SIHOO Doro C300 Ergonomic Office Chair with Ultra Soft 3D Armrests, Dynamic Lumbar Support for Home Office Chair, Adjustable Backrest Desk Chair (White)

I've needed a better office chair since working from home during lockdown showed me how inadequate my last chair was. To be honest you can pay eye watering prices for a decent chair with good back support so I really had to do some digging to get a good deal. This chair ticks all the boxes. It's comfortable, supports my lower back and is easy to adjust. It is a well made, solid piece of furniture so it does take a bit of effort to put together but the instructions are clear, all the necessary screws are provided as are the tools. Really please with this purchase!

When my last lock down office chair fell apart I settled on this one to replace it. Its a good solid item and fairly heavy so like others advise to assemble in the room it will be used in if possible. There are some YouTube review videos that also show assembly but the instructions in the pack are fine. They also provide extra nuts and bolts so dont worry if you have a few spare at the end. I opted for a mesh chair this time as my last faux leather one was less comfortable in hot weather. This mesh gives very good support and more than might be anticipated from the images. The back rest does take a bit of getting used to, but after a little time using the chair I really like how it adjusts to the small of your back. The gas lift has the usual up and down but you can also lock the chair in a fixed position or in a recline mode where leaning back allows you to gently recline backwards. The seat back adjusts up and down with a good range of settings. The arms adjust up and down but the sideways adjustment is quite loose so the arms do move around, not when sitting but if you knock them. This doesnt bother me as i like being able to adjust the direction of the arm rests to different angles. There is also a neck rest, which looked a bit gimmicky to me but actually gives good support if needed. We have Herman miller chairs at work, and i find this one as comfortable as those but at a much more reasonable price.

This chair is well-designed and feels very sturdy, and feels really good quality. Assembly was a breeze — all the nuts and bolts arrived clearly labelled, and the instructions were straightforward and easy to follow. It took very little time to get everything set up. Materials used feel premium and castors glide smoothly across the floor. It’s also highly adjustable, with mechanisms that make it easy to tailor the chair to suit the individual. The simplicity of the adjustment systems means multiple users can switch in and out with minimal hassle. Reclining is a particular strong point. When leaning back, the chair offers noticeably better lumbar support, and the headrest shifts into a more comfortable position. It’s supportive and stable, even for heavier users (around 130kg), and feels dependable even when fully reclined. The lumbar support is surprisingly good. Although I usually prefer a locked setting over a spring-loaded one, this design works well and offers a decent level of support once you’ve got used to it and means when you recline you don't need to also adjust the lumbar support because it just adjusts with you. At 5'10", I first thought the headrest sat a little low for me. But after a couple of weeks now I think i've adjusted to the chair, along with my posture (for the better) so now seems much better. The armrests are really easy to move around and means when im slouching or leaning its really easy to adjust them to a comfy position. Overall, this is a high-quality chair with thoughtful features and excellent ease of use. It’s probably best suited to users multi-user settings and worth noting that the premium materials do mean its quite heavy

This is a modern mesh office chair. I find it a little harder than my old office chair but the mesh is actually very comfortable and the lumbar support works well. This chair is quite big and heavy and could support larger people. I'm 5'7" and small/meduim build and it's ok for me but would easily suit much larger people. The lumbar support mechanism is a bit unusual in the way it moves when you recline but I found that for me it works well and much better that my old chair which had a fixed lumbar support. The wheels is comed with don't work well on thick carpet but the manufacturer was kind enough to provide replacement rubber wheels on request and for free which work well. It's solidly built and should last for many years I think. The only things they could so better would be to allow the arms so be fixed rather than constantly rotating and allow the chair to recline a bit more.

I bought this chair for my girlfriend, who is 160 cm and 45 kg, and she absolutely loves it. She has occasional back issues, and the dynamic lumbar support on the Doro C300 has made a real difference — it isn’t just a decorative feature; it genuinely provides proper support and encourages a healthy posture. I’ve also used the chair occasionally over the past year, and I have to say the build quality is excellent. The mesh is high-quality — not too firm and not too soft — and remains very comfortable even during long sitting sessions. The chair feels well constructed overall, with materials that suggest it will last for years. It’s also worth noting that the chair is not noisy or squeaky, which is a big plus. However, this chair won’t be ideal for everyone. If you’re a taller or larger person, it may not be the best match. I’m 186 cm and 80 kg, and while the chair is comfortable, the seat base feels a bit small for my build. That is the main reason I didn’t purchase one for myself. Another minor drawback is that the armrests do not lock, which can be slightly annoying as they shift more easily than I’d prefer. Overall, if you are small to medium-sized and want a chair with excellent back support, the SIHOO Doro C300 is one of the best ergonomic options in its price range. It offers genuine lumbar support, great comfort, and high-quality materials — especially suitable for anyone needing extra lower-back stability.

I just built it. It’s looking great!

Perfect and easy to fix

Od ponad roku używam krzesła SIHOO Doro C300. Krzesło zostało zaprojektowane z myślą o komforcie i jest bardzo wygodne. Siedzisko i oparcie z siatki są oddychające i zapewniają chłód podczas cieplejszych dni. Materiał oparcia lędźwiowego naciągnął się po pewnym czasie. Zgłosiłem to do obsługi klienta i szybko dostałem nową część na wymianę. Ogólnie jestem zadowolony z tego produktu oraz obsługi klienta.

Günün 8 saatten fazlasını çalışma koltuğunda geçiriyorum, dolayısı ile ergonomik, kullanışlı ve kaliteli malzemelerden oluşturulmuş bir koltuk ihtiyaç olmaktan çıkıp zorunluluk durumunda oluyor. Ben satın almadan önce iç ve diş pazarda mevcut koltukları zaman kısıtı olmadan 1 yıl kadar araştırdım. Ve maalesef ülkede bu kalite de bir koltuk üretimi yok, yurt dışında 300-400 dolar olan bu koltukların ithalatçıları ise 3 katına satıyorlar, tabi yine bu kalite garanti değil. Hem SIHOO' ya hem de Amazon'a teşekkür ederim.

Dopo più di 2 anni di utilizzo costante, a differenza di molte recensioni frettolose, posso confermare che sia una delle sedie ergonomiche più comode mai provate. Sebbene il prezzo sia decisamente lievitato rispetto a quanto la pagai allora, li vale tutti. Il rivestimento interamente in mesh garantisce ottima traspirabilità in estate senza risultare gelida in inverno come succede con quelle in pelle/tessuto. Tra le poche se non l'unica con i braccioli che seguono l'inclinazione. Vanta un supporto lombare solido e preciso dove dovrebbe essere. Il supporto cervicale seppur migliorabile, è sufficiente se ben regolato. Ottima la qualità dei materiali, pistone e base in lega (non plastica). Schienale regolabile perfino in altezza su tre livelli, perfetto per la mia statura (1.85m). Unici aspetti "negativi" rilevati sono la tendenza ad accumulare polvere dietro il supporto lombare se non pulita spesso e qualche lieve cigolio durante l'inclinazione o lo spostamento. Decisamente un upgrade da considerare se lavorate spesso seduti, evitate per favore di buttare soldi sulle sedie "da gaming", sono pura estetica zero funzionalità e vi costringono schiena e spalle in avanti peggiorando drasticamente la vostra postura magari già povera. La vostra schiena vi ringrazierà.
