Bests & Worsts Reviews from Amazon

The cushions are 2 1/2" thick and are filled with a stiff pad that is perfect for a kneeling chair. The wood frame is 1 1/2" oak that is finished very well. The frame "legs" are 1 3/4" rounded oak and come attached to the frame. The casters are plastic with a bolt end that you screw into metal inserts in the legs. The center brace, that goes from the bottom knee support frame to the top seat frame, is actually the height adjustment mechanism which is made out of thick metal and is covered with a 2 piece hollowed out oak dowel. It's basically a very large bolt with a threaded cap on both ends. One cap is attached to the top frame and the other is attached to the bottom frame. If you want the chair higher, turn the metal ring (which is the center of the bolt) counter clockwise. As you make the seat higher, the frame pivots at at the center point. Which means not only will the seat get higher, but it will also draw the cushions closer together and at a greater pitch. It works well and makes this chair very solid. It comes with all the hardware you need. The instructions are not the best but you can figure it out. The weight limit is 200 lbs. And it is made in Taiwan.
