Memory Foam Seat Cushion with Coccyx Cutout for Chair

Most chairs, whether at a desk, in a car, or on public transport, are not designed for extended sitting. They distribute weight unevenly, put direct pressure on the tailbone and coccyx, and offer little support to the lower back. After a few hours, that pressure becomes noticeable. After a full day, it tends to stay with you into the evening.

A well-designed seat cushion addresses this by redistributing weight more evenly across the sitting surface and lifting the tailbone clear of direct contact with the chair. Memory foam does this naturally by conforming to the shape of the body and returning to its original form between uses, so the support remains consistent rather than compressing flat over time.

This cushion uses a U-shaped coccyx cutout to relieve pressure on the tailbone while supporting the surrounding area evenly. It fits over any chair and works equally well in a car seat during longer drives. The Advanced version uses bamboo charcoal-infused memory foam, which absorbs moisture and reduces odour buildup during extended use, alongside a magnetic-closure cover for a cleaner finish.

What it does

• U-shaped coccyx cutout relieves direct pressure on the tailbone during prolonged sitting
• Memory foam distributes body weight evenly and conforms to the seated position without flattening over time
• Supports healthier sitting posture by raising and levelling the seat surface
• Fits office chairs, car seats, dining chairs, and wheelchair seats
• Advanced version: bamboo charcoal-infused foam absorbs moisture and reduces odour. Magnetic cloth cover included.

What it is made of

Memory foam with a removable, washable cover. Available in four styles from Basic to Advanced. The Advanced version includes bamboo charcoal-infused foam and a magnetic-closure cover. Non-slip base keeps the cushion in place on any seat surface.

This will work for you if

• you spend long hours seated at a desk or driving and feel the discomfort building in your lower back or tailbone
• your current chair lacks adequate cushioning or support for extended use
• you want a portable solution that moves between your desk and car without fuss

This may not be for you if

• you need a full ergonomic chair replacement rather than a cushion supplement
• you prefer a firmer, gel-based cushion rather than memory foam
