The Mini Brown Stair in beechwood with a 0.7–7cm range (A062-1) offers the same scaled proportions as the standard mini version but in a beechwood construction that provides a consistent grain and weight appropriate for precise sensorial work. The 0.7cm smallest prism maintains the material's mathematical relationship across all ten pieces, preserving the integrity of the exercise at reduced scale. This version suits classrooms looking for a durable, well-finished alternative for demonstration or extension activities.
