How did RIWI come about?

As engineers, designs have always been a part of our lives. As kids we loved building caves out of cushions and hiding in them and building tall towers out of blocks and then destroying them again.

We had to realize that there is no single toy for this purpose that is so versatile on the one hand and affordable for private households on the other.

Why foam?

After several prototypes, we finally found the perfect material for our XXL building blocks: polyurethane foam .

As we are the first company to use uncoated PU foam in children's toys, we have developed our own foam formulation to meet the chemical safety of toy regulations on the one hand and to achieve perfect construction properties, durability and longevity on the other. This formula has been developed and improved over the years.

Why velor covers?

Some of our customers are public institutions, day-care centers and schools. The conditions are different and the stakes are tough . That's why protective covers were invented. Velor is just right because you can still build well with the now heavier building blocks (keyword: friction). Another positive effect is that the building blocks with a velor cover are very cuddly .

How can I store the XXL building blocks?

Giant blocks are great until they block the whole living room. That's what the RIWI Couch Covers are for. 24 XXL building blocks can be hidden in a couch cover. So you can use it as a play couch and easily transport it.
