RIWI® FAQ – Frequently Asked Questions

Our blocks don't need magnets or Velcro – the secret lies in the material! The special RIWI® foam has high friction, making the blocks feel stable when stacked and preventing them from slipping easily. This allows children to build, dismantle, and rebuild freely – over and over again.

Yes! Our RIWI® mini blocks are the perfect solution if you have limited space or want to start small. They're lighter, more affordable, yet just as creative and durable as the larger ones. With the RIWI® mini carry bag, you can even store them compactly.

Absolutely! The sizes are designed to complement each other: a mini block is half as long and one-third as high as an XXL block – allowing you to build transitions, fill surfaces, or add details. This brings even more play ideas – especially when multiple children play together.

We have two practical solutions:

• 👜 The RIWI® XXL carry bag holds 12 large blocks – ideal for small sets or if you want to stay flexible. Best of all: the filled bag can also be used as a stool or platform.
• 🛋️ The RIWI® Couch Cover is perfect for larger sets – it transforms 24 XXL blocks into a full-fledged play sofa that also serves as a cozy cuddle corner.

Both options are practical, well-thought-out, and fit perfectly into family life.

Velour is soft and cuddly – ideal for playrooms or kindergartens. The blocks are slightly heavier and hold together particularly well.
PU cover is wipeable and smoother – perfect for therapy rooms or places where hygiene is especially important.
Both options are high-quality, durable, and, of course, free from harmful substances.

Yes – absolutely! Safety is our top priority. All RIWI® products are tested according to the current toy standards (EN 71, CE) and approved for children from 36 months. Our foams are free from harmful substances and are regularly tested by certified laboratories – in Europe and the USA.

The XXL blocks are vacuum-packed to save space and be environmentally friendly. The volume is reduced by up to 80% – allowing up to 48 blocks to fit in a single box! Shipping within Switzerland is via DPD, directly from our Swiss warehouse – no customs, no waiting time.

Don't worry – that's completely normal. After opening, the blocks need a short time to return to their original shape. In most cases, this takes less than 20 minutes, but depending on temperature and humidity, it can take up to 72 hours.

Please unpack the goods immediately upon receipt!
With some steam (e.g., from a steam iron), you can gently accelerate the process.

You can easily clean the RIWI® blocks and covers by hand or in the washing machine at 30 °C. Please use a mild, child-friendly detergent and avoid fabric softeners.

💡 A detailed care guide can be found on each product page under the "Care Instructions" tab.

No – and that's intentional! RIWI® is an open construction toy that doesn't limit your child's creativity but enhances it. Whether it's caves, castles, obstacle courses, or slides: your child decides what to create. This makes RIWI® not only exciting but also strengthens independence and confidence in their own imagination.
