Good comforting sitting pillow
Just got comfort sitting pillow. So far even though not as thick as I might have expected, it is comfortable. Your bottom feels good. Your sitting posture is improved. I think it helps to soothe legs. It's washable, has a removable cover. It's durable or firm, yet cushiony. It's a good value.

Comfortable, cool, thickness and worth every dollar!
Absolutely worth every dollar”. No paid review, no strings attached. Keep it clean and you are good to go. Fits well oversized, cool and gel-springs right back up after seating long hours. My budget was simple did not want to invest on expensive ergonomic bulky chairs, taking up space in my bedroom with a small computer set up. This two sets of gel cushions keep my back nice and straight and comfortable. The bottom chair gel-cushion has been excellent at keeping its shape and does provide excellent cushioning when sitting anywhere from 6-8 hours. The top back gel cushion-also got from Amazon and it’s absolutely a must! Chair cushion cover Easily washable, but cleans off w a chub too. If you’re looking to create a “small desk station with a nice chair” and provide yourself with comfort if have a limited budget, this is absolutely an ideal set up. Have a nice set up does not require immense expense, just the right necessities! Good support, firmness just right, well designed. The quality is very good for the price. I recently started working from home, remote more and did not want to spend an immense amount of money on chairs and set ups that would take up space in my bedroom, etc., this was just an ideal set up for my laptop and my screen. Bought the desk Amazon too easy set up.

Fits in ergonomic chairs without obstructing the benefits of the ergonomic chair
My chair at work is mess and once I came back from medical leave, I found it was too low and I couldn’t raise it. It also started to hurt the back of my thighs. I got this to help relieve the pain and it did so amazingly as well as give the chair height which I had wanted. Therefore, it solved both my issues without me realizing it would have given me height. It does not interfere with the ergonomic of the chair and I still benefit from the back support of my chair while not having to deal with pain in the back of thighs. It’s soft and comfortable to sit on.

The cushion is very good for the money.
The cushion is very good for the money; it does have a zipper on the back for removing inside content. Great for office chair use and very comfortable. Not good for automobile use. My opinion.

great for what I need it for.
The Tranquil Relax Large Seat Cushion is a solid comfort for anyone who spends long hours sitting—whether at a desk, in the car, or even on bleachers. Its a large size is versatile, fitting most chairs. The non-slip bottom is a nice touch, keeping it securely in place, and the removable cover makes cleaning easy. ✅ Pros: The Large design fits most chairs Helps relieve sciatica, tailbone, and back pressure Non-slip bottom keeps it in place Removable, washable cover ❌ Cons: Firmer than expected took me some time to get used to if you prefer very soft cushioning not the cushion for you.

Excellent Value
At first, it feels quite firm when you sit on it, but as it warms up, it conforms to your body and provides great cushioning for your tailbone. This really helps alleviate my back pain. It's easy to carry with you and can be used on any bleachers or seats you need. Additionally, it has a very durable design.

Very Comfortable.
The TranquilRelax Large Seat Cushion. Good quality. Doesn't slip around at all, and most of all, it's very comfortable. I sit in my desk chair all day, and the chair itself is in great shape except for the seat getting a little flat, and this upgrade did the trick.
