We've finally chosen the laminate-maker — Wilsonart. Unfortunately, the only site that carries the model we want, does not carry Wilsonart's brand of padding. All they offer are some no-name choices.

My (much) better third insists, that she wants everything to be from the same brand, while I can't see, what's the big deal about underlayment and would happily take whatever is available on the same site.

Is the choice of padding really that important? The floor in question is in the basement (no need for sound-insulation), on a very thick layer of concrete (no moisture from below, really, although the air above could be humid).

Thanks for any advice!
