The Mid-Rise Premium Comfort™ Twin Airbed provides amazing durability and lasting comfort. The secret is in the Fiber-Tech® beam construction, which is comprised of thousands of high-strength polyester fibers that provide enhanced comfort, stability and support. Each bed is covered in plush flocking that is soft to the touch, and the horizontal air chambers provide added stability and support around the entire bed. It is easy to inflate with the built-in internal AC electric pump, which does its job in 2 minutes.
