Last year I had two twin mattresses (with memory foam) made to fit out 16TBS trailer. Lightly used one season (2015) and would be glad to sell both for a total price of $100. They are fitted just for the 16TBS. My email is [a href="mailto:ellardlaw@aol.com"]ellardlaw@aol.com[/a] and live in Bettendorf, Iowa.
