This drum throne fixed my lower back. As a satisfied customer, need I say more? My old throne was a plain Pearl one, and I was limited to playing around 45 minutes at a time because of aches and pains.
With this throne I can sit higher, and the backrest automatically keeps me relatively straight, which has become natural over just a few months.
It's rather weighty and wide-legged, which is great for stability. The cushion is pleasantly firm, and doesn't seem to get uncomfortably hot either, so it's magical too.
In conclusion, yes it's expensive, but in my case it's indispensible, and it will probably outlive me. Great piece of hardware.
