How many inches will this raise a person in a desk chair and will it retain that height?

It is 4 inches and retains height. I purchased to raise my height when sitting in desk chair for use with video camera. It works perfectly.

How do you Measure wheelchair for correct cushion

Measure the width and depth of the seat. The cushion should be an inch less, at least, the measured width. The thickness of the cushion might cause the chair height to be adjusted. The biggest problem is the cushion density. Firm can mean a cushion with little give to hard as a board.

No it will compress to fit your bottom.

Will this work in an adult power chair?

It works o.k. in a lift chair as far as size, ... it's perfect, however, the one I rec'd, although it was good in workmanship & materials, it was way too hard to sit in 24 / 7, and unfortunately I developed bed sores and had to quit using it.

perfect cushion

Excellent seat cushion. Highly recommended.

Received the seat cushion today and I must say this is exactly what I needed. So please that I have to jump on to give a review. The size is just right to cover my entire chair. It is firm and supportive, not the cushy stuff that goes flat the second you sit on it. The bottom covering also resist any sliding movement. Very please.

I made good use of it.

The cushion didn't suit my first needs. Found it uncomfortable as an auto booster seat. So I used it as a seat in a special chair I had made. Worked great. Supplier was super to work with.
