SIHOO M18 Ergonomic Office Chair, Adjustable Lumbar Support, 330 lb, Black

I've been using the SIHOO Office Desk Chair for nearly 4 months now, and I wanted to share my thoughts on this product. In the past, I had always owned executive chairs, which were comfortable but lacked adequate support. This wasn't a problem before, but over the last year, I started experiencing discomfort in my lower back and hips after sitting for extended periods of time. It seems like age is catching up with me! My previous chair was falling apart - the faux leather was peeling off and making its way around the house, and there was no padding left in the seat. Within an hour of sitting, I would noticeably sink 8 inches lower than when I started. So, it was definitely time for a new office chair that could provide better support. I spend a significant amount of time at my desk each day, so finding the right chair was a priority for me. As someone who is over 6 feet tall and overweight, I knew I needed to do thorough research before making a purchase. After reading the reviews for this chair, which were generally positive despite a few minor issues and complaints about size, I decided to take the plunge. It seemed that any concerns raised in those negative reviews had been addressed with refunds. The chair arrived well-packaged and was quite heavy. I unpacked it at the bottom of my stairs and carried each part individually to my office. The assembly process was straightforward, and all parts were included - a good sign right from the start. While an Allen key was provided, I opted to use my own tools for final tightening, just to ensure everything was secure. Attaching the wheels required a bit of careful handling, but it wasn't any more challenging than other chairs I've put together in the past. All bolt holes lined up perfectly, eliminating any need for excessive force or adjustments. The online assembly video provided by the manufacturer proved to be incredibly helpful and comforting throughout the process. Once assembled I could see the quality was very good. I had read some other reviews that said otherwise but I can't see why. I have always spent up to £200 on chairs and this is of superior quality to anything else I have owned. I suppose if you are used to £2000 chairs then this might fall a little short. The wheels glide quietly, and there is very little movement side to side, even after 4 months (remember I am over 6 feet tall and overweight). Ergonomically this chair is fantastic. At just over 6 feet tall I did find this chair a little shorter than I was used to but I did some research and took some measurements and discovered it was actually the correct height for me and I soon got used to the new position. I think all those executive chairs I have lounged around in previously had skewed my expectations. The lumbar support, again something I had not experienced before, took some adjustment to find the correct and comfortable height but once I found the sweet spot and remembered to not slouch into it, the benefit is obvious. The headrest is fine for my height but it is fully extended. The arms adjust easily and they are nicely scalloped so my arms nestle in them which is nice. The recline feature is not something I use as I mainly have the chair locked into a correct seating position but on the odd occasion I have released it I felt comfortable and secure thanks to the large wheelbase. I have also found the mesh is brilliant on hot days, far superior to real or faux leather. To sum up, I have used this chair for on average 8 hours a day for 4 months, I am tall and heavy but the chair shows no sign of deterioration at all. My back and hip issue has all but gone and I am confident that any aches and pains I do suffer from now are not chair related. I do very much wish I had ordered one of these style chairs many years ago!

This chair is perfect at the price point. It has a full range of adjustable settings to provide the right sitting position with lumber and height adjustments. Its mesh backing means no sweaty back in warm temperatures. I use this chair approximately eight hours a day when working from home with no strains on arms or back. I cannot fault it.

I have had this chair for over 4 years now. It is still strong and working. It has provided ultimate comfort this whole time (4 years) - over long gaming sessions and 8 hour Work-From-Home sessions. Back support is great, head support is great, and it does not squeak/make high pitch noises when turning. Over the last 4 years, one issue I have had, is that the arm rest cusions have been falling apart and I find sponge on my floors every so often. The second issue, is that the bolts come lose and the chair makes an annoying sound until you screw them fully back in again. Overall, quality chair that has outlasted any other chair I have had. P.S. The price is still the same as I bought it last (current price = £170 (British pounds) or $240 (American dollars).

I purchased this chair in 2020 and it has served me exceptionally well. I found it to be comfortable, great quality and is still performing well 6 years later.

I am the Editor of a scientific Journal and spend a lot of the day reading and typing on a PC. I must use an ergonomically designed computer chair that supports my back and is comfortable to use. When my old computer chair started to shed its plastic covering and created a real mess on the carpet, I researched a replacement chair. Based on the reviews on the web (YouTube) and Amazon I selected the SIHOO Office Desk Chair, Good reviews and a fair price. It arrived quickly, 2-days from Amazon. All parts were carefully wrapped and the instructions were easy to follow. Additional screws and washers were provided. A big change from the old days when at least 1 screw might be missing from a self-assembly package! Assembly was easy, using only 1 tool, a robust Alan key. I also found an assembly video on YouTube. But it was not required. The assembled chair felt solid, of excellent quality and comfortable. Adjustment was easy. The mesh back is a good feature. Plenty of ventilation. I have been using it for a week now and am pleased to recommend it.

