A functional sofa covers several aspects. During the day it looks like a normal sofa and is also used. If necessary, it can be converted in a few simple steps to a comfortable sleeping space. This will give you a fully functional bed. In small apartments, for example in the student apartment or in the first own apartment, a sofa bed is a very practical option. You save space, but you do not need to forego the radiance of a comfortable sofa. Equally useful is the purchase of a functional sofa for the guest room. The room is very comfortable. In the nursery, the functional sofa can completely replace the conventional bed or provide additional sleeping space for overnight guests. New generation sofa beds offer sleeping comfort in no way inferior to a bed.
