LUKAS – a collection of sofa beds. LUKAS is a sofa bed that comes with the-only-in-its-kind mechanism for converting the sofa into a bed. It is comfortable and easy to use - the bed frame and the mattress are hidden inside the sofa all the time. All it takes to unfold it is three simple moves. During the day, LUKAS will serve as a robust and comfortable sofa. What’s more, you can change the way it looks – by choosing one of three types of armrests. LUKAS – what counts is the interior.
