I love this chair so much that I bought a second one for my home office. I have back problems and this chair is Very comfortable. I bought a cheaper one and I had to returned it because it was the so uncomfortable. This chair is money well spent.
I bought this chair after I strained my lower back presumably from sitting in an ill-fitting chair while working from home these past few months. This chair is incredibly comfortable and was very easy to put together. I love the fact that I can not only tilt it back but you don't have to force it to stay back - it will stay there on its own until you lean forward or you can lock it in a particular position. No negative aspects to report yet!
