## 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: Great chair at a reasonable price - 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!
Review: very comfortable chair for the price - 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.

### ⭐⭐⭐⭐⭐ Great chair at a reasonable price
*by M***O on 5 January 2024*

### ⭐⭐⭐⭐⭐ very comfortable chair for the price

### ⭐⭐⭐⭐ A decent quality once you've settled in
*by M***M on 26 April 2025*

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
