Description
Trotri is a multi-functional wooden stroller that transforms into a tricycle, designed to grow with your child. It combines practicality, comfort, and durability in one evolving product. In stroller mode, parents can guide the child safely and comfortably. When the child is ready for independence, Trotri easily converts into a tricycle, encouraging exploration and motor development. The wooden structure provides strength and a natural aesthetic, while the foam seat ensures ergonomic comfort and the rubber wheels allow smooth mobility. Trotri is a long-lasting, sustainable solution that supports both parental convenience and a child’s growing autonomy.

Innovation
Trotri’s innovation lies in its dual-function design that transforms from a stroller into a tricycle without requiring separate products. The integrated transformation mechanism allows a smooth and intuitive transition while maintaining structural stability. Unlike plastic-based alternatives, the wooden body gives Trotri a sustainable, durable, and timeless character. The adjustable ergonomic foam seat ensures comfort throughout different growth stages. By combining natural materials, long-term usability, and playful autonomy, Trotri promotes sustainable consumption and reduces product waste, offering families a single evolving solution instead of multiple purchases over time.

Product Detail
Trotri is primarily constructed from solid wood, forming the main body and structural frame of the product. The wooden structure provides strength, durability, and a warm, natural aesthetic. The wheels are made of rubber, ensuring good grip, shock absorption, and smooth movement on various outdoor surfaces. The seat is made of high-density foam, carefully shaped for ergonomic comfort and support. The transformation mechanism is integrated within the wooden structure using reinforced joints and a secure locking system to ensure stability and safety during mode switching. All materials were selected for durability, safety, and sustainability, while maintaining a lightweight and child-friendly design.

Specification
Trotri is designed for children approximately 1 to 5 years old. The seat height is adjustable to adapt to the child’s growth. The handle is positioned to suit adults of different heights. Approximate dimensions: 50 cm (length), 40 cm (width), and 60 cm (height) in stroller mode. Estimated weight: 6–8 kg due to the wooden structure. Available in natural wood finish with optional painted details in soft, child-friendly colors such as sage green, beige, pastel blue, or terracotta.
