I like the chair, however, having a separate cushion for the lumbar support doesn't really work well. It fell over every time I got up. There should be lumbar support built into the back of the chair. I also had to add an ergonomic seat cushion because the seat was very hard. This solved the issue of the lumbar support falling down when I got up because I tucked it behind the seat cushion to hold it in place, but the lumbar support at that low height resting directly on the chair is way too low for a proper lumbar support. It would be well worth paying more for a chair with the lumbar support in the chair and a much softer seat cushion. I like the way the rest of the chair functions, such as the arm rests and way the sides of the chair wrap around.

I recently bought a Master chair for my desk, after my partner highly recommended it. I’d been using a dinner chair as my desk chair for over a year, which caused me some back pain. The Master chair has been incredible so far! The back support is amazing, and I love how easy it is to adjust the settings to change my posture throughout the day. I’m really hopeful it’ll help undo the damage from my old chair. Overall, I’m so happy with both the product and the fantastic customer service!

I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model.
