The complaints
When sitting becomes a problem:
Over 30% of people with sedentary jobs develop health problems during their lives. These can be very diverse.
Most people know at least one of these symptoms. Often so familiar that they are hardly noticed anymore. A pull when standing up, a stiff hip after sitting, tense shoulders in the evening. These are small signals that are quickly overlooked in everyday life because they creep in unnoticed and never seem bad enough to be taken seriously.
Common complications and their possible causes:
- Tension in the neck and shoulders = Cervical Spine Syndrome
- Difficulty concentrating = reduced oxygen and nutrient supply
- Dull, pulling pain in the lower back = Lumbar Spine Syndrome
- Stiffness in the hips = shortened hip flexors
- Problems standing up = atrophied gluteal muscles
- Tired legs = impaired lymphatic flow

The Reason
How your symptoms can arise:
In the office or in your free time. Most problems do not arise from "wear and tear", but from:
- Poor posture
- Sitting inactive for too long
- Lack of daily movement
- Inactive or underworked muscles
Your body is not broken – it just needs the right impulses.
Back pain, tense shoulders, trouble concentrating, a stiff hip, or tired legs.
Sitting for long periods can quietly cause uncomfortable aches and pains
The reason: A lack of movement. A hard, rigid office chair holds your body in an unnatural, fixed position for hours on end. This causes your neck and shoulders to tense up, your concentration can drop, and a dull, pulling pain can develop in your lower back. Your hips and legs also stay almost completely still, which can lead to stiffness, heavy, tired legs, and difficulty getting up. A hard, non-dynamic seat surface keeps your hip joints from moving enough to stay mobile.
These symptoms are signals from your body that it's missing movement.
We bring movement to the way you sit.

The Solution
BOL - The ergonomic sitting ball
Gentle movement impulses stimulate your circulation and support the production of joint fluid.
BOL – The ergonomic sitting ball brings back exactly the movement impulses you're missing. Instead of sitting rigidly on an office chair, you stay gently in motion even on long working days at your desk. Completely automatic, with no extra effort.
The fine movement impulses help your body compensate for one-sided sitting and can reduce typical discomfort as a result.
Here's how BOL supports you:
- Small micro-movements stimulate natural compensating movements and relieve the hip area.
- The active sitting position encourages an upright posture and strengthens your back muscles.
- Gentle bouncing improves the nutrient supply to the discs and can boost concentration
- The soft, air-filled seat surface activates your glute muscles and provides excellent sitting comfort.
- The unstable seating engages your legs, helping to keep your body balanced.
