Ball Chair

I work from home and have a nice chair from Costco but have found it does not help me with my posture. I slouch and lean over and end up in contorted positions so one day I thought to get my exercise ball and use that. I used it for the day but I was only a head taller than my desk and needed some height.....like a big ball. I decided to google the internet for a big ball and came across this awesome chair! I have since put this on my " to buy list", but until then this is what I have created and am using.... my mop bucket as a base and my old ball. It works pretty well.
