Rainbow Stacking Arches

The rainbow brings together 8 curved wooden arches in a compact 17.5 cm format – ready for stacking, nesting and free arranging from the very first grip. Birch and MDF give each piece a clearly defined shape, while the graduated sizes create a visual order that is easy to follow during early sorting and building play. Each arch can be placed inside the next, lined up by size or rearranged on the floor into small bridges and tunnels. This simple repositioning keeps hands active and focused, as every movement calls for a fresh grip, a deliberate placement and a quick check of how the curves fit together. The colour sequence provides another concrete reference point for matching and comparing, while the 8-piece set stays manageable enough for repeated rebuilding. On a rug, a low shelf or a play table, the rainbow offers calm, action-oriented play with ever-changing arrangement possibilities. From nested semicircles to balanced rows and small scenes, the building activities that emerge connect movement, observation and imagination.
