I just found your web site and the info is invaluable. My sister has a mattress that she would love to replace with something similar. She purchased it in 1995, it was a Sealy Posturepedic Inverness PC# 0703 and there’s a bunch of other numbers of the ticket. 0939-0100 and 0939-6913 PG1555CR and 601B59. Don’t know if this means anything to you or not. My sister is about 5’8” and weighs about 200 pounds. The mattress tag also said rubberized felt and wire spring unit on it. Do you know what the replacement Sealy Mattress would be for the Inverness?
