About this product

The raised contours cradle the hips and thighs, while the cutout at the back reduces direct pressure on the coccyx. High-density memory foam gives firm support that rebounds after use.

A soft velvet cover zips off and is machine washable, and an anti-slip bottom keeps the cushion from sliding on office chairs, car seats, airplane seats and wheelchairs.

Size and fit

  • Large. 18.11 x 16.14 x 4.76 in, about 2.07 lb.
  • X-Large. 18.11 x 16.14 x 5.28 in, about 3.01 lb.
  • XX-Large. 18.5 x 16.92 x 5.9 in, about 3.47 lb, with raised side wings up to 5.6 in high and 4.4 in of center thickness.

Measure the usable width and depth of your seat and compare it to the size you choose. The cushion should not extend far beyond the seat. Colors: Black, Blue, Grey, Grey Blue, Light Blue, Light Grey, Pink and Teal Grey.

Step by step

How to use

  1. Place

    Set the cushion on your chair or seat with the U-shaped cutout toward the back.

  2. Sit back

    Sit fully on the cushion so your hips and thighs rest on the contours.

  3. Adjust

    Raise or lower your chair or car seat if needed, since the cushion adds seat height.

  4. Wash

    Unzip the cover and machine wash it when needed.

Questions

Questions, answered

Is it suitable for long sitting and driving?

It is designed to give contoured support for long hours at a desk and on the road. You may need to adjust your seat height for a comfortable position.

Which way do I place it?

Put the U-shaped cutout toward the back of the seat.

Will it flatten when I sit on it?

Memory foam compresses to fit your body, so the seated height will be lower. It recovers gradually after use, and the amount varies with body weight, sitting time and temperature. It also feels firmer in cold temperatures.

Is it a medical product?

No. It is a comfort cushion designed to spread pressure around the tailbone, hips and thighs. It is not a medical device, and results vary.

What chairs does it fit?

Most standard office chairs, car seats, airplane seats and wheelchairs. Compare the cushion size with your seat before ordering.

Can I wash it?

Yes. The velvet cover is removable and machine washable.
