PREUP Cushion for Coccygeal Sciatica Relief, using memory foam, Ergonomically Correct sitting posture portable Cushion, Suitable for office Chairs, Wheelchairs, Kitchen Chairs, Recliners, car seats

This is a very thick memory foam cushion, and I use it at my office chair everyday for hours! My chair previously was very hard and it caused me pain when spending too much time sitting on it and even pins and needles numbness feelings constantly. After getting this foam cushion, I am so relieved that I don't have those problems or issues anymore!The quality of the foam is very strong and it's not as soft as the typical memory foam, it's actually a bit more firmer and so can take a lot of weight from a person and won't get bent out of shape so easily. It's actually a good thing as it can support the back and spine really well and retain good posture.I really love this cushion and would love to get one for my relative which I know will benefit him a lot. Really good for the price and very happy

I bought this as I drive for a living and have it on my seat. I’ve been driving for years and it takes its tole on your back. I tried this out yesterday and I’d say after using it for a long time you will find a difference. I found it very comfortable when I first tried it and it’s very easy to sit on. Nice and soft. Time will tell so I’ll report back with update in a few weeks.

I bought this to try and improve posture and make sitting more comfortable as I'm working at home and spend a long time at a less than ideal desk setup. While it looks good in the pictures, it's literally just a shaped piece of memory foam. It doesn't promote any better posture unless you make yourself aware of slumping and right yourself (which would apply to sitting on any chair really). The only benefit it's given really is adding a bit more padding to a chair that doesn't really have enough.One thing I've noticed is that the front edge starts to compress and then you tend to slide forward. Overall, I wouldn't recommend. I'm giving it another week to see if I can get on with it any better, then it's going back for a refund.

I bought the cushion for my cab seat (I'm a bus driver) and it fits there well. It looks good and feels good. Its very comfortable. I don't know the long term benefits as yet, as I have only used it for a couple of days. However, I have to carry it up and down every day and down side is that it doesn't come with a carrier bag. If you bought it for an office or home or a personal car then you wouldn't need the carrier bag as much. Overall, Im happy with my purchase.

I had been experiencing a lot of pain in the back of my upper thigh and found sitting on my sofa, in the car and at work very painful. This cushion really supports me and has had a significant and immediate impact on the pain. Brilliant.

I use this for my canoe, open Canadian hou 14. fits like a glove, so so comfy. It's fine if you are moving around and just paddling but when it comes to fishing and I know I could be sat in the one place for a few hours at a time, this makes it so much better. Great fit to canoe seat, nice generous deep memory foam cushion, returns to its shape after you have sat on it for some time. found its also shaped to your rear and gives superb support to your coxis, also helps with the cold, keeps your bum nice and warm, bonus. The material and stitching seem of good quality and I will be buying another for my wife who occasionally comes along for the ride in fare weather :)

bought A new chair and found I was suffering with numb-bum when getting up, Figured this item would solve that problem, However this cushion was just too small for my rear end, I'm 5'11 and just under 16-stone (imperial),It came folded in half in a plastic bag, which was then placed in a amazon box which was half filled with paper, so really the cushion could of been stored unfolded and delivered normally in this box.Anyway I digress. I left the cushion to erm..expand as recommended even though there wasn't much room is the cushion cover to accommodate much of a expansion then I dropped it on my chair.First impressions were not good. Its quite thin in the grooved out parts where your legs rest and the bottom is like a smooth thin plastic/rubber material with bumps all over it (I'm guessing for some type of grip/friction attempt)My chair is like a fake leather (like most gaming chairs), The bottom did nothing to grip the material it slipped about. More importantly though the metal zip that you use to take the cover off the cushion in order to wash it comes in direct contact with my chair, I knew it would end up damaging the chair over time so I returned the cushion. (something to bear in mind if you decide to buy it).All this is subjective though and it may be good for you, It simply wasn't for me.

I was desperate to find a comfortable pillow that would prevent my head from flopping over too far to the side when lying on my back - I've strained the muscles in my neck so many times during the night! The only other pillow that seemed to guarantee success was going to cost £70 for the delight of wedging my head in what can only be described as a cushioned vice - that's the price you pay to be wrinkle-free apparently (give me strength!). Delighted with this pillow, and took very little time to adjust to it. I love the little indents at the sides also - the perfect position to place your arm when lying on your side! It does seem a little weird when trying to lie on your side at first but it's actually really comfy.
