## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value
*by  on Reviewed in the United Kingdom 25 August 2026*

Its heavy, and the order of the instructions was wrong. Following the order of assembly of the product video demo would have made my life a lot easier. Having said that, amazing chair. Love it. Glad I bought it.

### ⭐⭐⭐⭐ A decent quality once you've settled in
*by  on Reviewed in the United Kingdom 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

### ⭐⭐⭐⭐⭐ Very comfortable especially in warm weather.
*by  on Reviewed in the United Kingdom 22 August 2026*

Best chair I've ever had, worth every penny. Love the amount of adjustments I can make.
