This is the inflatable bed that provides a superior combination of comfort, ease of use, and air retention. Its inflatable circular air coils and internal reinforcements provide support, conform to the sleeper’s body shape, and cushion pressure points. At 18" high, it is easier to get into/out of, unlike other infatable beds that sink on the side when one tries to get up. It has a built-in electric pump that inflates or deflates the bed in 3 1/2 minutes, automatically shuts off when the selected firmness setting is reached, and silently engages to maintain firmness. Folds easily for storage in the included bag. Includes a removable pillowtop mattress pad. Twin. 74" L x 39" W x 18" H. (18 lbs.)
