For some reason mattresses in most RVs are less than ideal. Before even spending one night in Usain we knew we needed to improve the stock offerings. The solution was to add a 2″ memory foam topper. I ordered the topper from Amazon and cut them to fit — one for each mattress and a middle section for when the “puzzle beds” are assembled each night. The middle section is rolled up and placed in a sleeping bag sack during the day.
