Would give it zero stars if that was an option. This Aero Bed has serious design flaws with the inflater / deflater device. It is not built in to the bed as was my last Aero Bed , but instead is a separate device that you must "attach" to the bed and hold it there until the bed is fully inflated / deflated. It is awkward and does not attach to the bed firmly and falls off so that you must use both hands to keep it attached. It is a huge job to get all of the air out manually and to fold up and store. THIS BED IS COMPLETELY WORTHLESS! I would return it in a minute, but the cost of shipping back is almost the cost of the bed.
