Inflatable bed

Abstract

An inflatable bed includes an inflatable body having a top sheet, a bottom sheet, and a lateral confining sheet connected to the top sheet and the bottom sheet. A covering that covers the top sheet includes at least one outer layer and an inner layer connected to the outer layer. The periphery of the outer layer is fixedly or detachably connected to the inflatable body, and the periphery of the outer layer extends to the periphery of the top sheet. The inflatable bed with the covering according the advantages that the overall structure of the covering is simple, and the covering is convenient to manufacture and low in cost. The outer layer of the covering can be conveniently connected to the inflatable body of the inflatable bed in a fixed or detachable manner, so that the covering will not slip during use and meets the need for good comfort.
