The carpet should be ok, it is taking quite awhile to lay flat.  It was delivered rolled up very tight the end of the carpet that was inside the roll was very wrinkled.  I put some heavy boards on that end to flatten it out, that worked somewhat but the edges are still wrinkled after six days.  It may lay flat with time, we'll see.  The solution for future deliveries would be to roll carpets on a 6 inch cardboard tube instead of bending the inside end so severely and rolling such a tight radius.  This would probably cost an extra $5 or $10 but worth it.
