The smart design of the Aria Queen Inflatable Air Mattress with ConstantComfort Built-in Pump makes it the perfect sleeping solution for everyone. The inflatable bed offers three firmness settings to choose from. Simply plug in the mattress and set the dial to plush, medium or firm. The powerful integrated pump will automatically stop when it reaches your comfort preference. As you drift off to dreamland, the sensors of this smart self-inflating air mattress stay wide awake, monitoring the air pressure throughout the night. If air levels start to go down, a second pump goes to work, quietly refilling the air to maintain your chosen firmness. At 18-inches high this raised air bed will look just like your guest’s bed at home. Overnight guests who find it difficult to get down to ground level will appreciate how easy it is to get in and out of this bed.
