Product description

1. Extra-Large Full-Seat Coverage for More Room to Sit: The 19.7 in wide x 18.1 in deep x 5.5 in thick seat cushion provides a broader support area for the buttocks and thighs, helping reduce edge overhang and concentrated pressure. The matching back cushion measures 19.7 in high x 18.9 in wide x 2.2 in thick. This full ergonomic seat cushion and office chair back support set is designed for adults who want more coverage than a narrow or thin chair pad.
2. High-Density Memory Foam Balances Cushioning and Support: Made with high-density, high-resilience memory foam, the ergonomic memory foam seat cushion conforms to body contours while maintaining stable support during extended sitting. Contoured molding and a temperature-controlled curing process help the foam retain its shape and rebound over time, creating a more balanced feel for users who find ordinary cushions too firm, too soft, too thin, or quick to flatten.
3. Ergonomic Contour with Tailbone Cutout for Pressure Distribution: The U-shaped rear cutout creates open space around the tailbone area to reduce direct contact with the seat, while the sculpted surface supports the hips, buttocks, and thighs and helps distribute body weight more evenly. This ergonomic office chair seat cushion encourages a more stable pelvic position and natural seated posture during desk work, gaming, studying, driving, or other long sitting sessions.
4. Seat and Lumbar Support Set for Extended Sitting: Coordinated seat and back cushions provide multi-zone support for the buttocks, pelvis, lower back, and back. The full back support pillow follows body contours and upgrades existing office, desk, computer, gaming, or home chairs. Suitable for office workers, programmers, remote workers, gamers, designers, creators, customer service teams, accountants, administrators, security staff, dispatchers, and other seated professionals.
5. Dual-Strap Non-Slip Design with Breathable Washable Cover: Two adjustable back straps help secure the lumbar cushion while the rubberized non-slip base helps keep the seat pad in position, reducing sliding and repeated readjustment. The soft cotton cover uses breathable fabric to promote airflow during long sitting sessions and is removable for hand washing or machine washing, making this office chair cushion with lumbar support easier to keep fresh and maintain for everyday use.
