Note: The Coastal Furniture has received several sustainability awards but performed poorly when compared with the other chairs made from natural fibres. The chair is made from eelgrass bound together with red algae (carrageenan). Those materials were familiar to the Danish designer, Nikolaj Carlsen, as they are used for roofing on the island of Læsø (in Denmark) where the seaweed-based material has demonstrated its resilience, often lasting many decades. The shell is biodegradable and is attached (using four brass brackets) to wooden legs made from recycled floorboards but is shipped fully assembled. Components need to be manually separated to facilitate composting and recycling. The weight of the chair combined with low scores for transport and end-of-life prospects resulted in the Coastal Furniture achieving a relatively poor ERPR rating.
