Seat cushion

coccyx positioninglumbar supportsupport

Overview
This set combines a U-shaped seat cushion and an extended lumbar cushion to improve comfort during prolonged sitting. The seat cushion reduces direct pressure on the coccyx while the lumbar cushion supports the natural curve of the lower back, providing a more stable and comfortable seating position for office, car or home use.

Main features & benefits

• Pair: U-shaped seat + extended lumbar for pressure redistribution and lower-back support
• U-shaped seat cushion: reduces pressure on the coccyx when seated
• Extended lumbar cushion: supports the lumbar curvature to limit lumbar slump
• 3D mesh breathable cover: fresher daily sensation
• Adjustable straps: secure attachment on most seats (maximum strap length: 130 cm)
• Non-slip base: improved stability on the chair
• Versatile use: office, car, home, travel
• Quick installation: fits in seconds

Use and benefits
The seat cushion offloads the coccygeal area to reduce direct pressure. The extended lumbar cushion supports the lower back and limits lumbar collapse. Together they improve pressure distribution and posture control to make prolonged sitting more tolerable.

Who is it for?

• People working seated (office, telework) with lumbar fatigue
• Drivers seeking more comfortable seating on journeys
• People who need better pressure distribution around the pelvis/coccyx

Installation (office & car)

• Place the U-shaped seat cushion on the seat with the opening oriented under the sensitive area.
• Sit back fully on the seat so weight is distributed to the sides of the seat cushion.
• Position the extended lumbar cushion in the lower back hollow, just above the pelvis.
• Attach and adjust the straps so the lumbar cushion does not slip. Adjust lumbar position 2–3 cm if needed to find optimal support.
