The ROHO Single Compartment Cushion is an air cell wheelchair cushion from the ROHO range, now part of Permobil, supplied here in the Low Profile cell height of 5.7 cm (2.25 inch). Its interconnected air cells form a single compartment, so air moves freely between the cells and the user settles into the cushion rather than sitting on top of it. This DRY FLOATATION design lets the user sink in, matching the shape of the body across the contact areas while keeping the user stable, and moves with the user as position changes, which also lowers friction and shear at the seating surface. Inflation is set through one valve using an air pump. The cushions listed here range from 40.6 to 61 cm wide and 40.6 to 55.9 cm deep and weigh about 1.1 kg.

The Low Profile cell height adds little to the seat, so the cushion can be fitted with only a small change to seat height and seated position. Air cells that move with the user suit people who shift position frequently, and setting up or checking inflation involves one valve and a pump rather than a multi-stage adjustment. At about 1.1 kg it is easy to move between chairs.
