## Description

SIHOO Doro C300 Ergonomic Office Chair with Ultra Soft 3D Armrests, Dynamic Lumbar Support for Home Office Chair, Adjustable Backrest Desk Chair (White) : desertcart.co.uk: Home & Kitchen

Review: Beautiful chair - First off, the product arrived beautifully packaged, complete with all the tools and instructions needed to put it together. It took me about half an hour to an hour to assemble, and the instructions were super easy to follow. Now that I’ve been using this chair for a few days, I’ve noticed that I can sit for long periods of time gaming without any lower back pain, all thanks to the lumbar support. The headrest and tilt tension are a lifesaver, allowing me to sit back and relax. Overall, this chair feels premium and well-built. Plus, it comes with a three-year warranty, which is great for peace of mind.
Review: A decent quality once you've settled in - 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

### ⭐⭐⭐⭐⭐ Comfortable and supportive
*by P***A on 29 July 2025*

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.
