The rapid development of furniture design has changed people's lifestyle. Nowadays, customers have multiple choices of choosing products in the market. To immediately attract viewers' attention becomes the increasing challenge among designers and manufacturers. Making “fun” design is one of the strategies that could appeal customers. The topic of this thesis is to discuss the importance of combining “fun” characters to furniture design to create a strong first impression to customers. Nowadays, Human centered design (HCD) has become a trendy concept to designers. Based on this concept, I researched and designed a set of furniture, including a chair, a coat rack, two stackable stools and a coffee table. The thesis is mainly analyzing this furniture series that the way the “fun” elements are combined in its design. This set furniture is made of Bamboo plywood and Nylon rope, which are environmentally friendly materials. Moreover, Computer Numerical Control (CNC) technology, ergonomic and 3D printing technology are utilized to produce these products. Each piece of furniture includes a unique “fun” character, which can reinforce customers' first impression when they see these designs. The furniture series is designed based on functional and aesthetic aspects. I will also illustrate the way to achieve these two aspects by utilizing different material, form, and ergonomics.
