The floor member has a top surface for walking upon and a bottom surface for placement on a floor base as part of a floating floor installation. The floor member includes a flexible plastic main substrate layer that is sandwiched between a flexible plastic wear layer and a bottom portion formed of meltable adhesive material. The meltable adhesive material has an exposed bottom surface that is the bottom surface of the floor member. The exposed bottom surface is non-adhesive and non-tacky at normal room temperatures. The meltable adhesive material has frictional properties that enable the floor member to resist manual sliding movement on a floor base but still permit manual sliding movement, thereby providing the floor member with positional stability when placed on a floor base as part of a floating floor installation.
