M18 Ergonomic Office Chair, High Back Mesh Desk Chair with Adjustable Headrest & Lumbar Support, 330lbs Capacity Computer Chair with 2D Armrests & Wide Cushion, Tilt Lock, for Home Office-Black

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.

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 assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "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 that Overall 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 am giving 4 star because the height is not high enough for me.

J'ai reçu ma commande fin septembre, j'ai payé 159,99€ (je constate qu'elle a fortement augmenté depuis ! :-( probablement le confinement qui fait augmenter les prix pas cool du tout), j'ai donc eu tout loisir de tester cette chaise de bureau avant de laisser ce commentaire. Je suis petite (1,55 mètre) mon inquiétude était donc de me tromper en achetant un chaise de bureau trop grande pour moi et inadaptée à ma morphologie, de plus en commandant sur internet impossible de l'essayer avant achat, je ne pouvais donc pas me tromper. Après de longues recherches mon choix s'est porté sur cette chaise de bureau et je ne le regrette pas du tout, elle est géniale. Tout d'abord l'article est arrivé parfaitement emballé et bien protégé, il y a même des gants pour le montage et toutes les visseries et rondelles sont fournies en surnombre pour ne pas en manquer. J'ai "chronométré" le montage ça nous a pris 30 minutes pour la monter c'est tout simple. Après le montage il faut prendre son temps pour bien l'adapter en fonction de sa morphologie pour que tout soit bien en bonne position. La chaise de bureau est de très bonne qualité les matériaux ne sont pas "tchip" au contraire. L'assise n'est pas trop profonde (j'avais un peu cette crainte du faite de mes "petites" jambes) et très confortable, les heures passées assises en télétravail rend l'assise vraiment confortable et on ne fatigue pas après de longues heures de travail. J'adore la position lombaire à positionner de haut en bas et également en durcissant la torsion avec la molette. J'adore également la têtière que l'on peut monter et descendre mais également positionner en avant ou en arrière. Possible aussi de mettre le dossier en position "détente" pour que la chaise ne reste pas droite j'utilise agréablement cette position lorsque je suis au téléphone pour me détendre. j'apprécie la qualité alu du pied et les roulettes noires et blanches sont bien adaptées. Le seul "bémol" que je trouverai à cette chaise de bureau si je veux vraiment donner un avis complet et s'il y aurait un "défaut" à lui trouver seraient les accoudoirs qui sont parfaitement moulés pour recevoir l'avant du bras (un +) qui peuvent se régler en hauteur (un +) mais que nous ne pouvons hélas pas avancer ou reculer pour permettre de les régler à notre convenance et suivant notre position bureau (un -)... dommage mais c'est vraiment le seul petit défaut que je peux lui trouver. Je voulais vous faire partager mon avis complet et détaillé car si comme moi vous ne voulez pas vous tromper et si vous faites des nombreuses recherches à la recherche d'avis et de commentaires pour trouver LA chaise idéale alors peut-être mon avis vous sera utile dans votre choix

Before buying this I hade a racing style gaming chair which are awful and this feels much better for my lower back, the adjustable back and head rest are a big hard tho but you get used to it

Je fais du télétravail et j’ai besoin d’une chaise de bureau ergonomique et confortable. J’ai trouvé ! Elle s’est facilement assemblé je l’ai fait seule en 1 heure environ. Matériel robuste et de bonne qualité. Pour le prix c’est une chaise à envisager pour un travail à la maison sans trop de fatigue. Reste à voir si la qualité et le confort perdurera dans le temps. Je recommande!

Great quality, sturdy, comfortable. Comes with clear instructions and everything you need to assemble. Highly recommend, definitely worth the money 😊
