Review: Very firm and provides good support and comfort - This is a very good booster seat for short people. It's thick and very firm and provides great support. Very comfortable when sitting on it and it doesn't smash down under your weight like other booster seats I've purchased. I like this product very much and we'll probably purchase another one. I'm short and my friend is short and when we sit at the outdoor table we feel like we're in preschool. We just needed a little lift to get us up high enough to feel like adults at the table. This works!
Review: Thick/Firm/Uncomfortable but Becomes More Comfortable and Flexible with Use - Ordered this to help me when my arthritis is flaring up and I have trouble getting out of my chair. I wanted the 3 inch but reviews were not very positive with comments about it flattening and not retaining it's shape or thickness. Reviews on the 4 inch were more positive on it retaining it's thickness . Comments also said the 4 inch wasn't necessarily comfortable for long periods of time. Definitely right on that. It gives a little when sat upon but not much. It's too high for me and I'm 5'8". Will try it for a couple of days but will probably return it for the 3 inch. Also, you will probably need scissors and a knife to open the package. I had to open the desertcart box, then the manufacturer's box, then a shipping mailing bag, then cellophane wrapping, and finally a cardboard sleeve just to get to the cushion. Good grief. If you are looking for a thick, firm cushion, this should meet your needs. It's just a little bit more than I need. UPDATE: After about a week of use, It has become more comfortable. It now gives a little when sitting on it making it comfortable but retains it shape and returns back up to the 4 inch height. In fact, I like it so much now, I probably will order more. Guess it just needed to be broken in.

### ⭐⭐⭐⭐ Finally a genuinely sturdy cushion
*by S***C on September 13, 2022*

This cushion is very sturdy and does not just collapse when I sit or lean against it. It is not a squishy plushy pillow, as so many of them turn out to be. I am using it mostly as a backrest in an old easy chair, and it helps me sit up straighter without sinking into the foam. I usually put another pillow in front of it for some softness, but since this cushion retains its strength, it stays very supportive. I realize this is intended as a chair seat, but my only wish is that it came in a more rectangular shape, for those of us who might use it to lean against while sitting up.
