SIHOO Doro S300 Ergonomic Office Chair, Full-Body Coordinated Support

I have to say I was sceptical about buying this chair, I have had Aeron Millers previously so this chair had a lot to live up to. I work from home and spend all day sat at my desk so having a comfortable chair with decent support is really important and worth paying a premium for. The chair does require assemble but the seat and the back with all the mechanism are together as complete units so it was simply a case of bolting the base together, dropping the seat on and then clicking the back into place. I'm not practical at all but it came with good instructions and all the tools so job done in 20 minutes. The build quality is good, all the main support frames in cast aluminium. The mesh material is really high quality, soft to the touch and breathable. This chair is 'very heavy!'...feels quality. When I first used the chair it was 'OK'.....comfortable but not quite as good as expected, "however" I realised the points of articulation on the chair are mind blowing so I set about making adjustments to fit me. The seat slid forwards giving more depth. the back raised up and the lumbar support adjusted forwards. Even the arms adjusted in every way imaginable. The bottom line is that after taking the time to set the chair up properly to my proportions it felt great, very comfortable and very supportive. Love it! All in all, a good purchase and I'm very happy with my choice.

Extremely good company and great chair !! . After trying out many chairs I finally found this one and I’m fully satisfied with it . Sihoo chairs come with 3 year warranty and customer service is great they are ready to help at any time . I had this chair for a couple of months and one of the wheel unfortunately broke but after contacting Sihoo I got a replacement wheel within 2 days and their customer service is great they definitely will uphold their warranty and provide you with a good experience .

Chair seems like it could be good. However, box was clearly brand new As you can see in the video the armrest will not stay up nor will the adjustable back support. The mesh is comfy but some type of plastic rather than fabric. But yet the chair does currently feel supportive on my back and I’ve been having very bad back pain until now. Will contact vendor to sort issues out and update at a later date.

Excellent chair giving great back support. Easy to put together

I recently purchased the Sihoo S300 chair from Amazon, and I couldn't be happier with my decision! From the moment I started assembling it, I could tell it was a high-quality product. The instructions were clear, and all the parts fit together perfectly. Once set up, the chair exceeded my expectations in terms of comfort and support. The adjustable lumbar support and headrest make long hours of sitting incredibly comfortable, especially during work-from-home days. I love how I can customize the tilt, height, and recline to fit my exact preferences. The mesh back is breathable and keeps me cool even during extended use. In terms of design, the Sihoo S300 is sleek and modern, fitting well in my home office. It feels sturdy and durable, even after weeks of daily use. For anyone looking for an ergonomic chair that offers great value for the price, this one is a fantastic choice! Highly recommended!

After purhasing a product we tend to forget the importance of customer servervice unless there is a need. I have been incntact with SIHOO and I have to say I have been pleased with the customer servece. The 5 star rating is purly for this reason. You are not going to find reviews about customer service in Youtube about SIHOO, so I thought I should include it with my review. Pleasent converstion via email, its not instant as this is aftrall email converstion I have to say im very satisfied with the outcome. Hope this helps.

I had high hopes for the SIHOO Doro S300, especially given its sleek and modern design. Aesthetically, the chair is definitely a standout—it looks professional and well-crafted, fitting nicely into a home office or corporate setting. However, functionally, it hasn’t quite lived up to expectations. One of the biggest issues I’ve encountered is the back tilt resistance. It’s surprisingly weak—even when adjusted, it feels like the chair tips back far too easily. For an ergonomic chair at this price point, I expected a more secure and supportive tilt mechanism. The setup process also left something to be desired. The "out-of-box" assembly wasn’t as straightforward as advertised. I’d strongly recommend having at least two people on hand during setup to avoid frustration or missteps. Overall, while the chair scores points on looks, it misses the mark on key functionality and ease of setup. With a stronger tilt resistance and more intuitive assembly instructions, it could be a much better product.

At first the chair was good but I started to realise a few annoying things like when I rest on the air rest they keep tilting up and to stop that from happening you need to push them forward them they stop tilting up. The best rest would keep sliding down. The back rest only has 3 options so it doesny tilt back like normal chairs where you can angle the chair to feel comfortable, so you right then slightly back and then fully back. So only 3 allowed options.Then one day I had the back tilting right back so I could rest and take a nap but I had a clucking nose and bang my chair collapses. So now when I try to tilting back the furthest option 3 I have to get up switch to 3 sit back the chair will have to drop to the bottom and then tilt it back and when you get up allow it to snap back into position then move the switch to option 1. So within a yr it broke. The customer service was so poor so instead of replacing it under warranty I had to film the issue send it to them for the company to send me a part which was the whole main mechanism and expected me to know how to take it apart with all the hydrollics attached. Not that they didn't send me the whole part. The main hydrollics pole was missing and I only realised that when I took the whole chair apart. For a chair costing almost £800 i expected more better quality and if it broke i expected a full exchange rather than them sending a parts and missing parts. Poor quality the chair is not worth the money especially the customer service you get afterwards. There better chairs that are similar and better quality and much better vaule

Tutti i pregi indicati nella descrizione li ho riscontrati uno ad uno....

