SIHOO Doro C301 Ergonomic Office Chair, Dynamic Lumbar Support, Grey

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.

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.

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 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.

I just built it. It’s looking great!

Ho acquistato questa sedia da ufficio dopo un'attenta ricerca, e posso dire di essere rimasto molto soddisfatto della scelta. Fin dai primi utilizzi si percepisce l'ottima qualità costruttiva e l’attenzione ai dettagli con cui è stata realizzata. Il design ergonomico è sicuramente uno dei suoi punti di forza: lo schienale in rete traspirante permette di lavorare anche per molte ore senza avvertire quella fastidiosa sensazione di caldo e sudore sulla schiena, mantenendola sempre ben ventilata. Il supporto lombare regolabile svolge un lavoro eccellente nel sostenere la colonna vertebrale nella posizione corretta, aiutando a prevenire dolori e tensioni muscolari, soprattutto per chi come me passa diverse ore al giorno davanti al computer. Molto comodo anche il poggiatesta, anch'esso regolabile, che consente di appoggiare bene la testa durante le pause o i momenti di relax, evitando fastidi al collo. I braccioli sono anch’essi regolabili in altezza e inclinazione, e possono essere facilmente adattati alla propria postura e alla posizione della scrivania, migliorando ulteriormente il comfort durante la giornata lavorativa. Il meccanismo di inclinazione permette di scegliere la posizione più adatta sia durante il lavoro che nei momenti di pausa: si può lavorare mantenendo una postura dritta e corretta, oppure inclinarsi leggermente indietro per rilassarsi, mantenendo comunque un ottimo supporto. Il montaggio della sedia è stato semplice e intuitivo: le istruzioni sono ben fatte e tutto l’occorrente per il montaggio era incluso nella confezione. In meno di mezz’ora la sedia era già pronta all’uso. In generale, le regolazioni sono numerose e consentono di personalizzare la seduta in base alle proprie esigenze fisiche e lavorative. La sensazione complessiva che restituisce è di solidità, comfort e buona qualità dei materiali. Attualmente sto ancora testando la sedia e mi riservo di aggiornare questa recensione nel tempo per valutare la durata dei materiali e la qualità nel lungo periodo, ma al momento la mia impressione è assolutamente positiva. Consiglio vivamente l'acquisto a chi cerca una sedia ergonomica, comoda, ben regolabile e realizzata con materiali di qualità.

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.
