Air valve adjustable height cushion for car camping. - Size: 58cm x 48cm (when expanded) / 58cm x 14cm (when stored) - Adjustment function: Height adjustable with air valve - Usage: Cushion suitable for car camping Thank you for viewing. I am selling this because I have changed cars. I used it about twice in a Step WGN before. Although there are no major stains or scratches, it is a used item, so I would appreciate it if you could purchase it only if you understand this. Online, they are often sold in sets of 4, but this time it will be sold as a 【set of 5】. By using this cushion not only in the rear seats but also in the passenger seat, you can reduce the height difference. If you put a futon on this mat, you can sleep even more comfortably. #Honda #StepWGN #HONDA #CarCamping #STEPWGN #Toyota #TOYOTA #Nissan #NISSAN #Bed #HeightDifference #Leveling
