This throne is EXTREMELY sturdy. It is built like a tank. The seat is very soft and it is very comfortable sitting on it for long periods of time. The seat can also swivel if the wing nut at the top is loosened. There is also a handy memory lock. In my opinion, this thing is almost over-engineered. Great throne for the price.
The 9600 foundation of this throne is rock-solid. The vinyl seat lets out a lot of air when you first sit sown but settling in only takes a second or two before you're ready to go. Once locked in place, save the seat rotation, this thing is an immobile, sturdy platform from which to rock. It's obvious this beast will last for a long time.
