A Guide to Material Selection for Indoor Play Castles in Kindergartens

The material selection for indoor play castles in kindergartens should be adapted to the characteristics of a closed environment. On the basis of safety, it should also take into account moisture resistance, softness and interactive experience.

Core safety indicators have been upgraded: The frame structure is recommended to be made of aluminum alloy, which is lighter than steel and has no risk of rust. The connection points should be wrapped with food-grade silicone to prevent abnormal noises caused by metal friction. High-density nylon rope is the preferred choice for climbing nets. Each strand should bear a load of over 50kg, and the mesh size should be controlled at 8-10cm to prevent children's heads from getting stuck.

Moisture-proof and stain-proof are key: The floor mat is made of PVC foam material, with an antibacterial surface that can be directly wiped with disinfectant. The seams are sealed with heat fusion to prevent water seepage. Accessories such as ocean balls and soft building blocks should be made of EVA material, which is odorless and highly waterproof. Even if stained with milk or fruit juice, they can be quickly cleaned.

The touch design is more delicate: A 3cm thick memory foam cushion layer is added to the inner side of the slide to reduce the impact force when children slide down. The inner walls of the tunnel passage are made of short-pile fabric, which not only keeps warm but also provides a comfortable tactile feedback. Meanwhile, regular ultraviolet disinfection can prevent the breeding of mites.

In addition, the selection of material colors should take into account indoor lighting. High-brightness tones such as light yellow and light blue can enhance the sense of transparency in the space, while the fluorescent color edge wrapping at the joints can serve as a visual warning, guiding children to pay attention to the turning points.
