Essential for computer workers
Don't listen to the person complaining that this went flat, I expect that they are average height and weight for a whale. I weigh about 85KG and I sit on this thing for up to 16 hours a day as I work from home and I'm a bit of a nerd too, so I often spend my evenings at my desk after work, playing games etc so I spend waay too much time in my chair at my desk. I bought a £350 gaming chair as it actually had more ergonomic options than most of the office chairs for the same price and has integrated adjustable lumbar, tilt and recline, and 4d Armrests. It's one of the premium gaming chairs and has been great. However, the one option it doesn't have is to tilt the sitting part forward so I bought this. It makes my very expensive chair so much more comfortable. Sometimes I take it off or on to change my position, but I usually end up with it on much more, as it's more comfortable on the butt and my back and legs end up aching less. Additionally, I like to sit crossed legged on my chair quite a lot, and this raises you up just the right amount in that sitting crossed legged is also more comfortable. I've used this far more than the average user I think, and in 3 month's worth of long days every single day, the memory foam is still as good as new. After sitting on it and letting it warm up, getting up off it shows the outline of your butt where it's moulded to you, and after a couple of minutes returns back to it's original shape. You know that handprint that is typical of memory foam pictures to indicate decent memory foam? That's what happens with this cushion, except it's not your hand that leaves a print, but your backside. TLDR: Highly recommended, well worth the money and almost definitely will improve your chair and posture no matter how good a chair you already have and how good your posture currently is.

Comfy supportive seat and back cushion
I bought 2 of these wedges for my work chair, as I find it too hard to sit on and lacking back support. These wedges, although a little firm at first, do mould to your shape when sat on for a while. I found they really helped in relieving back (and bottom) ache. They're supportive and fairly comfortable. The anti slip side helps in preventing them from sliding around on the seat and the shape means you can use them in multiple seating situations. I would definitely recommend.

For me: the perfect solution
My situation is quite particular. Over the last few months, I have been spending much of the day sitting on a hard wooden chair. Yep, I know that is hardly a good idea, and I won't go into all the Whys and Wherefores of how that is so but ... this seat cushion has done wonders for my butt. The cushion is firm enough to support my weight but at the same time comfortable. Predictably, my butt was getting pretty sore to the point that even a couple of minor scabs were beginning to form. However it's now more than 5 weeks since I received the cushion and the problem has been completely resolved. I reckon my case study is a pretty good test for the effectiveness of this item, and so far it has passed with flying colours. So I happily award it five stars!

Comfortable but goes flat after a short period
I bought this wedge cushion because I suffer from Degenerative Disc Disease. It's important that the wedge lifts the position and the legs are sloped downwards. The cushion is extremely comfortable, and for the first 20min it raises me fine, but after a while it gets relatively flat. I must say, it gets back into shape very quickly. At least it keeps the chair more comfortable than it would normally be. The cover is well made and comfortable. Overall it's a good product.

Ideal after operation
This is my second wedge cushion from this seller. I use them to keep my hips above knee level after hip replacement. Ideal and excellent quality. Highly recommend.

Good for a years continued use.
Not sure what the life span of these are but it was great when new for just over one year but by the end using it comfortably on my car seat the memory foam lost its memory, is now completely flat and no longer a wedge so I'm replacing it with the same.

Very good
I am leaving this review 10 months after purchase. This booster seat is still as firm as the day I bought it. Also, despite using waterproof covers on my car seats, it never moves about. I have mobility issues, which means I am less than graceful getting in and out of the car! I find it comfortable to sit on, in fact I don't even notice it's there. I am very pleased with this purchase and would highly recommend
