bonmedico Memory Foam Seat Cushion for Office Chair - Non-Slip, Seat Pads for Coccyx Pain Relief to Support Standing - Portable Car Seat Cushion w/Handle for Lower Back Support

Very comfortable. Just the right size for my chair. Fixed the 'dead' cushion problem. Doesn't slip off the chair. Useful to have a chair seat that you can angle a little bit to adjust for the slight slope in the cushion so it doesn't slide off forwards. Appears to be good quality and should last.

So far it's very comfortable, I get dead legs in some event venues when sitting in hard plastic temporary chairs so this is very useful. It has a handle on it for easy carrying so no issues there but for those rainy nights I think I'll need to find a bag to put it in so I don't wind up getting wet when I sit on it! It might be overkill to include a carry bag with all of them though but worth pointing out to those who might be using it for something similar. When you carry it with the handle there's no protection of the surface you will be sitting on.

Was a bit suspect that this would not be worth the cost but my bottom has confirmed it was worth it. It's firm enough to not get squashed flat and support your back, but has enough give to be comfortable and it cradles my butt cheeks nicely.Edit: Having had it for a week the foam has now formed perfectly to cushion and support my butt cheeks and is even more comfortable then when I first got it

owned 6 months now and driven 9000 miles.Initially good lift in driver position but seems to have compressed over time. Given material used, I didn't reckon I would get more than a year out of it.Because isn't full width of seat, it needs constant repositioning. Again doesn't reach to front of seat so causes some pain in left thigh which is resting on it.However, it has made driving much more comfortable in general, given much better view of road, especially when parking, and helped my back.I am now investing in new seat but not getting this model for reasons above, as I'm hoping I may find something even better, but it will be 50% more expensive.

you can get shaped cushions to accommodate your bum bones ~ which although this cushion eases things considerably I am thinking if getting one of the shaped ones too!

Very happy with this purchase, it is exactly what I hoped it would be. I mostly use it in the car.The cover is comfortably warm and has a convenient carry strap and the cushion itself, is a good thickness, without being bulky.

Bought as some alternatives seemed to have a potentially uncomfortable honeycomb construction. I thought that this thickness would be best, but in practice a 3ins would have been better.

Excellent.
