When children are involved, tables and chairs ought to be kept at the standard height of thirty inches. Return tables save room by simply eliminating the corners and drop leaf tables are nothing short of a dream come true. When ever theses tables are around with the leaves extended, it is also possible to seat up to six people at a time. Drop only one leaf and push it against the wall and four small chairs can be kept it is in place at all times. Square tables will continue to work nicely when two of the sides are placed directly into around the corner. It is simply a matter of guiding the table away from the wall membrane when it is time for a meal. More chairs can be placed in other spots around the apartment for easy retrieval when needed. Bench-style seating functions wonderfully with a small oblong table. One set of the benches can even be secured to the wall structure to offer extra safety designed for the children. When the tabletop is the same width as both these styles the seat depth of the benches, both benches are quickly gone from view.
