We bought carpet from Lowes 9 months ago. The padding is the highest grade that Lowes carries. The carpet is very stain resistant but the pile is now completely flat. I vacuum slowly to pull the pile back up, but one walk on it and it's completely flat again. This is not a high pile or "nap". The problem is called "matting". Really bad and I'm disappointed. When I complained at the store they told me that the warranty is against wear and stains. NOT MATTING. So beware.
