bonmedico Memory Foam Seat Cushion - Ergonomic Comfort Cushion for Driving and Office Chair - Portable Car Seat Cushion for Lower Back Support - Gifts for Women and Men

I bought it to improve my posture sitting at my desk. The memory foam is so soft that it does nothing to improve your posture. ‘Yes’ it’s comfy, but there are far cheaper alternatives if you are looking for a memory foam cushion.Stay away from this product; it’s not what is says on the label!!(...and before you ask, I weigh 75kg, I.e. not too heavy for the product.)

I have ordered three different orthopeadic cushions off of amazon, and this is by far the best one. It has proper back support, and it does not flatten over long periods of usage. It is also a great size, while others look the same size, but in reality are smaller than this one.The only downside I have experienced is that if you are wearing pants of a fabric that is rather smooth (E.g. some jeans), then you slip down the cushion gradually because the "breathable" cushion cover is so smooth. I put a cloth on top of the cushion to create friction, to avoid this.

The size and shape are good and on the face of it the depth looks good, but squashed at least to under half the depth when I sat on it. I've stuffed it with more foam, but I was disappointed that I had to do that in the first place.

I have been using this on my computer swivel chair for a while now and it remains very comfortable despite the huge amount of time I spend at the keyboard. A nice extra is that they will send another seat cover for free as a thank-you for purchasing. Highly recommended.

With this cushion I can now sit on a regular kitchen chair for a few hours at my kitchen table using my laptop, rather than retreating to my study where I have a more ergonmic office chair.

Have nothing bad to say about this product, it is exactly as described. Good quality and support, seems to ease the pain a bit. The handle is really convenient to carry the cushion around.

feel much better over time since started using it.

Great product, I use it in my car for long drives, it prolongs the time driving before my legs start to get sore
