Stapelstein® Base – Modular children's stool & balance base for dynamic sitting
The Stapelstein® Base is the powerful foundation of our Dynamic Sitting System. Its curved underside inspires gentle 360° micro-movements, activates core muscles, and promotes a natural body feeling – all without screws or technology. Made from ultra-light, 100% recyclable EPP, it combines minimalist Bauhaus design with maximum load capacity up to 120 kg. Whether solo as a children's stool, combined with Board or Originals: Base grows stackable with every stage of life, fits into any interior, and makes movement an intuitive part of everyday life.
Why is dynamic sitting important?
Children spend today > 8 hours daily sitting – often motionless. Rigidly staying in one position strains the spine, metabolism & attention.
The curved Base activates 360° micro-movements. Studies show: Dynamic sitting reduces intervertebral disc pressure & prevents back pain.
Just a few centimeters of rocking increase concentration and keep the brain more alert than rigid sitting.
Rhythmic movements help reduce nervousness and organize sensory perception – ideal for school, home office & therapy.
