With PolyAir®, there is no need to perform a hand check. Instead, the pressure is easily monitored and adjusted with the electronic manometer, which has a clear display to reduce the risk of unwanted high or low pressure. The air pressure can be adjusted with the user on the seat cushion.
PolyAir® is available in two variants: one where the air cells are divided into two groups for differentiated pressure relief and a second where all air cells are connected for uniform pressure relief. The seat cushion can be supplied in two different heights, 60 mm and 100 mm.
