These are hands down the best set of sheets I have ever owned.  They are worth the money.  They are very high quality and so soft.  I love these sheets.  Even though they are thicker we still use them in summer.  I bought the 800 thread count of the same sheet for summer and it does not even compare.  Don't waste your money on those.  The price is not that much cheaper.  I wish I had purchased another set of the 1500 thread count but I thought I'd save a little money and they would be lighter.  They are lighter but the softness is not there.  You won't regret buying these.  One note:  since they are thicker, you will need a high capacity machine to wash the top and bottom sheet at the same time.  I have a high efficiency washer and I was able to wash them both with no problems.  If you have an older washer you might have to wash each piece separate.
