1. Understand the Ergonomic Concept of Boulies
Boulies is committed to giving you the most comfortable experience when working, and it can also effectively prevent diseases such as sciatica, office chair butt, and tailbone pain.
The core concept of Boulies is to let you have an ergonomic sitting posture naturally. Create an office chair that is not only beautiful but also can support various postures of the body, while reducing physical stress and promoting work efficiency. We know that every investment you make needs to be valued, especially when you spend more and more time sitting.
We have launched two different product lines - EP and OP, which are finely divided according to user needs. Just like jogging, cycling enthusiasts have different requirements for equipment. The needs of working and entertaining at home, and working at a desk for a long time every day, are also different. We are well aware of this difference, so when designing office chairs, we designed two different product series based on ergonomic principles.
