I had to wash it 3 times because it had a mildew smell. I am not sure it got wet or was sitting somewhere an acquired the smell. On the 3rd wash I used bleach and a hand wash cycle to let it soak. I also used a liquid fabric softener in the wash cycle and dryer sheet to give it a better smell. It finally smells better, usable and came out extra soft.
But now it doesn't even fit our "regular" king bed. It is vcccc too small from side to side.
