Inquiry (采购产品): custom size box spring I am looking for a box spring for an antique bed. The size I am looking for is 7 and 1/2 to 7 and 3/4 height. the width is 45 inches and the length is 75 inches. Do you sell box springs alone? Woud you sell a box spring with a different size mattress? **** Hidden Message ***** Heidi Schoenfeld 08558 Company: N/A E-mail: heidi.schoenfeld@novartis.com **** Hidden Message ***** heidi.schoenfeld@novartis.com
