The objective of this research was to produce toy products for the elderly to develop the potential in various areas of the elderly. Different types of wood materials, namely rubberwood sawn timber, plywood, and wood-plastic composites, were evaluated for their performance based on mechanical, physical, and chemical properties. Samples were compressed using a compression molding machine. The experimental results were analyzed by Analysis of Variance (ANOVA). The findings showed that all mechanical properties of the elderly toy products manufactured from rubberwood (RW) had higher strength values than those of plywood (PW) and wood-plastic composites (WPCs). The lowest water absorption and thickness swelling values of 4.36% and 2.01%, respectively, were observed in elderlytoy products manufactured from WPCs. In contrast, the minimum Ra value of 1.45 µm was observed. Additionally, the results showed that the three types of materials contain heavy metal content that does not exceed the specified standards, indicating that this product is safe for the elderly. Finally, the elderly toy products made from WPCs showed smooth surfaces, greater agglomeration, and fewer pores and voids, due to the strong interfacial adhesion between the plastic matrix and the rubberwood fiber reinforcement.
