MAY® continues patented innovations, advancing both Posto Series and Contour Hinge technologies with new ABS-AR (Articulating Back Support-Auto Release). ABS-AR, like its ABS predecessor, enhances all the wellness features and benefits along with redistributing unwanted weight off of players shoulders, resulting in unprecedented comfort and freedom while promoting proper posture. The Auto-Release feature is designed to allow rapid mount and dismount without loosening any of the ABS sizing or Contour fit adjustments.
