Key Features
✅ Ergonomic U-Shaped Design for Instant Pain Relief
The unique U-shaped cutout suspends your tailbone to reduce pressure on the coccyx, alleviating tailbone pain, sciatica and lower back discomfort caused by prolonged sitting.

Crafted with premium high-density memory foam, this cushion retains its shape perfectly over time, providing consistent, long-lasting support without sagging. The non-slip rubber bottom keeps it firmly in place on any surface—office chairs, car seats, countertops and more—so you never have to adjust it mid-use.
