A lot a times with memory foam chair is that they retain a lot of body heat. This mesh design is very comfortable. This is coming for a person that is sitting down at a desk for >10hrs/day.
First and foremost....I found this to align with highlights and lowlights in other reviews. If you're petite this might well be the most decent deal you'll find for a very respectable office chair. It competes with a far more expensive class of features and comforts - if you fit in it right. I've had serious neck and back problems and can't use just any old chair to work in at home. If you don't need/want a headrest you have cheaper options for a basic midback task chair...that's where the back on this will land on taller people. I'm 5'4" 130 lbs wear a ladies 6-8 US sizes. I do not have any issues with the front of the chair pressing in to the back of my legs. It's not touching and it's comfortable. Having been more full bodied in the past I'd estimate a US ladies size 12+ would be a no go in terms of the seat because the plastic side edges under the mesh seat could be under you and that would be very uncomfortable. My feet touch the floor flat on the lowest height setting. I have it a set a bit higher and use an adjustable angle footrest. If you're shorter legged than me a footrest would be an easy fix to be comfortable with the height. Lumbar hits perfect didn't change it from the setting it shipped with. I like being able to lean back and stretch my back from time to time...just the back piece moving is awesome in my book. The headrest is comfortable and the width of the armrests is perfect...not too far and not too close. Why not five stars? The mesh seat isn't as comfy as I'd hoped. It's not padded obvs so I can't really complain. I have a kinda bony butt where it meets the seat and I can feel the tension in the mesh under me it's not awful but it's not fabulous. A bit less give than in more spendy mesh chairs. It gets me to stand and stretch occasionally throughout the day though so it's ok in its own way. I'd prefer a softer armrest. I can fix that with adding aftermarket pads. I think it'll still be ok height wise after and I'm not stressed about the look. Last minor bummer is the wheelbase. The images looked like the gray chair would be partially gray and not silver over the whole thing but it's a trick of the light. It's the same cheap looking chrome color. I think the chrome on the armrest stems and the base look cheap and aesthetically it's my least favorite thing about the chair. Don't pay extra for a colored chair unless you actually want a different color mesh. Will it last forever and be passed along to my grandchildren? Not likely. Will it outlast the 5 year warranty period and buy me a while before I have to debate about investing $$$ in a really good chair again? Yup. At least I expect so. Especially for needing a new desk chair sight unseen in a pandemic I'd call this one a win.
Just got it yesterday. Assembly is not bad; as long as you usually are competent at such things you will be fine Very comfortable. I work 10 hour + and days and since I started teleworking full time the inadequacy of my old desk chair made that torture. In this chair I find I am sitting comfortably and in approved ergonomic position without having to think about it. I am no longer thinking about my chair (in a bad way) all day. FYI I am 5’5”. Not saying it only works for my size - I am only me and do not know. But for me it does work nicely.
