OK I wasn’t expecting this sheet set to be as soft as it is because it’s only 400 thread count. It’s actually pretty soft and silky, but substantial. The queen fit perfectly on my queen size bed that has a thick memory foam mattress topper with no problems. I’m rethinking the use of lower thread count after seeing the exceptional quality of these sheets. I was very surprised and satisfied with the quality and durability of this set. ￼
