Are you cursed with a concrete basement floor? Think about a natural fiber carpet and a true felt underlayer - sometimes can be found second-hand. Few other floor covering materials do much at all.
Yeah, it's concrete. The carpet is going to get thrown out anyway, I hate the color.
I'll look into the felt underpad, that sounds like a great idea.
