Wake up on cloud nine (and not on the floor) with the AlwayzAire Air Mattress! This Twin-sized bed is durable and stays inflated all night long, offering superior comfort and support. Plus, with the Ultra-Fresh antimicrobial surface, your bed will be protected from the growth of odor-causing bacteria, mold and mildew on the sleep surface. Dual Pump: The AlwayzAire dual pump ensures that your air mattress stays inflated all night long. Internal sensors monitor the air pressure, and the pump will silently reinflate the bed as you sleep to maintain the intended firmness, so that you’ll never wake up on the ground. The dual pump system inflates the bed in just 3 minutes, reduces air loss and eliminates over-inflation. Plus, it includes a USB port for easy and convenient device charging. For best results, keep the bed plugged in all night. No power, no problem - this bed is also compatible with handheld pumps for inflation, but electrical power is necessary for the dual pump sensors to function properly. Durable Construction: This air mattress features a soft, velvet-like sleeping surface that is just as comfortable as it is durable. Drift off in comfort on luxurious wave beams, which help to maintain spinal alignment and provide contoured pressure relief as you sleep. The surrounding frame design also prevents roll-off throughout the night.
