The cardinal difference between built -in furniture and all other types is the absence of a housing, in other words, the role of the case is performed by walls, floor and ceiling. The main advantage of this type of furniture is high ergonomics. But she has disadvantages, firstly, it cannot be rearranged, and secondly, the installation of such furniture in a place where walls sheathed with drywall are undesirable. The fastening of the shelves can and should only be carried out to the main wall. Thirdly, the price of built-in furniture is rather big, maybe even more expensive than traditional corps furniture.
