Monboxy

“We created Monboxy for our kids.”

Family-owned business producing Montessori-inspired activity mattress sets for kids. The best products are born from a personal necessity. This truly is the case for Monboxy. The family of five – Mārtiņš, Gunita, and our three young kids under six – had trouble finding activities that helped kids learn and have fun. They decided to invest in kids’ independence and development by creating a product that can grow with them and provide not only fun and playfulness but also help them learn gross motor skills and the benefits of open-ended play.

Monboxy family wants kids all over the world to feel secure while exploring and discovering new things at their own pace with Monboxy. They’re raising a generation of young minds that don’t feel boxed in and can solve any problems through exploration. Smart toys play a big role in creating an environment where children feel safe and can develop on their own terms. As a Montessori-inspired family, Monboxy founders believe in hands-on learning and exploration for the kids. This belief drives our mission with Monboxy. The mattress set is designed to support children in developing essential life skills.
