Chair comes with the tool needed to put together . Assembly was not that easy . Work from home a couple of days week chair is perfect for thatSeat cushion moderately comfortable but occasionally seat lowers without reason. Lumbar support also doesn’t stay up on one side. I’d return if I still could but don’t have packaging to repack and return window may have passed.Pretty easy to put together... the screw holes were a bit hard to get going.Not very adjustable so keep that in mind.. also it is very straight backed and the seat is kinda short if that makes sense. For me this is good as I tend to slouch so this helps keep me from doing that.If you are a bigger person this may be a bit shallow for you.Great overall chair. Was easy to assemble but the arms are very low. They have not adjustment and for a working chair I like to adjust chair to me not me to chair. I should have read into the description a little closerI like this chair. it's not overly complicated and I like the adjustable lumbar support. I find other chairs hit me at the wrong spot. I didn't attach the arms as they kept getting in the way with my desk. Overall happy with the chair.Easy to assemble. Solid chair for the price. Good back support, but I finf the arms too low. I knew they were not adjustable, but expected them to be a bit taller. I'm 6' 2" so maybe would be great for a shorter person.I was a little skeptical at first as I often have trouble finding a comfortable desk chair. This one exceeded my expectations. It’s one of the most comfortable chairs I have has. As an online student, finding a comfortable and supportive chair is incredibly important. This chair supports my lower back well and makes it easy to sit for extended periods of time with very little to no soreness afterwards.Easy to put together but the instructions really could do with a little more help. Overall it’s a decent chair for someone on a budget but be warned of cushion not being so comfortable. I purchased this at the time because as I said, I was on a budget. I have a issue with not much lumbar support and the cushion being a lil too firm for someone who sits long hours. Otherwise, the chair has been solid.Buena opción por el precio pagado, es cómoda y los materiales acordes al precio pagado.商品には問題ありません。デザインも良い。わがまま言うと重たいです。
