What Is an Air-Chamber Mattress?

An air-chamber mattress uses sealed air compartments as part of the support core rather than relying only on springs or solid foam.

The important distinction

In an adjustable version, the chamber pressure can be increased or decreased through a pump and control system. That makes support changeable after purchase.

What to check when shopping

When comparing designs, look beyond the word “air.” Chamber count, independent sides, zoning, pump/control design and the materials above the chamber all matter.
