Why is dynamic sitting important?

Children today spend a lot of time sitting – but often too still. The Base brings movement back into everyday life – naturally, through small, playful micro-movements while sitting. This strengthens posture, attention, and self-regulation – scientifically sound and practically applicable to everyday life.

Sitting ≠ Being still

Children today spend more than 8 hours a day sitting – often motionless. This rigid posture puts strain on the spine, metabolism, and attention.

More health

The curved base activates 360° micro-movements. Studies show that dynamic sitting reduces pressure on the intervertebral discs and prevents back pain.

More focus

Even a slight rocking motion of just a few centimeters increases concentration and keeps the brain more alert than sitting rigidly.

Self-regulation & fun

Rhythmic movements help to reduce nervousness and organize sensory perception – ideal for school, home office & therapy.

That's why Stapelstein® Dynamic

Because you get more than just a stool – you get a dynamic design ecosystem that grows, protects, and inspires. In short: Stapelstein® stands for sustainable quality, playful innovation and a modular promise: One element, endless possibilities – today, tomorrow, for a lifetime.

Developed in collaboration with families and experts

Educators and ergonomists collaborated on the design of the shape, height, and balance curve. The result: a product that meets real everyday needs – not just a pretty concept.

Modular by design, personal by choice

Click, stack, combine: The Base seamlessly connects to any Stapelstein® Original or Board. A single new element transforms your existing set into a complete children's or family stool. Small step, big impact – no tools required.

Fresh colors & iconic Bauhaus design

Rich colors meet clean lines – instantly recognizable, always eye-catching. This is how the brand theme is embodied. Design + Movement literally visible and makes you want to use the piece of furniture.

Multiple uses instead of single-purpose furniture.

Sitting, playing, balancing, training – and then starting all over again. The Base encourages movement, strengthens posture, sharpens focus, and supports sensory self-regulation. A tool for body and mind.

Made in Germany, produced in a climate-neutral manner
