Bought this item as a chair, as I was not sitting upright on a regular chair.
This ball just do it for me, I'm sitting upright and regularly moving to have the right angle at my desk to my laptop.
One back draw due to the fact that this is a plastic ball, I have to get up every so often, otherwise I get to hot - but again, makes me move around, get some coffee, file some papers.... things I might have skipped sitting uncomfortably on a regular chair.
Love the product, does exactly what I expected it to... and keeping me fitter
