The Sitvana Seat Cushion
The Sitvana Seat Cushion
Support first. Comfort that lasts.
Every cushion I tried failed the same way: comfortable for ten minutes, then flat, and back to the hard seat underneath. After years of that, I stopped shopping and built the one I needed: something that holds you up instead of letting you sink.
- Ergonomic U-shaped design with a tailbone cutout that keeps pressure off your tailbone
- High-density memory foam that holds its shape under you
- Light and portable, about 1.5 lb, for the car, the plane, the office and the dinner table
- Non-slip base and a breathable, machine-washable mesh cover
Free US shipping. Try it for 30 days. If it's not right for you, send it back.

I couldn't find a cushion that held up. So I made one.
Years of buying pillows that went flat taught me one thing: soft isn't support. Sitvana is the fix I wish I'd had.
