Arm Rests are a big disappointment
Color: Onyx Black
2 weeks of use. The price seems fair for what you get. The mesh is a lower quality material and I could see it getting uncomfortable for more than a few hours sitting. It feels taut with limited cushion/give.
The arm rests are a big let down. They are firm and slick so not pleasant for planting a pointy elbow into. The biggest drawback though is the many positions the arm rest can be set to. It has forward and backward adjustments and some odd angle-in/angle-out positions. The problem is that the slightest pressure on the arm rests and they move so you really cannot put your weight on them to get up or down or to readjust your posture. The result is you are afraid to touch them, and if you do, you get a loud clicking sound as the arm rest shifts away from your pressure until it hits its final position. This is jarring and frustrating. I would recommend they remove this adjustability or make it require a lever pull instead of adjust at about 5lbs of incidental pressure. If I keep the chair, I will be sending a screw up into the arm rest to lock it into place. Note that the up and down adjustment of the arm rests are fine as that requires a lever.
The leg rest is good and works as expected.
Lumbar support works well
reclining and chair ergonomics are good.

Found a great chair
Color: Onyx Black
I'm really glad I looked around as long as I did, because this chair has been fantastic. It went together easily, all the ways it adjusts work great and are easy to figure out (even the back-tilt-lock thingy), and it's really comfortable even after a whole day in it. I am on the larger side, and haven't had a single creak out of the thing. It's very sturdy. The mesh of the seat and back are great here in the desert as well.

Has good height and back support
Color: Onyx Black
I am very happy with the chair. I did replace the wheels with new casters. Didn't even try the originals though they look sturdy because they appear to be wider than others that I have seen. The arms are a little fiddley and can move when you don't necessarily want them to. What more than makes up for those minor issues is the fact that it easily fits my long legs and has great back support. It is mesh so warmth is not an issue. I think the mesh helps with the comfort rather than being sunk into a pillow. As a bonus, there is a leg rest. I can get comfortable enough to take a nap or can watch a movie while reclined. It feels very sturdy while in that position. I weigh about 205. Happy with the chair and I would recommend it for those who have a need. Great value.

Very sturdy and comfortable for the price.
Color: Onyx Black
The chair is easy to put together and very comfortable. I like that you can adjust how easy it reclines back, and absolutely love the reclined position with the foot rest up. Kinda feels like zero gravity.
The foot rest is best when you’re in a reclined position. If you have it up while in an upright position, it’s a little awkward because it’s not much lift. Only thing I don’t like is that when it’s tucked under the seat, it takes up space (in case you like to fold your ankles under the seat - it will be in the way).
Seat is wide and comfortable short term. I needed to get a cushion as I sit on it for 12 hours a day and was getting sciatica after a while.
Rolls really smoothly. A lot of chairs don’t move as smooth because of their bulkiness, but this one is really smoothly.
Very sturdy and well made for the price. Highly recommend.

Love my chair!!!
Color: Onyx Black
Love my chair! I’m a student with rheumatoid arthritis and this has made studying much more comfortable. It has great back support, is really sturdy, and easy to use, I don’t feel like I’m going to fall when I tilt it back and use the footrest. It looks good too. It fits in well with my renovated warehouse apartment. Awesome value for the money. I bought mine on sale and it is worth every penny. Thanks!
