FLAP manages to contain two beds in only 35 cm of depth and 214 cm of height. The foldaway beds of the FLAP model manage to contain two large single mattresses up to a height of 18 cm. The upper bed is secured by a slightly inclined iron staircase with rectangular section steps to facilitate getting on and off the bed. Always the upper bed can be completed with protections on all open sides in order to guarantee absolute safety. It is also equipped with a mechanism to allow the easy remaking of the upper bed without using the ladder. As for the lower bed, it is supported by iron feet and both are assisted by gas pistons which also slow down the descent during the opening phase. Furthermore, FLAP can also be only upper bed or only lower bed according to requirements.
