Gaiam - Classic Balance Ball® PVC Chair - Charcoal

Very good item for those who are concerned about their posture and overall well being when the need to sit for long periods of time is necessary..

I purchased this ball chair to increase my core and spine exercise. This is helping me strengthen my back and increase flexibility

Bought for my wife, but it is a great way to stretch. Using it more than her.

Great chair makes sitting at a desk much more comfortable
