I don't own that particular Pearl throne, but I do have another that I've been using for over twenty five years. Most of Pearls hardware is well made, including their stands and will last many years.
I do own the Roc N Soc Lunar Hydraulic throne with the saddle seat and it is very comfortable. Since I bought that, I went with another Tama throne and I also purchased the back rest for the Roc N Soc and now use it at my mixers position. The first Roc N Soc throne that I bought had a round seat, but after sitting on it for 15 or 20 minutes, it would stop the blood flow to the back of my legs because of the large diameter seat. I took it back and got the saddle seat I now have.
If you're buying the throne in person, whichever one you're interest in, just sit on it for a while to make sure that you don't have issues with it.
