I would recommend people who sitting at a computer the whole day to get one! It do helps me to make a good posture. I used to put a cushion on the backside for a waist support before find this product. My waist always pain because I couldn't keep sitting correct for a while, but this one could, it makes me have to sit upright :)
Very sturdy! Excellent support. If you have to sit at the computer, you need this! This saved my back and hip by providing firm support to my lower back. I don't have a problem sitting up straight, but I never sit back in my chair so I was not getting any rest/support where you need it the most, your lower back. I started using this while recovering from a piriformis injury and it works like a charm. I can now do my work without causing further damage to my back.
It works as described. It's made of high quality material. It's a little awkward when if you have to get out of your chair often, but it gets easier the longer you use it. It definitely gives me needed support when sitting at my desk for long periods of time.
LOVE this. It really is excellent. So easy to use and does a great job of adjusting my posture while at the computer/my desk. Fully adjustable. I really recommend.
