I love it.  
It definitely helped with my back pain.  I’m a full time telecommuter. I had major back issues. I was seeing a chiropractor and acupuncturist.  I was in a lot of pain.  
A good chair is very important when you sit for long periods of time.  After getting this chair I was able to cut back on my therapy. 
Saves me money in medical bills. Win win for me
