A single set of magnetic foam blocks can occupy a corner of a playroom. This one is built to fill a room. The JollyHeap Party Set is a large-scale magnetic foam block set designed for spaces where several children build, climb, and play at once, from school gymnasiums to amusement park playrooms to busy daycare centres across North America.

Where most magnetic foam blocks are sized for a single toddler at home, this set is built around a different kind of play: eight to twelve children building simultaneously, side by side, on the same shared structures. That scale opens up group building, cooperative play, and the kind of open-ended construction that keeps a commercial or classroom play space in steady rotation rather than gathering dust after the novelty wears off.

Set Contents & Building Variety

The set includes 380 cube blocks, 40 truncated cube blocks, 60 triangle blocks, and 20 pyramid blocks, for 500 pieces in total. Each block pairs with an opposite magnetic pole, embroidered to show direction, so pieces from across the shape range can be combined into towers, tunnels, hideouts, seating, or freeform sculptures. With 10,980 magnets distributed across the set and 36 available colour combinations, builders have enough variety to construct anything from a simple wall to a full sensory play landscape.

Scale for Commercial & Institutional Spaces

Arranged as a single wall, the full set spans 108 by 672 centimetres, giving a sense of just how much building surface this set provides for a shared play area. When play is done, the blocks fold down into roughly one cubic metre of storage, an important consideration for gymnasiums, therapy rooms, or classrooms where floor space needs to be reclaimed at the end of the day.

Why Open-Ended Building Matters

Skills Children Develop with Large-Scale Foam Block Play

• Gross Motor & Coordination - Lifting, stacking, and manoeuvring larger foam shapes builds strength and body control, helping children move confidently through a shared play structure they helped create.
• Proprioception & Body Awareness - Pushing, carrying, and fitting blocks together gives children steady feedback about where their body is in space, a foundation for calm, coordinated movement.
• Creative & Collaborative Play - Building a structure with seven or eight other children at once introduces turn-taking, shared problem-solving, and communication in a genuinely playful setting.
• Fine Motor Precision - Lining up magnetic poles and truncated edges asks for small, deliberate hand movements even within a large-format build.

Ideal for:

• Schools, preschools & inclusive classrooms furnishing a calm corner or gross motor space
  
• Occupational therapy clinics & gymnasiums building group movement activities
  
• Amusement parks, family entertainment centres & soft playground operators outfitting a headline attraction
  
• Commercial & institutional buyers across Canada and the US considering a magnetic foam block set as a long-term investment rather than a one-season toy
