About us
RIWI buildit stands for high-quality and giant-sized foam building blocks.
Our XXL building blocks delight numerous children every day in educational institutions as well as in private households all over the world.Here we want to give you an insight behind the scenes.

Kids love RIWI®
Since 2017, RIWI® has brought joy to over 50,000 children — and we’re just getting started!
It’s amazing to see how much kids love this creative and empowering gift.
✨ Over 95% of families in our surveys say that RIWI® blocks are their #1 favorite toy and the highlight of every play session.

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.

Smart Storage for XL Blocks
Giant foam blocks are fun — until they take over the living room.
That’s where the RIWI® Couch Cover comes in!
Each cover fits 24 RIWI® XXL building blocks, turning your pile of play into a neat and tidy play couch.
Perfect for easy storage and on-the-go transport.
