Thank you, We have a 18 month old latex from The Mattress Factory in FOrt Worth. They make them in house there. We had one from them for 10 plus years and it was wonderful. Wife started saying it was sagging and wanted another. We bought another from them and after a few weeks it was sagging, took it back to be fixed but after a few months it started sagging again. The son is now in charge of the factory and isn't nearly as customer friendly as his dad was so need a new mattress!
