I have been buying sheets from Overstock for several years! You can not beat the comfort of sheets from 300 to 600 thread count. Higher than that is over kill and under that you can go to the department store. The sheets are very comfortable but do have a tendency to make you warmer.They hold the heat. Excessive washing will cause the sheets to develop knots. Buying several sets and rotating them makes you forget about that problem. Only shortcoming is they don't offer extra sets of pillow cases.
