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

Review: SIHOO Doro C300 Ergonomic Office Chair with Ultra Soft 3D Armrests This chair on offer price is such great value, at full price would easily be worth the price. I was really in so much doubt changing from my comfy slouchy executive chair to this one. I had developed back problems and realise now it was my comfy slouchy chair. Within hours on this new chair I feel supported, sit correctly and the quality is great. It was so easy to assemble with clear instructions, took me just 20 mins. Everything was clearly labelled in a blister pack, wish other would do this also! My surprise was the weight, its so heavy but that is such a positive for me as its of great quality and sturdy. Adjustable in every way, such a great chair.

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.

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.

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 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.

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.

Ich verwende den Stuhl nun ein halbes Jahr. Bisher ist noch nichts vom weißen verfärbt und das Mesh macht immer noch einen stabilen Eindruck. Das „Lendenkissen“ macht sich auch gut, da es sich der Sitzposition einfach anpasst. Also kein nerviges einstellen. Die Kopflehne fühlt sich eher als Nettgemeint an, da sie nach hinten sackt, sobald ich mich wirklich gegenlehne. Insgesamt sind alle Module da doch etwas zu leicht einzustellen und deshalb verstelle ich die (z.B. Armlehnen) häufiger als gewollt. Gewöhnt man sich aber dran. Am Anfang hatte der Stuhl sehr krass geknarrt, das lag aber daran, dass ich eine Schraube nicht fest genug gezogen habe. Danach war der Still. Ich bin sehr zufrieden mit dem Stuhl und würde ihn weiterempfehlen!

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.
