Large group magnetic building blocks turn free play into something everyone can join at once, and that is exactly what the JollyHeap Fun Set is built for. With 300 soft foam pieces designed to connect and hold their shape, up to eight children can build side by side across a play space of roughly 20 square metres, whether that is a classroom floor, a nursery playroom, or a therapy space set up for group sessions.

The set includes four distinct block shapes working together rather than one repeated piece, which is what gives builders enough variety to move from simple towers into figures, hideouts, and furniture-scale structures. Every piece connects magnetically to its opposite pole, shown by embroidered markings on each block, so builders of any age can figure out the system by feel rather than needing to read instructions.

Piece Variety and Building Range

• 228 Cubes - The core building block of the set, giving every child enough matching pieces to start their own section of a shared structure without running short
• 24 Truncated Cubes - Adds angled surfaces to otherwise square structures, letting builders shape rooftops, ramps, and rounded edges into group builds
• 36 Triangles - Brings peaks and angled walls into reach, useful for anything from a tent shape to a boat hull
• 12 Pyramids - Finishes off builds with defined points, ideal for turning a basic structure into a recognizable figure, from a boat to a towering Godzilla-style build

Skills Children Develop Through Group Building

• Teamwork and Communication - Building a single large structure with several other children at once means constantly negotiating who places what and where, developing collaborative and social communication skills alongside the build itself
• Balance, Stability and Weight Distribution - Testing how tall or wide a shared structure can go before it needs support introduces early physics concepts through direct trial and feedback
• Symmetry and Geometry - Mixing cubes, triangles, pyramids and truncated cubes into one structure naturally introduces shape relationships and spatial reasoning
• Creative and Imaginative Thinking - With no instructions provided, open-ended group building supports imaginative problem solving as children decide together what to build next

Because the blocks are soft foam rather than rigid plastic, the Fun Set suits tactile and proprioceptive play as readily as it suits classroom construction time. Groups can build large-scale, huggable structures they can lean into, sit inside, or knock down and rebuild without the noise or risk associated with harder building materials, making it a natural fit for sensory rooms and calm corners as much as active group play spaces.

When it is time to pack away, the entire 300-piece set folds down into just over half a cubic metre, arriving in an environmentally friendly EcoBox. The set is available in 36 colour combinations, so schools, clinics, and families across North America can choose a palette that suits the space it is going into.

Ideal for:

• Schools and preschools setting up group building or STEM stations for multiple children at once
• Daycares and nurseries needing durable, soft-touch blocks that can be shared across a full classroom
• Occupational therapy and physiotherapy settings running group sessions that call for tactile, proprioceptive building activities
• HoReCa and soft play venues wanting a large-format activity that keeps several children engaged simultaneously
• Families building a home play corner big enough for siblings and friends to build together

• Recommended for: 4 to 8 children playing simultaneously
• Magnets per set: 6,588
• Folded storage size: just over 0.5m³
• Total pieces: 300 (228 cubes, 24 truncated cubes, 36 triangles, 12 pyramids)
