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".

It was very easy to assemble and took me 20 minutes. You can do it on your own, but it's quicker and easier with two people (the backrest weighs quite a bit and the other individual parts aren't exactly light either).

I have no complaints. Very comfortable.
