Is thickness a factor?Β
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 theΒ Polar CUB mattress. 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.Β
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.Β
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.

Product Specifications - MA Polar RV Mattress
Support System
We use Heat Tempered Made-in-North America pocket coil steel spring system in our support system. We add a mesh netting with bonded dura-foam to separate the coils from the comfort pillow layer. We line the perimeter of the mattress with narrow profile quantum coils for not only a good edge support, but air flow for a better cooling effect.
Cooling System
We use 3 cooling systems in this mattress. Firstly, we have cooling Ice Yarn in the quilting layer, to shed your body heat away from your body and into the rest of the mattress. Secondly, we use conductive cooling gel memory foam in the top comfort layer. This type of foam is more conductive than insultating, and ensures your body heat is conducted away from your body and into the foam. Thirdly, we conductive steel pocket coil system for the bottom support which not only allows for better air flow, it also is more conductive then a foam base.
Comfort System
While support keeps your back properly aligned and waking up with no back pain. The comfort system is responsible for relieving pressure and ensuring you don't toss and turn all night. We built the MA with 1.5" pressure relieving high density cooling memory foam. We also added a 1" layer of elastomer based light bounce foam for a soft, but bouncy feel. Put it all together, it is the perfect mix of cooling & pressure relief.
