I was looking for a desk chair to use when I work at my parents' house, and I chose this product after seeing it in a store. By the way, I didn't add the optional armrests. I was looking for a chair that would match my desk, which is small and low to the ground (H600mm), and this product was pretty close to what I wanted. If I could have been a bit more picky, I would have preferred it to be a little lower (the lowest seat height is 400mm), but I felt that the hardness of the seat and the shape of the backrest made it difficult to get tired unless you were sitting for a very long time. What I hadn't expected was that it was very easy to use when playing the guitar. If you raise the seat high and put your right foot on the caster leg (? part, and you can rest your right foot on it. It's so easy to use that you'll wonder if you bought it for that purpose (lol). It doesn't have any fancy gimmicks, but with its simple design and functionality, I think it's a good product that more than satisfies you when you look at the price.
