The full sized mattress for sale is a Northwood, made in U.S.A. Less than 3 weeks old and was used by a single, mature gentleman. Sold to me as a "firm", but it is a standard type and is far too soft for my injured back. I bought an extra firm and it is great. I live in a motorhome and the item for sale has me crowded badly. I just need it gone. I paid $275.00, on a clearance sale, marked down from $350.00
