Gibraltar has consistently produced quality and durable drum hardware - have been using it for 20+ years. We bought this (as part of a total refurbishing of our stage and sound equipment) as drum throne for a newly acquired Roland TD20K.
It sits really well, is adjustable for almost any size and is stable. The double bracing is important for stability and that feeling of security when you sit or rock in rhythm. On the adjustability. I must admit if you sit really low or have to sit really low in order to get your knee angle at 90° or less to the floor, you may have some issues to get it low enough especially if you are somewhat taller than 180cm.
The seating material (it is not a mesh seat, but padded sponge) may make you sweat but in a well conditioned auditorium and LED lighting rather than the old style heaters, you may still be able to have a comfortable experience.
For the price, this is worth it. Get it if it fits your budget.
