Will this help with tailbone pain?

The central cutout is shaped to keep weight off the tailbone, and the raised rear edge supports the lower back. Many contoured cushions of this type help with sitting discomfort, but results vary by body and chair.

Does it fit a standard office chair?

At 43 by 36 cm it covers most office, dining and car seats. Check your seat depth first, since the raised rear edge takes up space at the back.

Can I wash the cover?

The cover is sweatshirt fabric, but nothing states it is removable or machine washable. Spot clean it unless the label says otherwise.

Is the foam firm or soft?

It is polyurethane memory foam with quick rebound, so it is soft enough to conform but springs back after you stand up. Heavier users may find it compresses over time.

One seat cushion. No strap, carry handle or spare cover is listed.

How much height does it add?

About 14 cm at the thickest point. That can help shorter sitters reach the floor but may put taller users too high for their desk.
