Office seat cushion
Before you start
Take your sitcushion out of the package and let it rest for 48 hours before the first sit. That gives it time to reach its full shape.
Non-slip side down
The grippy base goes on your chair, so the cushion stays where you put it.
Cutout toward the back
The open end of the U points at the backrest.

Frequently Asked Questions
How should I place my sitcushion on the seat?
Place the cushion on a firm, flat seat with the U-shaped cutout facing the back of the chair, then sit all the way back so your tailbone rests over the opening. If it feels off, shift the cushion slightly forward or back until your weight feels evenly supported.
Why does my cushion feel firm at first?
sitcushion uses high-density memory foam, which needs a short break-in period to soften and adapt to your body. Start with shorter sitting sessions and increase the time gradually.
Will the cushion make my seat higher?
Yes, any cushion adds seat height. At your desk, lower your chair slightly so your feet stay flat on the floor and your elbows stay at desk level. In a car, especially in a large SUV or pickup, lower the seat if you are tall so you keep enough clearance from the roof.
Can I use it on a sofa, recliner, or soft seat?
sitcushion works best on a firm, flat seat. On soft sofas or deep recliners the foam can sink and slide, which reduces support. The non-slip base keeps the cushion in place on office chairs, car seats, gaming chairs, and dining chairs.
Will it fit my car seat?
The Car Seat Cushion suits standard sedans, hatchbacks, and compact SUVs. It is not designed for extra-deep bucket seats or bench-style truck seats. If you are unsure whether it fits your seat, email us before returning it and we will help you find the right option.
Which sitcushion is right for me?
For all-day office sitting, choose the Office Seat Cushion. For long drives and commuting, choose the Car Seat Cushion. For pregnancy, postpartum, or hemorrhoid comfort, choose the Women Donut Cushion. For post-surgery, hemorrhoid, and tailbone comfort, choose the Men Donut Cushion, which is firm and best suited to sitters around 160 lb and above.
How long does it take to get used to my cushion?
Every body is different. Most people feel more comfortable once the foam has adapted and they have built up their sitting time gradually. Good posture and regular movement breaks also make a big difference alongside your cushion.
How do I clean my cushion?
The cover is removable, zippered, and machine washable. Unzip it, wash it following the care label, and let it dry fully before putting it back on the foam.
