UPDATE: less than a year later, the tension that holds the back of the chair up BROKE. I sat down and heard a crack, now the chair back just falls backwards. Doesn’t hold itself up! :( i loved this chair but it only lasted a year?! Such a bummer.... now the wheel casters have fallen off and it doesn't roll. The seat sits crooked at all times, its a MESS. The only reason I am still sitting on this pile of spare parts is cause I am doing in DEPTH research for my next chair. This ones cute and comfy, but only for MINIMAL use. If used regularly it will break in less than a year... =/This chair was kinda pricey. But i love it.Tension knob range is wide. It can be set very loose or very tight. When its set loose, you sort of fly back when you lean back, but if its tightened, its the perfect amount of tension to lean back comfortably. Only the back moves. The whole seat rocks a little, but the back leans mainly.I work from home all day, this Chair is comfortable enough for this purpose... though there is a crease in the middle of the seat that’s noticeable. Other reviews mentioned this as well.Its not meant for the big and tall. Whatsoever. I am 5’2” and it’s perfect for me. My bf is 6’0” and it works for him, but i would say go with something else if you are taller/larger.Back of the seats perfect for my size. My head hits exactly on the head rest. Head rest is comfortable enough to lean back and take a nap on lunch breaks, there are some wrinkles in the hesd rest portion though.It does not have a wide range for height of the chair overall. Only about 3 inches between the highest and lowest points. Not an issue for me, fits perfectly (at the highest setting) Under my autonomous L shaped sit/stand desk when its lowered all the way.Overall, live for the look. Its comfy enough for me and the reclining mechanism was exactly what i needed for breaks. Would 100% recommend.
