Fluff it in the dryer

I purchased this for a twin bed in the spare room. It has a very cheap mattress.This mattress cover arrived in a vacuum sealed bag. I unpacked it and let it rest for 24 hours as directed by another reviewer. I was NOT impressed. It was still flat in most places. Well, before I returned it I decides to fluff it in the dryer, WOW, was I impressed! It looked just like the picture. I then placed it on the twin bed and tried it out that night.. It made the world of difference. Very comfortable.
