There is a pneumatic pull rod between the mattress and the bed body, so it is named pneumatic bed, which can easily lift the bed board and mattress, and there is still a lot of storage space below: open the bed board and store things in the storage box inside. After the bed board is closed, on the surface, the pneumatic bed is exactly the same as the general bed. It is understood that the air cushion bed can store items flexibly, which greatly saves indoor space.
