Ergonomic Seat Cushions for Pressure Relief

ProtoArc seat cushions are designed to relieve tailbone, hip, and lower back pain during long periods of sitting. The U‑shape cutout reduces pressure on the coccyx, while high‑density memory foam conforms to your body. Use it on office chairs, car seats, wheelchairs, or even airplanes – anywhere you sit for hours.

Why Choose a ProtoArc Seat Cushion?

• U‑Shape Tailbone Relief – Reduces pressure on the coccyx, helping with sciatica and lower back pain.
• Premium Memory Foam – 4.3‑inch thick, bamboo charcoal‑infused, resists flattening over time.
• Anti‑Slip Bottom – Stays firmly in place on leather, fabric, or mesh chairs.
• Breathable & Washable Cover – Removable, machine‑washable cover keeps fresh.
