I bought this throne about 2 months ago, because my old throne wasn't steady, and my back was hurting after 3 hours of rehearsal.
Pros:
I've been using the Gibraltar throne ever since I got it. It is perfect for my taste. It is perfectly steady, no movement can be noticed when you sit on it. It holds like a rock. And my back is ever so grateful.
It is as huge as my snare, and it is very comfortable. I feel like a king in the saddle. I've tried raising it to the highest position possible, still holds like a rock. I'm very proud of this purchase.
Cons:
Honestly, I can't find anything faulty with this throne.
In ONE SENTENCE: I love it, worth every cent :)
