A floating floor system includes a plurality of floor panels, each including: a resilient base layer; a wear layer forming an uppermost surface of the floor panel atop the resilient base layer and having a higher degree of stiffness than the resilient base layer; a first locking edge portion having a first locking profile that includes a first horizontal locking feature, a first vertical locking feature, and a channel having a channel floor, being formed by the wear layer and the resilient base layer, and including a channel bed thickness measured between the uppermost surface and the channel floor, the wear layer forming at least 5% of the channel bed thickness; and a second locking edge portion having a second locking profile that includes a second horizontal locking feature, a second vertical locking feature, and a second vertical ridge and being located opposite the first locking edge portion.
