Claim:
A modular floor covering a substantially horizontal base comprising: a plurality of like, elongated, rectangularly-shaped floor sections, the floor sections arranged end to end in parallel rows to cover the base, each of the floor sections further comprising: a wear layer, the wear layer defining a pair of longitudinal sides and having a length and a pair of transverse sides having a width between the longitudinal sides, each of the longitudinal sides having a length and each of the transverse sides having a width, an upper subfloor layer located below the wear layer; a lower subfloor layer located below the upper subfloor layer, with a recess defined therebetween; a plurality of spacers residing between the upper and lower subfloor layers and oriented transverse to the longitudinal sides, the spacers extending horizontally outwardly beyond the wear layer on both of the longitudinal sides, a first of the spacers extending along a first of the transverse sides and located inward of the respective first transverse side, and a second of the spacers extending along a second of the transverse sides and located outward of the respective second transverse side, such that the spacers are extendable into the recesses of adjacently located floor sections on both of the longitudinal sides and on one of the transverse sides; and wherein the floor sections interconnect to one another, but are unconnected to the base during use.
