The origin of the cupboards and
wardrobes was the so-called "sleeping
shelves" firmly attached to the walls
and where people slept. Usually they
were closed by the curtain, which,
however was not useful against dust. It
is for this reason that the curtain
later was replaced by wooden doors with
hinge-plates. That resulted in
occurrence of a new types of the peasant
furniture - cupboards and wardrobes.
Originally they were tightly attached to
the wall in the hut and then it was
separated from it. It was supplied with
a back wall i.e. it started to be movable.
