The main goal for the development of Slingerland’s work is to surprise, quiet and enlighten people. Accessibility is the most important aspect to achieve this. In his designs, Slingerland searches for forms which are universal, but also cheerful and in some cases even humorous. In some of his products, he combines industrial notions with user objects such as bowls and dishes. This can throw off the user slightly, but his designs are never incomprehensible as to their usage or meaning. Slingerland also uses a lot of colour in his designs, which ensures that the fluidity of forms and colours come out beautifully in any interior without too much trouble.
