A floating floor system includes floor panels (101), each including: a resilient base layer (123); na wear layer (121) forming an uppermost surface (103) of the floor panel atop the resilient nbase layer and stiffer than the resilient base layer; a first locking edge portion (127) having a nfirst locking profile (117) that includes a first horizontal locking feature (131), a first vertical nlocking feature, and a channel (133) having a channel floor (135) formed by the wear layer and nthe resilient base layer, and a channel bed thickness (141) measured between the uppermost nsurface and the channel floor, the wear layer forming at least 5% of the channel bed thickness. nA second locking edge portion (129) has a second locking profile (119) that includes a second nhorizontal locking feature (143), a second vertical locking feature, and a second vertical ridge n(144), is located opposite the first locking edge portion. nFigure 2An2/4 n00 n(n n01% r0 n00 |
