There are two main criteria that should be considered:
1. The body height
2. The range of use
1. body height
We offer 3 ball sizes for the following body heights:
BOL 55: approx. 130-155 cms
BOL 65: approx. 155-180 cms
BOL 75: approx. 180-200 cms
Here you can select the ball size that generally fits your body size. Tip: Especially in the border areas between two ball sizes, i.e. approx. 152-157 cms and 178-182 cms, you should rather opt for the smaller size if you want to sit comfortably and cozily, or opt for the larger model if you want to sit sportily.
2. field of application
If you want to use the ball purely for free sitting or training, you can select the size according to the point. However, if you want to use your BOL for working in the office, the place of use is also an important decision criterion. For ball sizes 55 and 75 you should use a height-adjustable desk, otherwise you will not have a comfortable, ergonomic position, you will sit too high or too low. For standard desks with a height of approx. 72-76cm, you should always go for a VLUV 65, even if you are shorter or taller.
