Let's face it, finding the right RV mattress in your town might be inconvenient. It's probably better to call around when looking for a good RV memory foam mattress than settling for a standard piece of foam. Many custom futon stores as well as larger RV suppliers may carry RV futon mattresses and mattress toppers. You may be able to find an RV size twin mattress or RV queen mattress at a few of the suppliers but be sure to measure your bed carefully before you begin to carry out your research.
Some folks who discover the problem after making the investment in a regular camper mattress are likely to trade them in and purchase an RV memory foam mattress once they get to feel the difference. The reason is simple; there is a world of difference in the feeing.
Just think, your little RV bed will be far superior in comfort to most hotel rooms. When you get your memory foam mattress give it about 10 minutes to settle in. The material will react to your body heat and begin to conform to your shape. The best RV memory foam mattresses are usually only 8 inches, 10 inches and 12 inches thick and are very dense. They come in Full size, King, Queen and Twin.
Now imagine that you're driving for 6 to 8 hours to get to your destination and you realize that your back is starting to hurt. After setting up you are ready for bed on the first night only to find that can't go to sleep because you are so uncomfortable on a standard RV mattress. Many people have gone through this experience and have made the leap to an RV memory foam mattress for this very reason.
