When we receive a visit and it is to stay at least one night in our house if we do not have a room for guests, the most sensible thing is to have some possibility of accommodating them without being a complication for the family. In these cases there are several options that we can analyze using the furniture we already have if they are appropriate for that or with the single seat sofa bed that are found in many models at present, in different styles, as well as furniture that has a double purpose without being specifically a sofa-bed.
The sofas in the living room today, with their modern designs and natural colors, can be converted into single seat sofa bed for being versatile and comfortable just by removing the back cushions and we have beds ready to just put the sheets and the visit can rest without problem, the room becomes as if by magic in a temporary bedroom during the night.
The traditional sofa-beds are those whose design has not really changed much over the years, they are comfortable, usually large, although there are also single seat sofa bed models, they really take up more space and effectively resolve the accommodation of the visit. In these cases you can place it in the room or in a study where it serves as a normal seat and transforms when needed.
