It does the job very well.
It is a simple drum throne with a pneumatic adjustment, and the price, you can't go wrong with this one.
The back rest feels nice, it rotates 360, the height adjustment is super easy and the seat is also good.
The only problem is stability... if you lean back, you may find that it is not very stable.
The trick is to put one of it's feet right behind your back, so that you always have a "brake" when you lean against the back rest.
All in all, can't go wrong with this one for the price.
