RIWI® FAQ – Frequently Asked Questions

Very safe – and that's especially important to us. Our blocks are made of a special foam developed specifically for children's toys. They’re tested according to European EN71, US ASTM F963, and OEKO-TEX Standard 100 – all certified by independent body TÜV Austria. Plus, all blocks are made in the EU – for certified quality you can trust.

Cleaning is super easy – either in the washing machine or by hand. Just avoid using fabric softener and choose a child-friendly detergent. That way, the blocks stay beautiful and safe for longer.

RIWI®️ is more than just a toy. It grows with your child and encourages motor skills, creativity and independence. The soft special foam is safer and quieter than wood or plastic – and makes RIWI the perfect alternative to screen time.

RIWI®️ blocks are made of high-friction foam, so they grip each other when stacked and don’t easily slip apart – making building more stable and fun.

We use a special machine to compress the blocks and save space during shipping. After unpacking, they expand back to their full size on their own.

Our RIWI Couch Covers turn 24 blocks into a comfy play couch with built-in storage. For smaller sets, we recommend the RIWI XXL Bag. Smart and space-saving!
