My back was killing me after long hours of sitting each day at work, so I ordered this cushion in hopes of finding relief. I've been pleased by the results so far. I still experience some discomfort if I sit all day without taking walk breaks, but the lumbar support provided by this product is quite good. I definitely feel less pressure on my tailbone, and I find that I'm able to walk and stand easier in my evenings after work. This cushion is easy to take with me in the office, in the car or even traveling, and I've definitely gotten a lot of use from it. I'd recommend it for anyone in search of affordable back pain relief options.
