Good Carpet is best
There is nothing like walking barefoot on great carpet.
This is an area where you do not want to scrimp, but you do not
need to break the bank. I always tend to go a little over the
middle of the road on carpet. There does not seem to be much
difference between the most expensive and the upper middle
quality. Or at least much of a difference when you are out of
the show room. There is maybe a little more stain resistance or
a little softer feel that you will only notice with the two 8
inch swatches side by side. I have never been disappointed with
going that route with a decision on carpet.
I also usually chose a carpet that is a little darker than my
original decision. So that it does not show traffic dirt as
easily as a lighter choice, and it does not look as dingy as
soon.
