SIHOO Doro C300 Ergonomic Office Chair, Dynamic Lumbar Support, Grey

Its heavy, and the order of the instructions was wrong. Following the order of assembly of the product video demo would have made my life a lot easier. Having said that, amazing chair. Love it. Glad I bought it.

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

I spent almost 4 months looking for a desk chair. I found this one thanks to Claude. It has made a huge difference in my day to day. Specially since I spend 8-10 hours a day on my desk. Great quality. Comfortable.The instructions are a bit confusing but I manage to assemble it myself.

Best chair I've ever had, worth every penny. Love the amount of adjustments I can make.

I have not regretted enough having bought this chair. I wasted a sizable amount of money for the most uncomfortable desk chair I have had in my entire life (and I bought it 9 months, ago, mind you) Is it solid? Yes. Does it serve its purpose? NO. Design is horrendous. The back rest and the lumbar support are what annoyed me the most. I actually ended up with dorsal spinal pain because the chair is CONSTANTLY PUSHING YOU FORWARD. Therefore, you are not resting your back against it, you are constantly fighting the back"rest". The lumbar support is the first one that kicks you out; it's too "vigorous", it might be suitable for someone with hyperlordosis, but not for normal human beings. Furthermore, the seat is equally annoying. The set positions are very fiddly (good luck finding where the position should be set) and the neutral position, is again, like most of this chair, pushing you out of it. I am terribly frustrated. I paid a huge amount of money for this chair under the promise that it is unbeatable. I gave it as many good attempts as I could, but after 10 minutes of sitting here I didn't want to be in front of my desk anymore. What a huge disappointment. In summary, it's £300 down the drain.

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.

Generally an excellent chair with loads of support adjustments. However, the adjustable arm rests are not held very securely once set in the desired positions and tend to slop around quite easily. The instructions for the adjustments are minimalistic to the point of being non-existent. I have also found a small lever hidden around the back of the back support column and I have no idea what it does!

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.

Après + d'un ans d'utilisation, je conseille cette chaise.Je suis totalement en télétravail et j'ai developé des douleur sur mon dos. J'ai acheté cette chaise ergonomique après avoir passé des heures à chercher une solution pour soulager mon dos pendant mes longues journées de travail. Je suis bluffé par son confort et son design !Le dossier épouse parfaitement la courbe de mon dos, et le soutien lombaire est ajustable, ce qui me permet de l'adapter exactement à ma morphologie. Les accoudoirs sont bien rembourrés et réglables, un vrai plus pour éviter la fatigue des bras. Mention spéciale pour l'assise, ferme mais confortable, qui me permet de rester assis sans douleur pendant des heures.Le montage était simple et rapide grâce aux instructions claires, et les matériaux respirent la qualité. C'est un investissement que je ne regrette pas du tout. Je recommande cette chaise à tous ceux qui cherchent à allier confort, style et ergonomie !

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.

La silla es muy comoda, a principio cuesta un poco saber todas las posiciones que tiene pero en un rato ya sabes como va, la unica pega es el precio en amazon, en la web oficial esta mucho mas barata

Perfect and easy to fix
