How to use

Place the cushion on the chair with the contoured side up and center it so your sit bones rest comfortably on the widest part of the pad. Sit back until your pelvis contacts the rear edge of the cushion and adjust forward or backward until your knees are roughly at a right angle and your feet are flat on the floor. For car use, ensure the cushion sits stably on the seat and does not interfere with seatbelt or airbag operation. Regularly reposition the cushion and your posture during long periods of sitting to maintain the ergonomic benefit.

Usage recommendations

Use the cushion consistently during extended sitting sessions and combine it with regular standing or short movement breaks to support healthy circulation and reduce stiffness. Clean according to the manufacturer’s care instructions for the cover material and avoid placing the cushion on unstable or uneven seating surfaces.
