Is thickness a factor? 

If you have any type of restraints on thickness, such as underbed storage, or you need to be able to lift the mattress up to get at drawers under the bed we would recommend the Polar CUB or the Polar PUP for even tighter spots. It will be both light enough and thin enough to lift. If you are confident in your strength, the Polar MA is still manageable to lift, however if you are elderly or not as confident, stick with the Polar CUB. 

How to Measure your RV Mattress?

We always recommend to measure the base of the bed where the mattress sits. We don't recommend measuring the old mattress you are replacing, since it can expand or shrink over time. This skews the dimensions and will give you an improper measurement. 

In conclusion, choosing the right RV mattress size is a critical factor in optimizing your travel experience. Ensure that you measure your existing mattress space accurately and refer to this sizing chart to make an informed decision.
