Most of the time the original mattress that comes with your RV is horrible! I can't believe it took us this long to buy a new one but we finally did it.

Our RV mattress size is what is called a "short queen" which makes it kind of hard to shop for. Most of the stores I called did not carry this size.

We ended up buying a Lucid 10" Gel Memory foam mattress. It weighs about 54lbs and is very easy to set up.
