This is a very sturdy stool. The back rest and seat are easily removed and the foot rest can be folded flat. The legs also fold, so it is great for taking on gigs. Keep in mind that sturdy also means heavy. I think the way the back brace was designed at an angle is kind of genius. It allows you to adjust the seat and the back rest in many different combinations. I would have rated it as a 5 if the seat had not arrived damaged (I believe the fault is with the manufacturer's packing for shipping to Sam Ash). Sam Ash sent me a second seat right away. It was pushed in, but the vinyl was not broken, so I brought to near perfect condition with a hair dryer and massage therapy on the seat top.
