Abstract

A panel having a core and at least two opposite edges with coupling parts at two opposite edges. The coupling parts of the panels can be coupled to each other by means of a downward movement, such that a locking is obtained in the plane of the panels and perpendicular to the edges, as well as perpendicular to the plane of the panels. The coupling parts at the two edges comprise locking parts ensuring locking in the direction perpendicular to the plane of the panels, and at least one of these locking parts forms part of a flexible portion made in one piece with the core. The flexible portion is bendable at least in the plane of the panel. The panel includes at least one support portion which forms a support against bending of the flexible portion in a direction transverse to the plane of the coupled panels.
