Located in the city of Busan in the south-east of Korea, DUT Korea was founded in 1992 by Yong Chai Jung, an ex-military mechanical engineer. The company works closely with a number of local universities in the bustling town.

The light engineering business has devised a continuous foaming process that enables foam with six or seven different densities across a block to be produced. Typically, the foam will be denser where the greater pressure is put on the mattress, at the shoulders and hips.
