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

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!

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

Super comfortable. Fixed back-pains I used to have with my old chair. Great customer service too.

Having previously bought two run-of-the-mill gaming chairs, both of which didn’t last long, I think this ergonomic office chair is a significant leap forward in the right direction. The amount of adjustability is refreshing and extremely useful for achieving the right fit. One of the aspects that surprised me the most is the mesh material, it is sturdy, stretchy, firm and extremely comfortable. On top of this, the breathability of the material is very noticeable, more than what I thought it would be; it's fantastic now in the Winter and it will be even more so in the Summer. The assembly was easy with the tools and fixings provided, I didn't encounter any issues and all of the parts fit together nicely straight out of the box they were securely and safely packed in. Overall, I can say that I'm very happy with this chair.

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.

Update Again: got replacement chair from initial and after not even half a year the arm has gone wobbly on one side, do not buy from this brand Note: customer service was good they offered a full refund added a star for that, originally 2. The overall shape with lumbar support does make it comfy to sit on I wont lie. Although after a week it’s creaking and making noises like it’s being used for over a year. The feet and legs are cheap and low quality and it is no way near a £300 chair. Im a below average size male and would not reccomend for anyone taller than 5 foot 9 as it is quite small but good size for someone smaller like me. If I was to reccomend anything spend an extra 1-200 to get a refurb herman miller if you want a real good quality that will truly last.

Bought this chair in the prime day sale, it's of good quality with a fabric mesh so it doesn't get uncomfortably hot in the current heat wave we're having in the UK. The chair operates on a simple click adjustment mechanism where you need to fully set it to the maximum position to effectively reset it and then click to your preferred height, depth and tilt. Putting it together took about 30 minutes. It comes more 'flat packed' then other chairs I've had on the past (Secret Lab, Noble Chairs). My only downer for me is that my cats are already thinking it's a new scratch toy. If you have cats consider they may like the fabric too much. I'm having to use a cover when I'm not around to make sure they don't destroy it.

I bought the SIHOO Doro C300 Ergonomic Office Chair in late November 2023. It came very well packaged and was easy to assemble. Once in use I found it very comfortable and I was impressed with the solidity of the chair. Unfortunately, in February I found the left arm had failed at the joint of the arm rest and contacted Sihoo to see what they could do. I received a prompt response requesting further information about the failure, which I answered with a short video to show the problem. They immediately came back with a promise to replace the whole arm, which I received a few days later. Replacement was easy, requiring 2 bolts to be unscrewed and re-fixed. During this period I also queried an issue I had when I first got the chair - the chair lift movement was a little restricted and did not work well with my rise and fall desk. I had to maintain the desk at its lowest level and the chair at its highest. The answer was a suggestion to find a replacement gas lift that met my requirements and that they would put £25 towards the replacement. After careful measurement I found a replacement gas lift for £21 and ordered it. I had a refund of this almost by return. When I came to fit the new gas lift I found the original was fully stuck in the chair feet 'spider'. I tried using a pipe wrench and a sledge hammer but could not remove it. Sihoo sent me a replacement 'spider' and I refitted the chair feet and the new gas lift - took me under an hour to complete. Now the chair is working fine and I have movement on both the chair and the desk to be able to find a comfortable position. During this experience Sihoo answered all my emails promptly and gave every assistance. The whole issue was cleared within half a month, including the deliveries. I have been very pleased with the response I received from SihooOffice.

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.
