Bought this stool because mine was suddenly overcome by my weight in the middle of a gig and I dropped a good 10 inches...I never wanted that to happen again!
The thread on this stool makes that problem a thing of the past. Once it's at the height you need, just set it and away you go!
The double braced legs are very sturdy and the actual seat itself very comfortable. Small enough not to allow freedom of movement and easy transport/storage, yet strong and stable.
This will be the last throne you buy in a long time!
