As a 6-foot-3 drummer, I seem to be affected more than usual by the attendant back issues that come with driving long distances to lug heavy gear and play long gigs! So it's really important that I have a stool that I can 1) raise very very high so as not to put strain on my hips, and 2) stay completely still and not wobble at the limits of its height, throwing my centre of gravity all over the place.
After several years of spending anything up to €300 on supposed top-of-the-line thrones from various big name manufacturers, I've found the answer for a fraction of the price. It's very light and portable, and stays perfectly steady because it doesn't rely on a spindle design, and comfortably reaches the height range advertised. This last point is worth considering for any tall players looking at a hydraulic stool. The height range advertised for these is based on the stool at rest. However, when you sit on a hydraulic stool the height inevitably goes down an inch or two.
One tiny criticism for this throne: I would love if the foam padding was even a tiny bit thicker and softer.
Overall, a terrific stool for the price, and well worth a go if you're a taller drummer looking for the right stool from which to play at the correct height. Cheers!
