Topped with an air cushion layer, the sleep mattress provides twice the thickness of ordinary sleeper mattresses using the highest quality materials and latest technology for maximum comfort. Self-sealing valve allows for easy inflating of the air cushion in just 25 seconds with accompanying air pump. Chambered air channels go from firm to soft with the touch of a button for individualized comfort and ergonomic support. Track arms create a clean look, and low back cushions and deep seats encourage lounging. Not surprisingly, Axis has been a customer favorite for more than a decade—and our most popular sleeper sofa, here with a comfy air cushion layer. Axis Leather 3-Seat Queen Sleeper Sofa with Air Mattress is a Crate and Barrel exclusive.
