I LOVED this chair and received many compliments, and referred to many people! However, after a few short months, the front bar just broke! Half of the screw is stuck in the metal bar? After searching for a comfy chair for years, (literally since a MVA in 2011), I had finally found it in the Classic Balance Ball Chair! Now, I am back to square one.
My lower back pain would cause tension to carry all the way up my spine; into my shoulders, neck and even led to tension headaches. This chair alleviates the pressure on my lower back and in turn I have less tension in my upper body. I'm so glad I made the purchase!
