We were tired of trying to cover up the springs poking in our back with a memory foam topper. They made the bed way too soft. When our new foam bed arrived, we couldn't wait to get a good night sleep. When we took it out of the packaging, it grew and grew, but were able to sleep on it that night. We had no issue with odor. We just sold that camper and bought one with a king bed. We laid on the mattress at the dealership, and knew the mattress that came with it would never do. Ordered the king size right away! Love my memory foam mattress!!!
