Ultra Soft Fitted Sheet

I purchased this to replace another torn fitted sheet. I feel the sheet is a bit thin but it was not very expensive. It is soft to sleep on, but I am concerned about durability and although the fit does cover my thicker mattress, I am hoping it doesn't start to slide off over time. When I washed it for the first time there was an enormous amount of lint on the lint filter of my dryer. I am so allergic to certain materials so I am hoping it doesn't pill up or create dust over time. This is cheap enough to have as a back up but I may purchase a thicker fitted sheet in case this doesn't hold u p.
