SIHOO M18 Ergonomic Office Chair for Big and Tall People Adjustable Headrest with 2D Armrest Lumbar Support and PU Wheels Swivel Tilt Function Black

While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best.It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete!I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up.Okay! I can live with this. It has been almost two full months of using this chair and I have no problems.Pros:easy to assemblesufficient comfort level - adequate cushion in the seatcan be leaned back or pop the lever in to stay straight uprollers on bottomheadrest is adjustableaffordableeasy to cleanarm-rests can be moved up or downheight adjustment is self-explanatory - you'll figure it outthe "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like thatOverall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough.I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.

I've been using the Sihoo M18, and it's a very solid and ergonomic chair. The chair feels incredibly sturdy and supportive, making it a reliable choice for long hours at a desk.The seat is notably firm, which is likely excellent for maintaining perfect posture and proper ergonomics. However, I've found that it can feel a bit too hard over time, which can become uncomfortable during very long periods of use. The back support is fantastic for desk work, and the headrest is a nice addition that provides extra comfort.Overall, the Sihoo M18 is a highly functional and well-built chair. It's a great option for anyone who values firm, solid support and strong ergonomics.

I bought this during Prime Days and got a good deal. I am not an expert on chairs, but I've bought about six office chairs in the last decade. These are good chairs. I would buy again.Pros:- reasonable price- comfortable for both my self and my wife- seat is large, good thigh support, and soft- adjustable arm rests, lumbar supports, head rest, and tilt stiffness - nice!- somewhat easy to assemble- the screws and parts are in a blister pack with a couple extra partsCons:- rollers do not roll as easy as some chairsAssembly notes:- as a retired tech writer, I'll give the Assembly Guide a 70% - it's all illustrations and the illustrations are not large enough - the parts labels don't always match the assembly instructions- don't forget the washers - it's hard to see in the illustrations, but most bolts use them- the casters are difficult to install into the bottom frame - use a light coat of three-in-one oil on the caster stems and they will go in easily- it is difficult to attach the chair back to the seat - put both parts on the ground and concentrate on getting one bolt in, the others will be easy to get in
