My design is about children's fun furniture design that accompanies children's psychological and physical growth.I started this project because,,originally,  I thought that children’s furniture design was too singular. They were looking good in appearance, changing the size of adult furniture appropriately, and meeting simple material needs in function. I think these have not played a positive role in guiding the development of children, so I try to combine toys and furniture to allow children to display their imagination and creativity better. But after constant research and thinking, I found that simply combining the two will not perform well. Considering that children grow up faster and their psychological development is also significant, I tried to use modular splicing. Let the furniture change. This change not only changes the size of the furniture but also changes its function. Through this form, even if children multiply, they can also change the size of the furniture through splicing, which significantly saves materials. Contribute to the improvement of the environment. Besides, they can also use their own hands and imagination to change the function of the furniture and assemble them into different forms of things. This process is also interactive. Parents can also participate and let the furniture serve as a platform to promote the parent-child relationship. During this process, I realized that the choice of materials is a crucial issue. They should be able to satisfy the functional form; on the one hand; they should be safe and soft; on the other hand, they may need to be connected. Of course, the technical aspect also needs to think about, which method should be used to realize the change of furniture form is the critical point of the design. In the context of these ideas, we need to consider children’s behavior, habits, and psychological needs and design products more from children's perspective to help them grow. I think the development of imagination will be A good breakthrough point. Only when furniture is used as an intermediary to carry out various behaviors is the best furniture, because children spend a long time at home when they are young. Most of their interactions are realized through furniture, so How furniture guides them to exercise their thinking will be a novelty in furniture design in the future.
