Korsö Dining Table Extension is an additional top adapted for Korsö Dining Table Large, designed by Martin Dos Santos in 2015. Made entirely of teak and suitable for outdoor use.

Korsö is named after an island just east of Sandhamn in the Stockholm archipelago. Dos Santos was inspired by the rocks that have been filed by the sea for thousands of years, when he rounded the corners of the Korsö table. The boards of the table top are placed close to each other, just like a pier that runs smoothly over the water.
