SIHOO Office Desk Chair, Ergonomic Computer Office Chair with Adjustable Headrest and Lumbar Support,High Back Executive Swivel Chair (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!

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.

You've all seen pictorial instructions before, apparently drawn by a three year old, where the dimensions and shapes of the items don't remotely correspond to what you have received, and to make matters worse you've got a fourth generation photocopy, and fewer nuts and bolts than the instructions describe.I've never given a good review for instructions ..until now. I'd put off the assembly for a few days such was my dread of what was to follow, and being 'fined' by my wife for multiple expletives. But this was totally different! A clear set of instructions combining pictures with occasional helpful pointers in English, in a good quality booklet. The whole thing took 15 minutes with a further 5 for tweaking the position of the arm rests, heights and so on. The only point where I got stuck was with the word 'shim', though it was pretty obvious by process of elimination that this word meant 'washer'. I'd never heard that term before!Anyway, it would be picky to dwell on that point. 5 stars for assembly! Just amazing, totally unexpected.I'm now adding to the original review above to give my verdict on the chair after a couple of weeks' use. I find the chair very comfortable overall but it has minor faults. I was a bit worried about the lumbar support, a few people have complained about that, but I see no issue there at all. Height adjustment of chair and arm rests are independent, which is perfect. The range of movement of the back is very limited and to my mind the angle is not quite steep enough at the highest setting. In fact, I am struggling to discern any difference regardless of how much I turn the knob on the back. A slightly more upright position is needed, but it's okay.The one real dislike I have concerns the arm rests. You really want to have rotation about the axis of the rest. Your arm sits in a groove in the armrest, with a raised lip to the left and right. This is perfect if you want to tap endlessly the letter Q and the plus sign on the numeric section of the keyboard, but realistically the vast majority of your key presses are going to be more central, with your arms at an angle of 20-45 degrees relative to the arm rest. This means your forearm is pressing on the raised lip on the inner edge of the rest. If the lip were just on the outside edge it would be fine. Or if you could rotate the arm rests to be pointing slightly inwards.However, the chair overall is very good, and would be perfect with a bit more thought about the design of the arm rests and the most likely positions of the users' arms when typing.
