Great seat - the arm rests are not sturdiest. Very comfortable otherwise. Easy to assemble.

It has good quality, can support heavier individuals, and is easy to use while providing great back coverage. The material is flexible and durable. However, the handle could be improved, as it’s not covered with soft material. Despite that, the handle is acceptable, and overall, the product has great quality.

This chair is strong, it handles my hefty weight easily. It's amazing for my back. So comfortable even for prolonged time spent at the desk. It looks nice too. This chair is of impeccable quality and I'm thoroughly pleased.

Super Heavy Duty and absolutely gorgeous office chair. I love how pretty much EVERYTHING is adjustable and it's incredibly comfortable. It looks sleek and SOOO good in my office. The arms are the best part, how they can be folded away.

After 5 years, my old gaming chair from the lockdown pandemic era had seen better days—both aesthetically and in terms of its so-called "ergonomic-ish" cushion. I was legit having all kinds of pains, and mind you I'm still fairly young-ish. Gaming chairs aren't exactly known for great ergonomics though so that was my fault, but I decided it was finally time for an upgrade.After researching, I landed on this chair and the brand due to some raving reviews out there, especially on youtube. Assembly was mostly straightforward, but I did run into some quality control issues. The stainless steel legs didn’t push in easily, and I had to use a rubber mallet to align the screw holes properly. The wheels were another challenge—one went in smoothly, but the others refused to budge, even with my best effort (and trust me, I lift heavy on chest and triceps days!). Again, the rubber mallet came to the rescue.Another design flaw, as other reviewers mentioned, is how the armrests attach to the back of the chair rather than the base. This makes the whole chair feel a bit wobbly when pressing down on the armrests, giving it a slightly flimsy feel. Though I do love the fact that it goes up to save space but also for when I play my guitar and record some music.That said, it’s still a major upgrade from my stiff, posture-wrecking gaming chair--and it was actually the same price as this chair too. With this chair, I do love the neck and head support/ They are fantastic—I sat on it today for 5 hours without feeling tension build up in my shoulders or neck. Despite the minor flaws though, it’s a comfortable and ergonomic choice for long work sessions in my opinion. It's also my first 'mesh' chair, and I've heard great things about mesh chair especially in hot summer days as it allows some heat to escape and such, providing some cooling effect, unlike the faux leather gaming chair I had for the longest time which makes me sweat like crazy every summer.Would I recommend it? Possibly. If you're on the slightly average height (5'9") or shorter, go for it. If you're taller though, maybe look for something else. However, be ready to put in some extra effort during assembly, unless of course, the company sees this review and decides to do a better quality assurance in ensuring each pieces goes in smoothly.

Llevaba tiempo buscando una silla ergonómica para trabajar desde casa y decidí probar esta SIHOO M59AS. Después de usarla varias semanas, puedo decir que ha mejorado bastante mi postura y comodidad durante largas horas de trabajo.🔹 Lo mejor:✅ Diseño ergonómico con buen soporte lumbar: El respaldo doble y el soporte lumbar dinámico realmente se ajustan a la espalda, reduciendo molestias al estar muchas horas sentado.✅ Respaldo y asiento de malla transpirable: No acumula calor, lo que es perfecto para climas cálidos o largas sesiones de trabajo.✅ Reposabrazos 3D ajustables: Se pueden subir, bajar y girar, lo que ayuda a encontrar la posición más cómoda.✅ Buena calidad de materiales: Se siente robusta, los acabados son buenos y el mecanismo de inclinación es suave.✅ Fácil de montar: El ensamblaje no es complicado y las instrucciones son claras.🔸 Lo que podría mejorar:❌ El asiento es firme: No es incómodo, pero si prefieres algo más acolchado, quizás necesites un cojín extra.❌ Los reposabrazos pueden moverse con facilidad: Aunque son ajustables, a veces se sienten un poco sueltos y podrían tener más estabilidad.❌ No tiene reposacabezas: Para algunos puede no ser un problema, pero en una silla ergonómica se echa en falta.📌 Conclusión:Si buscas una silla ergonómica cómoda, transpirable y con buen soporte lumbar, esta es una excelente opción. Tiene ajustes útiles y un diseño de calidad, aunque el asiento es algo firme. Por su precio, ofrece una gran relación calidad-precio.

I originally got this chair to replace my gaming style chair at home but it just wasn't very comfortable for that purpose. I like to tuck my legs in while I play games and do other tasks at home, so I took this chair to work. This is where it really shines.This chair really helps keep straight posture and has a nice adjustable lumbar area. The head rest has a ton of adjustability as do the arm rests. There is even a neat little coat/bag hanger built in to the back. My favorite thing about this chair has to be the mesh. It is so comfortable, and infinitely breathable. It feels very thick and sturdy but still conforms nicely to your body.For the price, this is a great office chair. Highly recommended.

Chaise ergonomique de qualité, que se soit les plastiques ou le "tissu" en maille.Facile à monter à deux. Peut se faire seul mais il faudra jouer un peu l'équilibriste à certains moments.Très confortable et pleins de réglages pour s'adapter au mieux à sa morphologie.Parfait pour des heures de travail dans le confort !