I recently switched to the SIHOO M18 Office Chair, and I'm genuinely impressed. Putting it together was a breeze, and from the first sit, I could tell this chair was something special. Let's talk comfort – the adjustable headrest and lumbar support are spot-on. It's a simple thing, but it makes a world of difference during long work hours. The breathable mesh backrest is a nice touch, keeping things cool and comfortable. Adjustability is where the M18 shines. The armrests and height settings are easy to tweak, so you can find your sweet spot without fuss. The smooth-rolling casters are a practical touch, making it easy to move around without any hassle. Aesthetically, the M18 fits right into my workspace. It's got a clean, modern look without being too flashy. The high-quality materials make it feel sturdy and dependable. In short, the SIHOO M18 has become my go-to chair. It's simple, comfortable, and just works. If you're after a reliable office chair without all the bells and whistles, the M18 is a solid choice. I recommend it to anyone looking for a genuine upgrade to their workspace comfort.

I’ve been using this chair for about 11 months and here’s my honest take: The chair is comfortable for long hours. The lumbar support and seat height adjustments make a big difference. The mesh back keeps me cool, though the seat cushion can feel a bit rough if you’re wearing shorts (I solved this by adding a cushion cover). Overall, it feels solid with strong metal feet and a sturdy frame. However, the wheels have been disappointing—two of them popped off while I was just sitting, which really shouldn’t happen. I can reattach them, but one keeps slipping off, which raises concerns about long-term durability. Assembly was very straightforward with clear instructions. I managed to put it together without any issues. Excellent back support. The lumbar cushion and ergonomic design really help reduce strain during long working hours. Lots of options—seat height, recline, armrests, headrest, and lumbar support. It’s easy to customize the chair to your needs, although the headrest feels a little stiff once set. Value for Money: Mixed feelings. The ergonomics and comfort are worth it, but the wheel issue makes me question whether it’s truly good value after a year of use. A well-designed, comfortable chair with great support and adjustability, but the wheel problem holds it back from being a 5-star product.

Generally, the chair is well made and pretty easy to assemble. The assembly instructions are clear, the fixings are well packed and clearly marked and it is nice that they give you space screws. Another nice feature is they provide a hex driver with a plastic handle rather than the usual Allen key. The chair is on the firm side, so not really comfortable but I guess that it so that it will support better. Now the bad bits. The lumbar depth support is faulty. Turning the knob in either direction has no effect. Thee is a screw thread and it is not engaging. If you push the lumbar support gently when turning the thread will engage and the depth will adjust as you turn the knob. All looking good but no, as soon as you sit on it the thread loses grip and the lumbar depth adjustment just snaps back to unextended. Basically you can’t adjust the lumbar depth, only have it unextended. Possibly just an isolated fault on the one I got. Comfort - as I said before it is on the firm side but not to bad, but the lumbar support is horrible, really uncomfortable - even in the least extended position it feels like it is pushing too much into my back. The only way I can sit in any comfort is to push the lumbar support to the lowest position so it is not really touching my back. Headrest - or so it a neck rest - think a bit of both. Whichever it seems pretty pointless. The back of the chair is slightly tilted back even in the most upright position. So when my head/neck to contacting the head/neck rest I must admit that it is quite comfortable but this leaves me gazing up into the air, well above my computer screens and work on my rest. Nice if you want to take a snooze but when working at your desk it does nothing at all because your head is not in contact with it. Overall a little disappointed - probably going to return it. Also, I’d echo what another reviewer said - if you are tall it is not good. I’m just over six feet, not excessively tall but I find that neither the lumbar support nor the neck/head rest go quite high enough. I’ve lowered my rating because I have now had the misfortune of the SIHOO customer service. The first message explained the problem with the Lumbar Support precisely. They replied saying that they wanted photographs. Rather pointless as I had already explained that the problem with with the internal mechanism so photographs of the exterior will reveal nothing. But I complied and I sent the photographs that they requested. I have just heard back and they have said that they are going to send out a new arm rest !!! I feels like SIHOO are being deliberately evasive and obstructive. Very close to asking Amazon to intervene. The saga continues. They eventually ‘recognised’ the faulty part and said they would send one out. But not immediately, no sense of urgency, it would be dispatched in a few days time and then I would have to wait 5-7 days for delivery even though the6 claimed this was from their UK warehouse. I later checked whether it had been dispatched and was given some far-fetched story that the request was made at their OLD warehouse but they were out of stock so they have placed an order with their NEW warehouse - but none of this was done until after I waited the allotted time and chased them up. Every time I just get excuses why nothing has been done. I no longer believe that I will ever see the replacement part so will have to take this up with Amazon for return and refund. This is a terrible seller. It is one of those where if you receive a product that is fully working all will be good. But receive a faulty product, or worse have a product that develops a faulty over time then you will be faced with one of the worst and most evasive customer services that I have ever encountered.