I recently spent $700 on this chair, and I have to say, it has been a great investment. The comfort level is impressive, and it offers excellent lumbar support, which has really helped with my back pain during long work sessions. The chair feels solid and well-made, with high-quality materials. It’s also quite adjustable, which is nice because I can set it up exactly how I like it. The assembly was pretty straightforward and didn’t take too long. Overall, I’m really happy with this chair. It’s a bit pricey, but the comfort and support make it worth it. If you’re looking for a chair that will keep you comfortable for hours, I’d definitely recommend giving this one a try.

Esta silla es la copia de una que podéis encontrar en El Corte Inglés por el precio de 595 euros. Llevo usándola durante varias semanas para estudiar muchas horas seguidas, y la diferencia con una silla normal es enorme. Lo que más se nota es el soporte lumbar doble, que se adapta bastante bien a la espalda y ayuda a mantener una postura más correcta sin esfuerzo. La silla es totalmente ajustable (altura, respaldo, reposabrazos, inclinación…), lo que permite adaptarla a tu cuerpo y a la forma en la que trabajas. Además, el material de malla es muy transpirable, algo que se agradece muchísimo si pasas mucho tiempo sentado o en épocas de calor. También me ha gustado que, a pesar de ser ergonómica, tiene un diseño moderno y no es aparatosa, por lo que queda bien tanto en una oficina como en casa. El montaje fue muy sencillo y en pocos minutos la tenía lista para usar.

La sedia è ben fatta e i materiali sembrano di buona qualità per il prezzo a cui è venduta. Viene consegnata quasi completamente da assemblare ma le istruzioni sono chiare e permettono un assemblaggio in meno di mezz'ora. Una volta assemblata la seduta è comoda e tutti i movimenti sono fluidi. Io sono alto 183cm e peso 85kg, lo schienale è alto a sufficienza e la rete sia posteriore sia inferiore è solida. Purtroppo dopo 2 giorni di utilizzo ho deciso che non fa per me per 2 motivi: 1. Le piastre lombari in rete hanno la cornice in plastica dura e, standoci appoggiato per circa un'ora, iniziavo a sentire fastidio nelle zone in cui la schiena toccava queste parti dure. 2. La seduta inferiore in rete permette un buon passaggio d'aria, ma anche questa volta la cornice in plastica a cui è fissata la rete genera problemi. Non mi permette di allargare le gambe perché fa da "culla" e limita il movimento laterale non lasciandomi allargare le gambe. Inoltre, appoggiandomi sulla parte dura dopo un po' crea fastidio. Mi dispiace molto non sia adatta per il mio fisico, perché comunque è una sedia ben fatta sia in termini di materiali sia costruttivamente parlando, difficile da trovare a questo prezzo. Ora la sta usando felicemente mio fratello.

It promotes proper posture and alleviates lower back strain. I appreciate how it adapts to my spine's natural curve. - 3D Armrests: The armrests are adjustable in three dimensions: height, width, and angle. This flexibility allows me to find the ideal position for my arms, reducing shoulder tension. - Breathable Mesh Back: The mesh backrest keeps me cool during long work sessions. It's both supportive and breathable, preventing that uncomfortable sweaty feeling. - Tilt Mechanism: The chair's tilt function lets me recline slightly, promoting blood circulation and relaxation. It's perfect for those moments when I need a brief break. - Height Adjustment: The gas lift allows easy height adjustment, ensuring my feet rest flat on the floor. No more dangling legs! Build Quality The S300 feels robust and well-constructed: - Sturdy Base: The five-star base provides stability, even when I lean back. The smooth-rolling casters glide effortlessly across my office floor. - Durable Materials: From the mesh fabric to the metal frame, everything feels high-quality. I appreciate that Sihoo didn't compromise on materials. Aesthetics The chair's sleek design seamlessly blends into any office environment. The black mesh and chrome accents exude professionalism without being overly flashy. Assembly Putting the S300 together was straightforward. The instructions were clear, and all necessary tools were included. Within 20 minutes, I had a fully functional chair. Customer Service Sihoo's customer support deserves a shout-out. When I had a minor issue with the armrest adjustment, they promptly sent replacement parts. Their responsiveness impressed me.
