## Description

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

### ⭐⭐⭐⭐⭐ Extremely comfortable seat good lumbar support
*by S***R on 8 January 2026*

the chair is comfortable with good lumbar support. I do enjoy leaning back and avoiding work as the headrest is perfectly placed lol, it was well packaged to make putting it together much easier than it could have been, in fact the way the blister pack for the screws was set out made it much easier to assemble than you think it would be. it is an extremely comfortable seat and because its mesh I'm looking forward to not having the sweaty back my old leather chair gave in the heat.
