This is the most uncomfortable ergo chair I've ever sat in. The back offers no support it leans back so far I feel like I'm going fall back and hit the ground. The seat has a lip that digs into the back of my knees. It's the worst. Staples return policy is only 14 days and I didn't get it put together in time to return it. Plus the box was so heavy I couldn't have gotten it into my car. Hate it! I will never buy a chair online again.
My wife has some back problems and found this chair helped her feel better over an extended work times. She did first compare chairs at the store however. Assembly was fast easy and clearly explained.
This chair is everything I wanted. It’s comfortable; the wheels are easy to move the chair; it’s easy to adjust the angle of the back of the chair. I especially like the mesh. I did sign up to have it professionally assembled - and I’m glad I did.
