The JollyHeap Basic Set brings 100 soft, magnetic foam blocks together in one set so children can build furniture, hideouts, vehicles, and obstacle courses as their imagination leads them. Designed for 2 to 4 children to build side by side, this set gives classrooms, nurseries, small play areas, and homes across North America a genuinely open-ended way to play and construct.

Every cube and triangle connects magnetically to any block turned to its opposite pole, so builds go together, and come apart, without frustration. With 70 cubes and 30 triangles, and 2100 magnets working across the full set, there's enough here for a full afternoon of construction, from a simple tower to something closer to a small fort. At 12x12x12cm each, the blocks are sized to be sat on, stacked into furniture, or arranged into a full hideout, and 36 available colour combinations mean builds can be sorted, matched, and made visually distinct from project to project.

What's Included in the JollyHeap Basic Set

• 100-Piece Basic Block Set - Seventy cubes and thirty triangles in two complementary shapes give classrooms, nurseries, and small play areas enough pieces on hand for several children to build at the same time.
• 2100 Embedded Magnets - Every cube and triangle carries its own alternating north and south pole magnets, marked with embroidery, so pieces click together from any side and hold their shape through active play.
• 12x12x12cm Foam Blocks - Sized to be gripped easily by small hands while still large enough to form sittable furniture, crawl-through hideouts, and full-scale obstacle course pieces.
• 36 Colour Combinations - A wide colour palette supports sorting, matching, and pattern recognition, and keeps every build visually distinct.
• EcoBox Packaging - Arrives in environmentally friendly EcoBox packaging, giving schools and families a set they can feel good about unpacking and storing.

Motor Planning & Cooperative Play Skills Kids Build with Magnetic Blocks

• Fine & Gross Motor Skills - Lifting, stacking, and connecting cubes and triangles builds hand strength and coordination as children move from a simple tower to full-size furniture and hideouts.
• Spatial Reasoning & Construction Planning - Working out how vehicles, animals, and obstacle course tracks come together from just two shapes encourages children to plan ahead and problem-solve as they build.
• Cause & Effect Through Magnetic Polarity - Discovering that only opposite poles attract introduces an early, hands-on lesson in cause and effect that children can test and repeat on their own terms.
• Cooperative & Group Play - With enough pieces for 2 to 4 children building at once, the set naturally invites turn-taking, shared projects, and group problem-solving in classroom and daycare settings.
