areas. Most airbeds have at least two chambers – one for each side of the mattress – but some have six or more to create an even more customized feel.
