school storage units transform into modular sensory furniture for early childhood education

TRIMINÓ: modular furniture series for early childhood learning

TRIMINÓ is a modular furniture system designed for early childhood education environments, developed by Lais Ferraz. The project transforms conventional school storage units into interactive elements that support learning through play, targeting children up to six years old.

The system is based on a modular logic influenced by construction toys, allowing units to be combined and reconfigured. Integrated sensory features, including chalkboard surfaces, analog clocks, and letter-based handles, encourage interaction, supporting the development of motor skills, basic literacy, and spatial awareness. These elements are embedded directly into the furniture, enabling children to engage with educational content through everyday use.

TRIMINÓ was conceived for implementation in budget-constrained educational settings. Its design prioritizes accessibility and adaptability, enabling production through local manufacturing processes while maintaining consistent performance and durability. By incorporating learning interfaces into standard furniture typologies, the system contributes to the creation of more interactive and inclusive classroom environments.

furniture system for children follows a construction-toy logic

A key aspect of the project by designer Lais Ferraz is its construction method, described as ‘invisible engineering.’ The system eliminates the need for exposed metal hardware or screws, relying instead on precision joinery. Components are assembled using 45-degree miter joints and internal grooves, secured with high-strength adhesives. This approach ensures structural stability while reducing visible complexity and minimizing potential safety risks. The resulting furniture maintains a continuous, smooth surface through the application of durable laminate finishes. This construction strategy supports ease of maintenance and longevity, while allowing the technical aspects of the assembly to remain concealed.

TRIMINÓ positions furniture as an active component within educational space, combining modularity, sensory engagement, and efficient construction methods to support early learning environments.

ergonomics and autonomy: dimensions that allow children to organize their own space

sensory interface: playful handles and accessible internal storage space

design for literacy: lettered handles reinforce contact with the alphabet

spatial versatility: pieces that fit together like giant building blocks

technical minimalism: flawless laminate finish with no visible screws

pedagogical design: the integrated clock assists in playful learning of time

individual TRIMINÓ module: pure Tetris-inspired geometry for child-friendly scale

furniture as a canvas: integrated chalkboard surfaces encourage creative expression

visual contrasts: colors and textures that define functions and stimulate sight

direct interaction: the furniture evolves from static object to teaching tool

invisible engineering: technical detailing of joinery and hardware-free assembly
