Sitriva Ergonomic Seat Cushion
A thick seat cushion with a center cut-out that takes pressure off your tailbone, hips and lower back, so you can sit longer and get up feeling easier.
- Center cut-out takes pressure off your tailbone
- Thick, supportive foam that holds its shape
- Non-slip bottom stays put on the seat
- Works on office chairs, car seats and more
Relief where sitting hurts most
The center cut-out leaves an open space under your tailbone, while thick foam spreads your weight across your hips and thighs, so less pressure lands where it aches.
- Sit longer and get up feeling less stiff
- Supports better posture through long days
How Sitriva works
Simple design, real relief.
Center cut-out
An open space under the tailbone so you're not sitting right on the sore spot.
Thick foam
Spreads your weight evenly and holds its shape.
Non-slip bottom
Grips the seat so it doesn't slide around.
Take it to the car, too
It's light enough to grab on your way out the door. Pop it on the driver's seat for commutes and long drives, then bring it back to your desk.
- Fits most office chairs, car seats and wheelchairs
- Non-slip bottom keeps it in place
Any seat. Less ache.
At your desk. In the car. Anywhere you sit.
Office chairs
Turns a hard desk chair into an all-day seat.
Car seats
Long drives and commutes without the sore tailbone.
Anywhere you sit
Kitchen chairs, wheelchairs, bleachers, travel.

Will it fit my chair?
It fits most office chairs, car seats, kitchen chairs and wheelchairs.
Does it slide around?
No. The bottom is non-slip, so it stays in place on the seat.
Can I adjust it?
Yes. A buckle at the back lets you adjust the width of the cut-out to fit your shape.
Will it flatten out?
It's thicker than a standard cushion and made to hold its shape. Like any foam, it softens a bit with long use.
