I purchase chairs from Staples because of the seven-year warranty. The company replaces components on the chairs for up to seven years with no questions asked. It is the best deal I have found. I had another chair but the warranty expired so I bought a new one.
I picked this up today from the store and just got done building it. It is a lot smaller than I expected. For reference I am 5’4” and even on the highest setting my knees are still bent with my feet touching the ground. It’s a little comfortable but very stiff and the seat is also very small. I expected a lot better than this and I will probably be returning.
