The Uwis bed often fits above a circular seating area.
If in doubt, measure the distance from the wall on which the U-bracket is mounted to the point where the ladder can be placed at the furthest point. If this distance is 140 cm or longer, the bed will fit and the ladder will not be an obstruction. The ladder makes a straight downward bend at the bottom so that in most cases the refrigerator door and/or toilet door can be opened normally.
