What types of carpet show seams least?

Here is a transcription, if you prefer to read instead:

“Another question I feel people should ask more often is, “What kind of carpet can I select if seams are going to be visually a problem for me? What kind of carpet can I select so they don’t show as much?” Well, lower nap carpet, Berber carpets, commercial carpets, loop carpets, those kind of carpets, they really make the seam look really pronounced. And just because the carpet shows doesn’t necessarily mean there’s a problem with it, it just shows more.

Carpets with longer fibers, kind of fluffy carpets with longer naps, even those short shag carpets, they show the seams the least. And if those are going to be a visual problem for you, I would recommend you go with something with a longer nap like that.”
