Mensa spring mattress queen size Jysk

Hi! Selling queen size mattress. Used for about a year, no damages, stains or scratches. Mattress always used with Jysk protector, so should be still good for 5 year warranty and have no stains or visible signs of usage. Price of new $599+tax. Selling for $280, I believe it is an honest price for such a good condition, but still open for your offers. Thank you!
