Reasonably comfortable, price is good, you get what you pay for
Color: Black, Style: pack of 1
Easy enough to put together, moderately comfortable (though I wouldn't want to sit in it for more than a couple hours). Heads and shoulders above the other similar-looking chairs on this site. If you want a cheap chair with arms, this is pretty much the best combination of cheap and reasonably comfortable. I am using it with a spare desk/workstation, and it's fine. In fact, I plan to buy another one.
Recline is good (make sure to loosen the twisty thing. Rolls fine. Feels study enough for me. I'm 5'10", 185 lbs, and my husband is 5'9", 215lbs, and both of us feel like the chair is roomy and durable. Certainly worth it for the price.

Priced right
Color: Black, Style: pack of 1
I got this chair for the price and wanted to try something with a vented design. The instructions are simple with pictures only but seemed to work.
Pros: Decent price. Fairly good fit and finish. Assembly was easy with an exception. You get extra screw bolts. Screws appear to have Loctite.
Cons: The arm rests were extremely difficult to attach to the seat. 4 bolts. The threaded bolt holes in the seat cushion did not line up well with the holes in the arm rest even though the arm rest holes were slotted. It took major tweaking. The angles of the chair made it even more difficult to assemble unless you built a custom work bench. You get an Allen key but I used a ratcheting screw driver.
The 5 wheel base that the chair sits on required partial assembly. It comes with 4 of the arms attached as one piece normally but the 5th arm needs to be attached in sort of a keyed design. You'll need a mallet. My first thought was why? The only reason I came up with was it allows for a smaller shipping box. Smaller boxes equal more chairs shipped on the same ship from Vietnam. In any case it is a con since IMO it creates a stress point that could snap. The wheels are small and plastic. I used a set of "roller blade" style office chair wheels I already had.
It has adjustments for elevation and tilt. My wife sat in it and she says it's comfortable in her sewing room so I'm happy. Of course time will tell.
Three stars for the assembly issues. Overall: Good deal for a not so expensive chair

highly recommend
Color: Peach Pink, Style: pack of 1, Color: Peach Pink, Style: pack of 1
This chair exceeded my expectations! It was easy to assemble, feels sturdy, and is very comfortable for long hours of work or studying. The lumbar support is great, and the chair rolls and swivels smoothly. The pink color is super cute and looks exactly like the pictures. Great value for the price — highly recommend!
