AndaSeat is known for gaming chairs. There is no doubt about that. While they do have some chairs that are promoted as professional chairs or office/gaming chair hybrids, they look and function much like gaming chairs.
However, as I have shown with the Secretlab Magnus Pro Standing Desk , if the product is of high quality and operates the way you need and want it to, it doesn't matter what the original intention was. If it works for your scenario, it works. The Magnus Pro standing desk is technically a gaming desk; however, I put it through the paces of a professional standing desk and performed wonderfully.
After all, our best office chair on a budget is a similarly gaming inspired desk seat. So, while the AndaSeat Kaiser 4 XL - an extra-large version of the popular Kaiser 4 Series (check out our AndaSeat Kaiser 4 review for more details) - might originally be aimed at gamers, it more than fits into the professional workspace setting. The AndaSeat fills a similar space in my head.
It's a bridge between the gaming and professional space. Yes, it looks gamer, but it functions like many of the mainstream best professional ergonomic office chairs. It's a clean, simple colored chair with high levels of adjustability and excellent ergonomics.
It is comfortable for all-day use, and this one is the XL model, making room for those who are a bit bigger. Bigger can mean many things. For example, my team member who uses this chair the most is 5'11" and is 215lb.
He's a professional fitn.
