MUUN MK3

A mattress built to change.

The body changes throughout your life, but most mattresses do not. MUUN MK3 is designed as a modular sleep system that can adapt as the user’s needs change. The mattress can be unzipped, allowing three comfort layers to be rearranged into six different firmness settings without tools. All while the coil system responds continuously to the body’s pressure instead of relying on fixed support zones. If a component wears out over time, it can be replaced without discarding the entire mattress.

Most mattresses are permanently glued or sealed, making them difficult to adjust, repair, or take apart. At the same time, the need for support and comfort can change with age, weight, injury, pregnancy, or a new partner. MK3 makes adaptability part of the product’s lifespan instead of a reason to buy a new mattress. Its construction includes 75% recycled steel, upcycled foam materials, and bio-based foam and has replaceable components that can reduce the need to discard the entire product when your life changes.
