I would have given it 5/5 if it wasn't for some quality control issues that my chair has. One of the screws won't tighten no matter how much I turn. I'm assuming it's because the barrel the screw goes into is faulty (excuse me I don't know the proper terminology). Because of this the chair squeaks a bit when I first sit on it or when I shift my weight. The squeak is not annoying but it worries me that in the long run it might ruin the chair since you have to have the arm rests on it in order for back to properly stay on. (I did double check every screw and all of them are completely tighten in except for this one that won't tighten.) Putting the chair together took a lot of effort and two persons. I recommend using your weight against the chair and a wall to bring in the armrest close enough for you to properly screw the back in. I have the air cylinder about half way and after two weeks of use I felt it drop slightly a centimeter if anything. But again this raises concerns that in the long run it will give out on me. (keep in mind that I am under the recommended weight limit). Another thing that some people might not like is that the chair does not lock into place when you're laying back. So you have to use your legs or weight to be reclined. The only locking available is the upright position. Overall this is a great chair exactly what I was looking for. Plenty of space for someone wide to sit on tall enough to rest your neck. (depending on how tall you are you might want to consider buying a neck pillow) Smooth wheels and smooth rotation/revolve.
I picked this up as a big and tall chair 1 it doesn’t hold close to it’s rated capacity without constantly drooping. It was a pain to assemble too - the instructions are way off.
Very comfortable chair. Well built. Easy to put together. Make sure you realize this chair is not genuine leather but a genuine leather would be a very different price point. A very good value.
