We are selling this king size Simmons Box Springs (set of two halves) and fitting low-profile king size metal frame. We bought them new 4 years ago, they have only ever been in one room of one house. They are in great condition, no visual blemishes on the box springs or metal frame. We purchased a wooden bed set that no longer needs the box springs/frame. See pictures in craigslist ad below. Asking $20 or best offer. http://pittsburgh.craigslist.org/fuo/2678129562.html
