I use this on hard seated chairs. It makes you sit up straighter and gives you a little extra height, which is good when I use my laptop at the kitchen table. It would be better if it was a little longer.... or I was a little narrower.

Been using this on my desk chair. Helps in keeping me sit properly to avoid back pain. Bought another one which is used on the wheelchair of a family member for a more comfortable sitting.

I have been using this for a few days now and immediately felt a difference in my posture. My neck and shoulder pain have lessened too. If I knew about this product years ago then I would have gotten it then. It seems well made. The rubber and foam pieces are well placed so that the laptop and desk will not get scratched. Mind you it has some weight to it so while you can put it on your lap, it may not be comfortable for very long. I think the price is worth it especially in comparison to alike products.

I've been meaning to buy one of these things for awhile, but never did until last week. I have terrible posture, mostly from sitting hunched over at a computer, but I didn't have great posture to begin with.  I looked for a few exercises to do on YouTube for the foam rollers, and found one I really liked for helping with posture.  In 2 minutes, I felt my back straightening out.  Now of course, this is no magic fix.  You obviously need to do the exercises every day for awhile to get lasting results, but I am liking what I am seeing so far.  I did receive this product for a discounted rate, for a fair and honest review.

I use it for reading.  Very good to help with posture.  Keeps you from leaning forward.  I also raised my computer monitor on my desk.
I use it in a chair and it keeps me from bending forward and looking down.

I now have two of these. They are very functional, comfortable, and just what I needed to increase my sitting comfort. I recommend it.

This cushion  is soft and helps someone who needs to sit up straight. One's posture does improved when using this cushion to sit on.

It's great for stretching and sometimes I create a a sort of posture support wrap that keeps my shoulders back and down which feels great.  The texture is not terrible but for the posture pose, I wish it were softer so the edge wouldn't rub on my skin when I wear a tank top.  Happy with purchase, may buy a second for the posture wrap.

The stability cushion works as expected. I've not had any problems. It allows me to sit longer and with better posture.  I'm very satisfied with my purchase.

Worked great make it possible to drive my car with a wrenched lower back! Now using it in the so-called ergo office chair too. Encourages correct posture and takes pressure off lumbar region.

Like others said the back is straight but it is good for posture for some people who need the help.

This item helps me with my lower back pain so much!!!!! My only issue is it tends to inch up or down and is uncomfortable to sit in. But as a waitress I'm usually on my feet, so during my half shifts (about 4 hours) I'll wear this and it makes me look smaller and significantly reduces my back pain and improves my posture.

I needed to sit higher in my chair to reach my desk. This gives my feet a comfortable place to rest. It's on carpet so it doesn't slide too easily, yet I can scoot it around as needed to change position when I want.

Helps a lot with my back and posture and while it was not my reason for purchasing the product, it apparently has a noticeable effect on my physique as well.
