We are always attracted to wool carpets (just go to them without knowing they are wool initially). IMO there is nothing like it but I think that for wall to wall I wouldn't choose it. We have it in our bedroom (Karastan) and it has held up very well for about 20 years but unless you get spots out immediately it is difficult - that is with plain colors. If you have a pattern of course that is different and our wool orientals with patterns never show anything and will last forever! For our side porch we are going with a Karastan nylon. I hope we don't get any outgassing though.

alizacf - just wondering what brand and type of nylon carpet you had that lasted so well - I'm in the market.
