Encourage creativity, coordination, and sensory exploration with Grimm’s Wankel Stacking Tower, a beautifully handcrafted wooden toy designed in Europe following Waldorf educational principles. This versatile stacking set features 10 removable triangular discs in 11 vibrant colours, allowing children to sort, stack, and build endless configurations while developing fine motor skills, hand-eye coordination, and spatial awareness. The Wankel Stacking Tower is made from sustainably sourced alder, lime, maple, and cherry wood, finished with non-toxic, water-based dyes and natural oils. The non-lacquered surfaces provide a tactile, sensory-rich experience that engages children’s sense of touch, sight, and even sound as they manipulate the pieces. Unlike plastic or metal toys, the warm wooden texture encourages repeated exploration while being naturally hygienic. The slightly rough surface also enables more stable stacking, letting children experiment with creative constructions and balance in a hands-on way. Perfect for toddlers and preschoolers, this open-ended wooden toy grows with the child. Younger children can sort and stack by colour and size, while older children can integrate the tower into imaginative play — building abstract structures, designing patterns, or creating story-based play scenarios. By combining Waldorf-inspired design, natural materials, and vibrant colours, Grimm’s Wankel Stacking Tower fosters creativity, problem-solving, and sensory awareness, making it a timeless addition to any playroom or learning environment.

Recommendation age: 1+ Materials: Alder, lime, maple, cherry wood, non-toxic water-based paint About Grimm's Grimm's toys are inspired by the principles of Waldorf Steiner and are designed with the intention of helping children discover and develop their own creativity through simplicity of shapes, leaving plenty of room for independent play and imagination. Inspired by the educational philosophies of Rudolf Steiner, Grimm's puzzles, building sets, and toys are about the rainbow, happy colors, creativity, and the imagination. There are no instructions, and you can do no wrong with a Grimm's toy. Just play, learn, and enjoy. Please note: as Grimm's uses non-lacquered wood, some paint transfer can occur during play. This is considered normal. Non-lacquered wood has a lovely texture - the rough texture of the stained wood is not only an important tactile sensory experience for children, but those rough surfaces makes it possible to build in many different ways, because the parts do not slide down so easily as the wood surface is still natural and not covered with a layer of bright enamel; however if you are concerned about paint transfer we suggest you purchase another item that is lacquered to be on the safe side. SKU: 11030 Warning: Potential hazardous accessible points. Always put on safety cap while not assembling or disassembling wooden colored discs.
