Stacking and folding tables
An alternative to stacking tables are folding tables which normally use a steel leg mechanism that locks when the legs are opened and should lay completely flat when the folding table unit is closed. These are available with plywood or realwood - usually pinewood - tops or with high pressure laminate plastic facing, which is ideal if the tops are to be used for food preparation as it is easily cleaned.
The advantage of folding tables is that they take up less space when folded and can be stored horizontally or vertically making them easier to store in smaller spaces, particularly useful for tables for banqueting conferences and hotels.
