If your Mohawk branded floor is hardwood and not plastic laminate (think formica)...then I am not at all surprised you are denting the floor. Engineered hardwood flooring is very prone to dent easily.

Thanks for the reply, glennsfc. I'm gong to look into any warranty, but I don't expect that to be at all fruitful, since we didn't install the floor. It's only a few years old.

The inner layers of the laminate floors are almost always less expensive easier to work softer woods.

Even if you put oak other hard veneer as the 'show' surface, the crappy woad behind it still dents.

Keep in mind that woods physical hardness is NOT directly related to its status as a 'hardwood' or 'softwood.'

Balsa wood & poplar are hardwoods.

Douglass fir is a softwood.

Deciduous trees vs. conifers.
