"Offering the ultimate in all-night comfort, the Serta Raised Air Bed with NeverFlat technology combines the convenience of a raised height design with Serta's NeverFlat pump. Featuring an integrated AC-powered dual-pump system, this bed inflates and deflates quickly thanks to its powerful primary pump. After the bed is inflated, the whisper-quiet secondary NeverFlat pump maintains a constant air pressure through the night based on the firmness setting you choose (Plush, Medium, or Firm). 35 circular coils create a comfortable sleeping surface while vertical and horizontal reinforcements allow bed to maintain shape and provide improved support and comfort as you sleep. The soft-touch flocked top provides a comfortable sleeping surface on top, while also holding your bedding in place. Durable PVC construction. Carry bag included for easy transport and storage. Inflated dimensions: 80""L x 60""W x 18""H.Manufacturer style #: 985390325.
