Rainbow Stacking Arches

The Rainbow brings 8 curved wooden arches into a compact 17.5 cm format that invites stacking, nesting and free arrangement from the first lift. Birch and MDF give each piece a defined shape, while the stepped sizes create a clear 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 turned into small bridges and tunnels on the floor. That simple change of position keeps hands active and focused, because every movement asks for a new grip, a careful placement and a quick check of how the curves fit together. The colour sequence adds another concrete cue for matching and comparing, while the 8-piece layout keeps the set manageable for repeated rebuilding. On a rug, a low shelf or a play table, the rainbow supports quiet hands-on play with room for new arrangements each time. From nested semicircles to balanced rows and small constructed scenes, the arches create a calm building activity that combines movement, observation and imagination.
