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

felt like id bought a premium product as soon as the box opened. well packed even colour coded bubble wrap. all screws and tools present and well marked (if a bit awkward to cut free!). plenty of extra parts included. white gloves to help avoid marking the chain during building. chair feels great and looks the part. have to test it for a few weeks to make sure the lumbar support is OK but so far very satisfied

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.

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

My previous home office chair lasted less than three years as the gas cartridge (?) refused to hold the chair up under my weight (100kg). This time I did some more research and decided to pay a bit more - the last one was £150 and buy a chair rated to 150kg. This one is on sale at £329 but, as a brought a 2nd described as 'used', I only paid £260. Hard to tell how it has been 'used' as it seems brand new.Slightly fiddly to put together in parts - you really need two people when attaching the arms rests to the back attachment. Other than that simple and well described with all the bits (and spares) clearly labelled.The chair itself is heavy and clearly a step up from my previous chair. It's comfortable (so far). If i had one criticism, its that the headrest is a bit low (I'm 6ft).Happy with the purchase.

Review: SIHOO Doro C300 Ergonomic Office Chair with Ultra Soft 3D ArmrestsThis 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.
