I went with the reviews on this purchase and this time it was a mistake... It makes my truck seat little more comfortable if positioned properly, but the cover started falling apart after 10 days of use. Now I can see the material inside which is just a cheap foam like on most cushions you can get for under 10 bucks. I know one thing for sure - It won't last much longer than few weeks in a vehicle if you drive it a few hours a day.

Returned the item as it did not help me as I had hoped. Sitting over 10 hours a day at a desk I need more "cushion"

This seat cushion never fit my butt well. It's built well, but I just couldn't get it to feel comfy in my chair.

The photo makes them seem plush and comfy, but in reality it is quite stiff and gets rather hot. Uncomfortable for long periods of time.

i found this seat to be very uncomfortable. it was way to thick with very little give. too tight and too large,. actually made my back hurt from the width. expected a lot and this just did not work for me.

I do not find the cushion very comfortable. I think the main issue is size. It is much smaller than a typical office chair so it feels like you sitting on a bunched up piece of foam. They need to make various sizes that can be matched to a specific office chair. I have not noticed any improvement in my sciatic pain issue. It is over priced.

Already getting flat and I only weigh 103 #. Needs to be thicker and more durable. Wouldn't buy again.

For a pillow that's supposed to give support to your back this pillow is way too soft. It's has no support at all and I'm sending it back.

Tried using this product in my car and found that it was more uncomfortable than using nothing. Heats up and moves.

Just flattens out too much.
