Guidecraft Discovery Stackers - Rainbow Arch

Each set includes five solid, arched pieces in graduated sizes, plus double-sided inspiration cards. The cards offer play ideas, relevant vocabulary and imagery to guide building. The largest arch measures roughly 8.1 inches long, 2.8 inches wide and 3.9 inches high, giving children plenty to balance, nest and stack into their own creations.

Like a classic wooden rainbow, the Rainbow Arch invites open-ended balancing and stacking, but its curved arches focus on organic geometry rather than tall nesting alone. The extremely resilient pieces hold up to indoor and outdoor play, so children can build bridges, tunnels and freeform shapes on a table or the floor.

The set is suggested for children two years and up. At this stage builders start to explore relationships in balance and shape, and the curved arches encourage them to test how pieces lean, stack and support one another. Older children extend play by combining arches into more complex constructions.

Yes, the arched pieces bring a fresh look to light play, casting curved shadows and colour across the surface. The set comes in either a gradated, nature-inspired palette or vibrant rainbow tones, so the way light and colour interact changes with the shapes children choose to arrange.

It is. The pieces are extremely resilient and durable, so they suit the classroom, playroom, backyard or garden. As an upgrade from the classic nesting toy, the set bridges gaps between different play patterns, moving from quiet tabletop balancing to active building wherever children gather.

Each set comes with double-sided inspiration cards packed with ideas for play, relevant vocabulary and clear imagery. They give parents and educators a starting point, then encourage children to invent their own arrangements, name the shapes they make and describe how each arch balances against the next.
