The Happy Cube puzzles are made of soft, but solid foam of a very good quality, with no smell: EVA-foam (ethylene vinyl acetate). You can wash the foam Happy Cube puzzles at maximum 30°C, so you can play with them for life. Our foam is partly made from natural rubber. The puzzle is produced without CFC’s (chlorofluorocarbon) and is friendly to the environment. 

Karine Doorsselaer, lecturer at Artesis University College of Antwerp (Belgium), told us the following:

"EVA is one of the least harmful synthetic materials. With optimal combustion, only CO2 and H2O are released, so thermal recycling can be done. The calorific value of EVA is similar to that of oil. So you can say that EVA is a rather environmentally friendly plastic.

However manufacturers (mostly from Asia) profit from cheap but harmful substances, such as formamide, by mingling it through their foam. In itself, this process is totally pointless for the production of EVA and redundant."

We feel the health of people is the most precious on earth. We take care for our manufacturers responsability as market builder. We guarantee our foam is 100% European made and child safe, so that Happy Cube puzzling can be really fun, for children and adults.
