Key benefits Prevents sliding and improves seating stability: builtin saddle and convex bottom minimize forward sliding on slingstyle vinyl wheelchair seats without needing a rigid base. More comfortable during long sitting: PE hollow tube core provides soft, elastic support with fast rebound to reduce pressure on the tailbone. Cooler, drier seating: 3D mesh fabric creates threedimensional airflow for better ventilation and comfort. Secure and reliable: safety straps plus a nonslip bottom with silicone dripmolded antislip particles keep the cushion in place. Durable for daily use: soft vinyl cover resists wear and is easy to clean. What it does and why it matters Stabilizes posture and reduces forward sliding on wheelchair seats, lowering the risk of discomfort or unsafe positioning. Distributes pressure and cushions the tailbone to reduce pain from prolonged sitting or compression. Maintains airflow to reduce heat and moisture buildup for more comfortable extended use. Stays anchored to the chair so the cushion does not shift during transfers, movement, or repositioning. Key features Materials: 3D mesh fabric surface for ventilation; soft vinyl cover for durability; PE hollow tube core for soft, elastic support that is breathable and washable. Antislip design: silicone dripmolded antislip particles on the bottom plus safety straps secure the cushion to the chair. Builtin saddle with convex bottom: designed specifically to work with slingstyle vinyl wheelchair seats without an additional rigid base. Performance: springy, fastrebound core with good firmness to support posture while remaining comfortable. Maintenance: breathable, washable core and wipeable vinyl cover for everyday use.

Multipurpose use: suitable for wheelchair users and for use on office chairs, car seats, and gaming chairs. Supports people with tailbone sensitivity, hip rotation issues, or lower back discomfort who need a stable, cushioned seat. Typical use scenarios Wheelchair seating: attach with safety straps and place the convex bottom against the sling seat to reduce forward sliding and add breathable cushioning for daily use. Office or home workstation: use on an office chair to improve comfort during long work sessions and help relieve pressure on the coccyx and lower back. Travel or gaming: place on a car seat or gaming chair to provide added cushioning, nonslip stability, and ventilation during extended drives or play sessions.
