The PS seating system is designed with versatility and durability in mind. The sliding, telescoping frame and expanding seat pan allow for full range of adjusment. Plus, the PS is constructed of a strong tubular material, making it a rugged option for any lifestyle. The level of adjustability on the PS system is unmatched in it's class - 5° of adjustability in the footplate, armrests that both flip up and move out of the way, and footplate hangers that swing away or swing inside when needed. For a perfect match of simplicity and function, you can't go wrong with the PS!
