Care instructions
Care instructions
🧼 RIWI® foam building blocks are super easy to keep clean:
• Washable in the washing machine or by hand at 86°F
• Use a mild detergent – no fabric softener
• Gently squeeze out wet foam and let it air-dry lying flat – ideally on a drying rack with good airflow
That way, the blocks stay hygienic – even after wild playtime!
☀️ Sunlight advice: Since we deliberately avoid harmful substances, RIWI® foam can be sensitive to UV rays.
Feel free to use the blocks outdoors – but store them in the shade or protected after playtime.
Long exposure to direct sunlight may cause visible changes like yellowing – totally harmless, but noticeable.

Over 85,000 parents trust RIWI®
Since 2017, more than 2 million building blocks have been sparking joy in children every single day. Over 95% of surveyed families say RIWI is their kids’ favorite toy and a true highlight during every visit. Creativity and joy that spread.
We got the RIWI XXL set, and honestly – it was one of the best purchases we’ve ever made! Our kids (3 and 6 years old) play with it every single day. They build castles, towers, tunnels, cars, and even “houses” that go from one room to the next :)
The quality is incredible – super sturdy, yet soft and completely safe when something falls over.
We’ve actually ordered a second set because both kids love building at the same time and their imagination just keeps growing.
You can really tell these blocks are well made – not like cheap foam. They keep their shape, stack perfectly, and the bright colors make the whole room look cheerful.
In short: a toy that truly makes kids (and parents!) happy. <3
Highly recommended!
Great creative and large building blocks! We used it over 5 years now. Still good enough to play with and the kids love it! Even our 13 year old play with them some times. Some small parts get ripped off after hard play.
We use these XXL foam blocks (2x Set of 48) every day in our play area, and the children love them! The blocks are quite big, soft and light, but also durable – perfect for a safe play and building towers, obstacle courses, or cozy corners. I would say, the quality withstands DAILY use - although we have to keep an eye on the kids not pulling small parts out of the foam. . . We highly recommend this awesome foam blocks to all preschools, play cafés, and therapy centers. - BUT also for those wo have enough space at home - they would be a perfect fit for home playgrounds. from my point of view they come with a price - but are totally worth the money.
Worth the money, durable and endless possibilities. Our 6 year old twins received these last year for their birthday. It's been a year and they still love them and continue to use them nearly every day. Highly recommend!
My kids, ages 6-12, have been enjoying these. Fun, easy creativity for all of them. However, I would not buy these again without the covers, and the covers are pretty cost prohibitive. Without the covers, hair and fuzzy and dust easily cling on to the blocks making them look and feel dirty right away. Also, without the covers, the foam seems pretty susceptible to damage; kids fingernails to the corner of a table or piece of furniture. Finally, they require a lot of storage space and easily make a space feel very cluttered. All in all, I love the concept and we are in enjoying them. There a just a few drawbacks.
There isn’t a phone number to call for issues but they respond very quickly via emails!
Thank you so much I can’t wait to give them for Xmas
