Queen size IKEA SULTAN HOGLA mattress asking 220 (original 479+tax)

I'm the first owner and I bought it 1 years ago from palo alto IKEA at 479+Tax (http://www.ikea.com/us/en/catalog/products/20206905/#/70206903).
My wife and I are both very clean and no-smoker without pet. I just got graduated so I have to sale it.
It will be available on May 30 or 31. It's in very good condition, my wife and I keep it as clean as possible every day.
Asking $220, you need pick it up yourself from my apartment at Sunnyvale where is 11 miles from campus.
