Hardcastle Black Memory Foam Seat Support Cushion

I'm using it in an office chair when I work from home, because the padding on my chair is old. Just got it today and it's pretty good, definitely not memory foam though. Will see how it holds up.

I bought this because my desk is too high and I needed a booster for my chair. This arrived much faster than was advertised, which was a pleasant surprise. It is well made and very comfortable. The colour and material also matches my chair fabric perfectly, so looks like it is part of the chair. I am very happy with it and the price is excellent, much more reasonable than other booster cushions I have seen.

Does exactly what I needed for a chair that was extremely uncomfortable, fitted around and on the chair perfectly and the strap keeps it in place really well

Husband bought it for work as he is a class 1 driver, says it is fantastic and would highly recommend.

i am happy with this product everyday nice relaxing

A great addition to my computer chair.

As the driver it does lift you up slightly higher in seat for better vision but I would like slightly longer meaning from back of seat to front. Leaves a gap. I think it would be more comfortable if it reached the front of the seat.

I've never used a memory foam item before and was a bit concerned it might lose shape quickly, but I have had it a couple of months now and am really impressed. It is just the right firmness to give support and has kept its shape brilliantly. The cover fits like a glove and is well made. It did have a slight "manufactured" aroma when I first unpacked it, but a couple of hrs airing in the garden sorted that out.I think it works better on upright chairs than sofas, as your body weight tends to squash the rear of a sofa cushion and then this support is no longer level, but it may be my sofa is just too soft and on a firmer one, this accessory would be fine.I'd say it is excellent value for money. The quality is better than I was expecting, given it is priced at the lower end of the range for such items.
