I can't help but gush about the incredible comfort, plush softness, and unwavering durability of the SIHOO Ergonomic Office Chair. This chair is simply in a league of its own, earning every bit of its 5-star review. Let's dive into the comfort factor first. Picture this: sinking into a chair that feels like a warm, supportive embrace. That's precisely how I'd describe the experience of sitting in the SIHOO chair. The cushioning is incredibly plush, and it envelops you in a cocoon of coziness. It's like a mini oasis in the midst of a busy workday. The ergonomic design is a real game-changer, ensuring that every part of your body - from your head down to your hands - gets the support it needs. The lumbar support, in particular, is a revelation. It's like having a personal masseuse tending to your lower back, even during long stretches at your desk. And when we talk about softness, the seat material is like sitting on a cloud. The premium mesh fabric on the backrest is not just breathable; it's also gentle on your skin. No more uncomfortable sticking or sweating during those marathon work sessions. It's like a gentle breeze, keeping you cool and comfortable, allowing you to stay focused and relaxed simultaneously. Now, let's get to the durability aspect. This chair is built like a tank, but with the finesse of a luxury car. It passed rigorous tests, including the BIFMA test and that impressive 1136kg static pressure test. Translation: it's built to last. You can confidently trust it to support up to 330 lbs without a hint of strain. Plus, the assembly is a piece of cake, thanks to the straightforward instructions. Even if you're not particularly handy, like me, you'll have it set up in no time. And here's the icing on the cake: the lifetime warranty. It's a testament to SIHOO's unwavering commitment to quality. Should anything ever go amiss, you're covered for life. They'll promptly send you any necessary replacement parts, no questions asked. To sum it up, the SIHOO Ergonomic Office Chair isn't just a chair; it's an oasis of comfort and support in your daily routine. It's so comfortable and soft that you'll look forward to sitting down every day, and it's so durable that it'll be your trusty companion for years to come. With a lifetime warranty to seal the deal, this chair is an absolute must-have for anyone seeking comfort, quality, and durability in one outstanding package. I couldn't be more impressed! ... show more

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. ... show more

    • Solid construction, firm but adjustable support, striking design.
Color: Black
After 15 years of heavy use my office chair finally gave up the ghost and became irreparable. After looking at a range of chairs in the $150 to $250 bracket and reading the reviews extensively, I settled on this model for it's good reviews and for the videos posted by it's buyers. What impressed me most was the care in packaging, the inclusion of extra hardware just in case, and the detailed instructions for assembly. All parts fit perfectly, were well made with above average fit and finish for the price range, and when assembled created a fine product of striking design and ingenious function. The seat is quite firm but not unduly uncomfortable, the back is very adjustable in lumbar support and the headrest is an added luxury as is the height adjustable armrests. My only complaint is the headrest does not go high enough to suit me, but that is a personal peeve. I happen to be taller than average. Most folks will find it useful and adaptable as it can rotate in closer to the head if desired. I like the fact that the height adjustment for the seat works differently than most. You don't lift up on the lever, but rotate it to change piston height. The same lever serves as a reclining lock to keep the chair back upright or allow for two reclining positions to be set for relaxed media viewing or even napping by simply pulling it out to free the action or pushed in to lock in one of three positions. The lumbar support can be adjusted in or out via a large stylish knob on the back and has a large range of adjustment. I can see this will be a long term reliable purchase. ... show more
