I'm a guitarist. I do a lot of theatre orchestra work and I'm fed up of being provided with rubbish chairs which do my back in, and do my bum in. This stool provides excellent ergonomic support. It's sturdy and portable. The reasons for not giving 5 stars are a) I would have preferred a cloth cover (it can get quite sweaty in the pit), and b) the cost - it is very pricey. Nonetheless, I'm glad I bought this drum throne and regard it as a good investment.
