Third set of Temper-pedic Pima Cotton Sheets I have bought! First was for a new king size Temper-pedic mattress we bought 4 years ago - got the sheets to go with it. Needed a new set for the king size mattress. Decided to get the Pima Cotton sheets for a new mattress in the guest bedroom - the sheets are so comfortable to sleep on and they wash and wear so well, too. A little expensive for sheets compared to other brands - but I will have no others from here on!!!!!
