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: Strikes the sweet spot! Tailored for extended comfort during intensive study sessions - Absolutely thrilled with my purchase of this desk chair as a Christmas gift for my partner. The ergonomic support it offers is nothing short of exceptional, providing a comfortable and conducive environment for those lengthy study sessions. The chair's design strikes a perfect balance between style and functionality, making it a standout addition to any workspace. What sets this chair apart is its sturdy build, ensuring long-lasting durability. The robust construction not only contributes to the chair's overall stability but also gives it a quality feel that instills confidence in its longevity. It's not just a piece of furniture; it's an investment in a comfortable and productive study or work experience. For anyone looking to enhance their study setup, this desk chair ticks all the boxes. As an upgrade, it's a winner – practical, thoughtful, and bound to bring joy to anyone spending hours at their desk. I highly recommend this chair for its superior ergonomic features, sturdy construction, and overall design that makes it a fantastic addition to any workspace.

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

### ⭐⭐⭐⭐ 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
