Furniture Design Planck Coffee Table by Kristof De Bock The table is made of different pieces of plywood that are glued together under pressure. The surfaces are sandpapered and threated with a matt and very strong varnish. There are 2 levels -since the inside of the table is hollow- which is very practical for placing magazines or plaids. Under the table there are build in bullet wheels. So the gap between floor and table is very small, but at the same time, it is easy to move. The way the plywood is used (vertical) makes it very strong.
