How was RIWI® born?

As engineers, construction has always been a part of our lives. Inoue childhood we loved to build caves out of upholstery and hide in them, and to build high towers out of building blocks, only to destroy them again afterwards. 

We had to realize that there is not a single toy for this purpose that is on the one hand so versatile and giant and on the other hand also affordable for private households.

Why We Use Foam for Our RIWI® Blocks

After testing many materials, we found the perfect one for our XXL building blocks: high-quality polyurethane foam – soft, safe, and perfect for kids.

We developed our own custom foam formula!: RIWI® was the first to use PU foam without coating for children’s toys.
Our foam is independently tested to meet strict US toy safety standards (ASTM).

✔️ Certified safe material
✔️Machine-Washable
✔️ Durable and long-lasting fun

Protective Covers for Heavy-Duty Play

Some of our customers – like schools, daycares, and therapy centers – need extra durability. That’s why we created our protective velour covers.

They add just the right weight and grip for better building, even with active use. Plus, the soft velour makes every block feel extra cozy and inviting.
