Doormat used to clean shoes when entering indoors is often made of polyester, generates microplastics, contributing to environmental pollution. Luffa, a plant-based fiber is quick to dry and lightweight. Even after its life, it naturally decomposes as a biodegradable material. When layered, it creates volume and an attractive form.

oyster buoy was produced by replacing the plastic buoys used in the marine industry with oyster shells. Even if it is damaged during use and can no longer function as a buoy, it sinks into the sea and provides a place for marine life as an artificial reef. Made from oyster shells(calcium carbonate) and cement, it doesn't release toxic materials into nature. In other words, oyster shells become the material for this buoy, which then becomes an artificial reef to provide a habitat for marine life; thus creating a sustainable virtuous cycle.

As a furniture designer, I began Bubble Bound Bench project thinking about what I could do for sustainability and whether there was a material that could replace the leather I often used. I thought about true furniture and materials that were appropriate for the times. I combined eco-friendly Korean paper leather and raw wood to design a bench using the bubble wrap - which once was used to wrap the original material - as a fabric filler. In addition, I was inspired from the fact that discarded sofas and chairs that cannot be easily replaced when the fabric is damaged, and I made it easy for users to replace the fabric through the process of directly tying and loosening the bench strings.
