I work as a software developer and as you can imagine I spend a good amount of time sitting at a computer every day. i’ve got a degenerated disc that will give me back spasms from time to time. recently it had gotten so bad that I would work from home using my laptop laying on my back just to avoid the pain. I strech regularly which helps but sitting for long periods of time would just cause my back to stiffen up – even with getting up periodically. Looked a few of these products and purchased this one based on the good reviews. i can honestly say it’s made a night and day difference. It offers great support and is very comfortable. the strap is adjustable so you can position it higher or lower depending on what’s comfortable. I was at the point where I was worried about how I was going to get through the day sitting down but this support has changed that. I really can’t say enough about it. ..More
