I bought these a few months ago and sadly they have already started pilling and are no longer comfortable to sleep in. Extremely disappointed with Tempur-Pedic's conduct here as well. I originally went to the flagship store in Scottsdale, AZ to get a feel for the sheets and see exactly which style I wanted. I was told by the store's manager themself that all of their sheets carry a 1-year warranty that specifically covers pilling as well as any material defects due to manufacturing. When I talked to the warranty department, though, after filing a claim, I was told that my sheets did not qualify for a replacement under the warranty.
