Fits common chairs
The broad seat base is sized for office chairs, car seats and dining chairs with a low-profile front edge.
A contoured seat cushion that supports your lower back, spreads sitting pressure and leaves space around the tailbone area.
Support where chairs fall short
The contoured foam shape gives the hips a wider support surface while the raised back panel fills the gap many flat cushions leave behind. The tailbone cutout keeps the center of the seat from pressing straight into the body.


Desk, car or dining chair
Use Cushiva on a work chair during the day, then move it to the car or kitchen chair when you need the same support somewhere else. The compact shape keeps the seat familiar instead of bulky.
Not a flat foam pad

Long sitting comfort
The balanced foam feels stable under the hips while the breathable cover keeps the seat from feeling stuffy. It is a comfort support, not a medical device.
Before you buy

The broad seat base is sized for office chairs, car seats and dining chairs with a low-profile front edge.

The seat has a molded shape rather than a flat block, so support stays focused where sitting pressure builds.

The soft fabric cover removes for washing, useful for a cushion that follows you through daily routines.

Try it in your own chair

The back panel makes my desk chair feel more supportive without adding a big wedge.

I use it in the truck on longer drives. The cutout keeps pressure away from the tailbone area.

Firm at first, then it settles in. I like that the cover comes off for washing.

My kitchen chair was too flat. This gives it a better shape for working at the table.
Helen B.Portland, OR
The cushion stays in place and does not feel hot after a few hours.

I bought one for my office chair and moved it to the car for a road trip.
Janet L.Denver, CO
Good balance. It is supportive without feeling like a hard booster seat.
Noah P.Madison, WI
The shape helps me sit more upright and the front edge does not dig into my legs.
