YJWAN Car Wedge Seat Cushion for Car Driver Seat Office Chair Wheelchairs Coccyx Support Tailbone Pain Relief Memory Foam Seat Cushion

I'm relatively tall and heavy (17 stone/230lb/110kg and wide-ish backside), so simple/cheap cushions were little use.I sometimes sit for 2-4 hours constantly or only momentarily stand and my, otherwise excellent (and expensive), office chair's ergonomically shaped seat just doesn't have enough padding. With this cushion, I only get the same problem start around 8 hours.Fairly thick at the back, slightly slopes to a thinner front - but no sign of wear despite the chair seat underneath not being flat. Makes it comfier under your thighs on the edge of the seat (than if it was as thick at the front).The base is rubberised and pimpled, to avoid sliding around (no trouble when sitting) and the main cover material/mesh allows lots of flexing, so the material won't stretch out of shape or tear. Well stitched and constructed. I would have bought an even thicker version if available, but many reviewers are obviously lighter than me :)Has a fully adjustable elasticated strap that could stretch a chair's full width, or tighten to the stem of the back rest. Even comes in a smart zippable tube/bag you could reuse or for squeezing this small for travel.

Straps onto seat well and doesn’t move , fairly comfortable if not a little firm . Very wide so may over lap

It has a strap which fits around the back if the seat to hold it in place. Pretty comfortable, looks good and seems sturdy. I am short so the few inches gives me a better view out the window and raises me up more especially when the sun is very low in the sky, aiding good visibility.

A very good cushion for use in a car at first, but so useful that another one has bee bought to use on cafe seats, which are often hard. A good product and well made. It has not seemed to squash down after six months and is also easy to fit with the straps. Well done

Bought this for a 5hr car journey for my very uncomfortable bucket-seat Corsa. Was dreading the journey as was worried about pain & discomfort to my back - until I bought this item! So comfortable that I was able to reach my destination completely refreshed and pain-free. Item does what it says and no messing. It didn't move around and stayed nicely in position throughout the duration of the journey. A lot of the wedge seat supports are too narrow in the seat and you find yourself tipping to one side which is uncomfortable, but this one wasn't! Nice and wide and very comfy indeed! Just what I needed. Very impressed. Would buy again.

Review in 2024About a year after I got it the foam got really flattened. It still works but isn't half as good as when I first got it. This is for occassional use as a car cushion. The car is only used a few times per week for shopping mostly.Previous Review 2021The cusion is comfortable and made from modern materials. It fills in the slope of your seat so it doesn't hurt your back anymore and the result is that you arrive at your destination much more pain free and happy about things. It stays on properly and doesn't really move around very much.The cushion itself can became compressed over time though. I removed it from the cover for a while and replaced it. This did help a bit but it quickly went back to being compressed again.I accidently broke the clip on the strap after a couple of months. I emailed them and they sent a new one out free of charge. So great customer services if you get problems.Overall I would recommend this cushion.

ComfortableHas helped with sciatic pain and hamstring strain. I use it on top of a thinner cushion to make it super-soft… being larger is good - prevents the edging cutting into ur legs

It is very comfortable and great for hard chairs too
