Our story


After 3 years of development at the Emil Adolff Plastic Company in Reutlingen, Germany, QUADRO is born. Its inventors, Hubert Georg und Doris Rüther, present it at the 1979 Nuremberg International Toy Fair.

Under the oversight of the German inspection authority, TÜV Deutschland, QUADRO is tested in 16 nursery schools. The results are extremely positive and the system is granted certification.

QUADRO splits from the Emil Adolff Plastic Company – QUADRO should not be a product for a single market but a system for many markets throughout the leisure sector, for children and adults in the home and garden, indoors and outdoors.


With its outstanding design, QUADRO won the Product of the Year Award from the German Trade Association for Plastic Consumer Products.

QUADRO continues to grow in little and big ways: miniQUADRO is developed and distribution spreads worldwide.


Countless inventions increase the product range, such as air-filled tubes for floating in water and a mobile kit adding wheels.

The QUADRO GEAR and QUADRO DRIVE were engineered as well as the QUADRO Garden Furniture and QUADRO Exhibition Displays.



QUADRO gets even more colourful. Construction kits now come as standard with tubes in 4 colours.

Plexiglass panels are introduced to the QUADRO system and it possible for children to build green houses.

At the Paris-Dakar Rally the desert fitness of QUADRO is tested. 😉

The QUADRO children’s furniture program wins the Product of the Year Award for Plastic Goods from 1998. In addition, trailers are developed that act as complete mobile homes.


At the beginning of 2004, a complete reorientation of the company structure is undertaken. The owner-managed QUADRO DER GROSSBAUKASTEN GmbH becomes responsible for the further development, production and worldwide distribution of QUADRO.

Our passion for innovation and new developments is further evidenced by the integrated slide, which can be connected to any QUADRO climbing frame without screws.

QUADRO wins the Practical-Pre-School Award, the Excellent Play Award, and the Toy Award.

QUADRO Evolution Cube Cover


There have been countless new developments since 1979 but not much has changed to the core QUADRO system. That is why QUADRO products made today are fully compatible with those products manufactured all the way back to 1979.

QUADRO is not a trend or an elitist product. QUADRO is simply THE toy that kids should grow up with because it is extremely well designed, very safe and incredibly versatile.
