Quadro™ construction kits reduce the amount of time kids spend watching TV or playing games on their digital devices. Instead, the children will need to think, to analyze, to plan, to design and ultimately to assemble and test their structure. The ultimate objective is not just to look at the “creation” on a tabletop, but to actually play on the structure and enjoy some physical fun. The simplicity, yet sophistication of the Quadro™ construction play system makes it especially valuable for kids with special needs. Quadro™ construction kits are made from very durable plastic components and can be used indoors or outdoors, summer or winter. In fact, the structures can even be used in water. All Quadro™ kits are shipped with design suggestions and assembly plans – just to get you started. There is also a large on-line data base from which to choose additional designs including the parts required. For the ultimate Quadro™ user, there is also a very sophisticated 3D program to design virtually anything. To ensure safety, each kit includes a safety manual that outlines the how to undertake basic assembly as well as safety warnings. Tens of thousands of Quadro™ kits have been sold worldwide since 1979. In many families, the components are being used by the third generation! Every kit and component sold today will match the kits that were sold nearly 40 years ago. Each kit has a different number of parts. The more parts you have, the more you can build.
