Abstract
A synthetic multilayer floor covering has floor panels, each of which comprises at least a first and a second edge with a first and a second connecting profile, respectively. The connecting profiles are complementarily shaped so that adjacent floor panels may be coupled to one another. The first connecting profile of a first floor panel and/or the second connecting profile of a second floor panel is deformed when connecting profiles become coupled with each other. The deformation comprises a component that persists as the connecting profiles remain coupled. The persistent deformation results in stress within the connecting profiles, which are made of viscoelastic material. That material undergoes significant stress relaxation. At standard ambient temperature and pressure, the stress within the first and/or the second connecting profile decreases by at least 40% within 12 hours after the connecting profiles have become coupled.
