There's nothing boring about Cube. You can easily change the shape of the Cube in just one simple action. A low armchair with a matching ottoman, a handy comfortable mattress for overnight guests or a high ottoman.

Design by Joseph Willet for Karup Design.


The filling in the mattress is mainly made of recycled cotton and tested according to TÜV, which means that quality and environmental standards are met. To arrive at recycled cotton, cotton from worn clothing or cutting waste is used. The big advantage of recycling is that the impact on the environment is many times smaller than with organic or regular cotton without losing the comfort properties.
