I got this to supplement the lack of cushion on my work chair. It's a bit too small for the chair itself, and it slides all over the place. It's also too squishy to be supportive; I sink into it so far that it aggrivates my sciatic nerve pain which then causes me to favor that side, which results in aggravation in my herniated disks. If you have chronic back problems, this cushion might not be right for you.My wife is wheelchair bound, and the canvas seat gets uncomfortable quickly. This pad provides comfort and at the same time offers load distribution for good support. She is quite happy to sit on it for extended periods of time. It also adds 2 inches of height to the wheelchair seat, which makes it easier for her to transfer when she needs to.I needed a chin that was more firm than foam that just compresses. But this cushion is hard and the bumps made it painful to sit on. Then I discovered this chair seat, in a cloth cover, is NOT returnable.I made a mistake by not reading the reviews before ordering. I ordered this for my father-in-law who has ALS. I was hoping it would be a nice cushion for him to sit on while bathing. I was completely wrong. This item is very hard and uncomfortable AND it is non-refundable!!! I’m very frustrated with this purchase and product.I bought to sit on for work, and it's so uncomfortable and bumpy. It's hard which makes it hard to get in a comfortable position and. by the end of the day my seats more than who using it. Keeps falling off the chair, no way to keep it on. I kept trying it again and again, hoping to break it in, but no luck.Using it in bathroom to take my time and comfortCushion is very hard for elderly population. Seller not clear about no return policy, had to search to find policyI bought this to sit on in my walk-in bath. I find it comfortable but it is not what picture shows. The picture shows a white cushion. No where does it say anything about being a wheelchair cushion. It arrived with a black mesh/plastic leather looking cover. The picture on box even shows a white cushion. I tried to start return process and it came back not returnable. I am using it as it is comfortable and protects against cold seat while tub fills up. It does say it is waterproof so I'll see how it works out. I was disappointed as I put in walk-in tub cushion and it came up in selections..Excellent quality
