I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far. I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway. I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it. The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets. Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple. The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting. It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold. I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair

Color: Pink

I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!

Good office chair for the money

Color: White

It is a good quality chair that is comfortable and aesthetically pleasing. The arms aren't necessarily big enough to hold our cat - but that's because he's fairly large by cat standards. The arm rests moving is definitely nice and provides lots of opportunities to 'setup the chair' in a way that works best for you. The instructions were relatively easy to follow (take your time and think it through to make sure you have everything 'aligned right' at first) and the chair is sturdy and holding up well.

Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1

I've been looking for a new chair to replace a cheap $30 chair i bought off of Amazon last year that had been killing my back and shoulders. I wanted something in the $150-$200 range and settled on the M18. Shipping was a fast 3 days with Prime and the box arrived in great condition. All parts were separately wrapped or in their own boxes. Came with all hardware and nothing was missing. Assembly took me a little longer then normal because i have rotator cuff injury in my left shoulder so that arm is mostly useless. The most difficult part for me was attaching the wheels to the base. Other then that it was simple. Once the chair was assembled i sat in it for the first time and started making my adjustments with the recline feature, armrest level along with the headrest. Next i reached around for the lumbar support knob and tried to adjust it but with my bad shoulder i decided to just get out of the seat and turn it around and adjust it with both hands. After spinning the chair a round to get at the lumbar knob i noticed a large crack in the plastic in the middle of the back of the lumbar plastic piece. I had not made any lumbar adjustments yet so i assumed this is how i received it. The lumbar support comes preinstalled to the backrest so it either was damaged before or during the shipping process. Either way it was damaged before being delivered to me. The lumbar support still functioned properly but it was still broken. I decided to contact Sihoo's customer support that came along with the installation instructions regarding the damaged lumbar piece. I received a reply the next day and after sending them some more info about my order and a couple pics they shipped me a replacement part which took a week to arrive. I swapped out the damaged part and after owning the chair for a week so far i am really happy with my purchase. Im about 5'10 180lbs. At its highest height level my feet reach the ground comfortably flat footed. The backrest fully covers my back and the headrest adjusts very well to sit on the back of my lower head/upper neck. The armrests only go up and down....not forward and back or tilt inwards. This is fine for me as they are grooved to fit your forearm while sitting at your desk/keyboard. The armrests are also a soft cushioned rubber material...not a hard plastic. The mesh of the backrest and headrest are good material and seem well made. The seat is very wide and the cushioning is firm which i prefer. Usually more firm cushioning seems to last longer and hold its form. The base of the chair is VERY sturdy and made of all metal. My chair is on carpet and holds its position very well. As far as recline goes you can set it to recline all the way back, half way or lock the chair in the upright position. You can also adjust the resistance on the reclining feature. So that being said im very happy with my purchase. It arrived with a slight flaw which the company corrected in a fast manor and was very polite in their customer support. I personally don't have a lot of experience with many office chairs and have never used a high end chair($500-$1000+) chair before to make any comparisons. All my chairs for the most part have been from local stores like Staples or Office Depot. Id recommend this over anything they carry in this price range....and i went and looked at their products before buying this chair as well.

SIHOO M18 chair is amazing

Color: Black, Size: Pack of 1

I purchased the SIHOO M18 Ergonomic Chair a few years ago and have really enjoyed it. It’s very comfortable and offers multiple adjustments, whether you want to recline and relax or sit upright for work. The back support is also excellent, and I haven’t had any issues with the chair at all. You can easily tell it’s high quality from the build and appearance—no creaks or noises whatsoever. I highly recommend this chair to anyone in the market for a new office chair.
