    Good, cheap, small.
    Color: Black, Size: 21.7''D x 21.7''W*38.2''H
    The quality is better than expected for the price. Seat cushion is firm but not overly hard, wheels roll nicely, piston goes up and down smoothly, and assembly is quick and easy. The one major caveat is that it's quite small. If the user is going to be maybe 5'4 or less, it'll work (this was for a child, so it turned out great). But even on a 5'6 user, the seat is rather shallow (front to back) and the armrests are so low that your elbows won't reach unless you have freakishly long arms. If you're after a cheap office chair for brief adult use, or for kids, this is perfect. I don't know how they turn a profit given that it's a fully functional office chair, shipped from China to your doorstep, for only $30. However, if you're of average height or bigger, it's probably going to be too small for you.

    I regret
    Color: Black, Size: 21.7''D x 21.7''W*38.2''H
    A very uncomfortable chair that I owned for less than a month. The seat was broken and the particle board appeared old and reused, it was an oddly painted piece of material. It looked like someone ripped down the wall of a shack and made it the chair seat base. The seat was unstable due to the large crack throughout the entire piece of board. I am not sure how it could be returned since it is near impossible to remove the seat from the base once it is assembled. A terrible purchase that I regret. I know it is low cost, but I would suggest spending slightly more for another chair. I had to order a new chair that was only slightly more expensive so I could sit down.

    Wonderful product
    Color: Brown, Number of Items: 1, Color: Brown, Number of Items: 1
    This chair offers good lumbar support and a well-padded seat. It has a very nice and smooth rocking motion, you can loosen the tight/loose knob for reclining, and it is very comfortable to sit in while working on the computer or relaxing to watch TV. The back of the chair hits just above my neck, so the back of my head rests comfortably on the top of the chair. The color, brown, is exactly what I expected and looks professional. The height adjustment works well, it sits higher than my old chair, and I like that. It seems sturdy for the 300-pound weight recommended. I got it on Prime Day, so it was a good value for the money. It came packed well and quicker than expected. The pictures are a comparison to my 20-year-old office chair. Assembling the chair was easy, however, be sure to attach the bottom part of the chair with the tight/loose knob facing the front of the chair. It's not clearly marked on the instructions. When it came time to put the back of the chair on it would be good to have another person to hold the chair back for you to align the chair arm holes and screw in, then you should be OK but I did discover that if I had attached the arms to the back of the chair first, it would be so much easier to align them for attachment. The wheels glide very easily and will take you across the room after one push. It swivels at 360 degrees easily, almost making me dizzy. I am writing this review the same day I got the chair so I will update if I run into any issues. Otherwise, I recommend this chair.

    So far, so good
    Color: Black, Number of Items: 1, Color: Black, Number of Items: 1
    When Covid hit early 2020, I was sent home to work remotely for the first time in my working life. However, my old chair that is pictured on the right is about 25 years old and no longer has any butt cushion. It quickly became painful to work in that chair all day. I have since moved to a new state and found a remote job I will be starting soon so I decided it was time to upgrade the chair. This is a decent chair if you are on a budget like I am and you are not hard on your stuff adding premature wear and tear. For me, it has good lumbar support which I needed, and more cush for the tush! I am a proportionate 5'2" female and about 125 to 130 pounds. The seat has just enough room for my butt but I don't think I would recommend this for larger people. I would look into sizing up to the big and tall chair. Take note of the seat and back size to know what would work best for you but this chair feels small yet good sized for me only because I was able to go by the measurements of my old chair. Might even be best for you to go into an office supply store to test out chair sizes for comfort before making a purchase. Sometimes I like to sit criss-cross applesauce and this chair has a very nice and smooth rocking motion after loosening the tight/loose knob for reclining and is so comfortable for me that I may fall asleep on the job and get fired. The back of the chair hits just above my neck so I am able to tilt my head back a bit to let it rest since my upper back and neck sometimes go numb after sitting for too long. Ugh, it's just so much fun getting older!! Assembling the chair was easy until I got to step 4 to put the back of the chair on. If you have another person to hold the chair back for you to align with the chair arm holes and screw in, then you should be OK, but since I had no one to help, I had to take the seat off and lay it down. I still struggled to align the back while the arms were attached to the seat so I removed the arms from the seat and attached them to the chair back and then aligned the seat with the arms and screwed them in. Once done, I inserted the completed assembled seat, chair back, and arm attachments back onto the wheels. The wheels glide very easily and will take you across the room after one push. I am writing this review the same day I got the chair so will update if I run into any issues. Otherwise, I recommend this chair.
