Mainstays Basic Value Microfiber Bed Sheet Set, Rich Black, Full, 4 Piece

These are somewhat soft, super thin, and SUPER inexpensive, under $12 for a full size set, but they won't last very long and will wear through in no time. However, I put “recommend” because for my purpose, they're perfect. I bought a few sets for my child's bed to deal with a ringworm infection requiring daily changing of bedding and washing in harsh hot water every other day. I can swap these out daily and not have to worry about ruining the good sheets, and not care that they won't last long.

Couldn't understand why I was feeling sick with a continuous upset stomach and I think it has something to do with the dye in these sheets. The sheets are caked in dye. I let one of the sheets soak in water and the water was bright opaque red. I ripped the sheets off my bad, slept and actually felt better: I laid down later in the day on the sheets again and started to feel sick and lethargic again.
