Excellent chair.Just keeps getting more comfortable as I sit in it.Perfect for my back and my height.I'm just over 6'1" and this chair fits.Easy to assemble and I'm legally blind but I had no difficulty putting it together.I don't need the lumbar support at this time but it's nice to have it just in case.I'm a very happy camper.Great chair,glad I bought it.I don't love inanimate objects so I can't give it 5 stars which says "I love it".

I am finding the chair more comfortable now that I am getting used to it. I lean back all day every day and put lots of pressure on it.

I sat on it for 12+ hours a day during my studies and now use it in my home office. Very nice chair!
