The “Countess” is our space saving and least costly mattress for the RV enthusiast. Wherever you roam, in the mountains or to the sea (and everywhere in between), this trailer mattress feels great. It has a foam density of 1.8-1.9 lbs. per cu. ft., which is specifically designed for the perfect balance between cost and comfort in a 5-inch thickness, where space is at a premium.

If the height above your bunk is limited, or you have limitations collapsing your pop-up for storage or transport, the “Countess” may be the RV mattress for you, as it’s only 5 inches thick. Made with high quality foam, it has a medium firmness and will not bottom out with a person weighing up to 200 lbs. With regard to comfort and durability, our “Countess” RV mattress is superior to an inner-spring mattress of the same thickness. This is definitely the mattress for you if you need to save space, and don’t want to sacrifice comfort.

This camper mattress has a sewn cover with a tape edge, just like all of our mattresses for recreational vehicles. The bottom of the mattress is skid resistant fabric so it won’t slide around, and the top sleeping surface is made from quilted damask.

The Countess is available in standard and custom sizes.

  • Best for Popups Requiring a Thinner RV Mattress—Also great for bunks and overhead cabs with limited headroom.
  • 5-Inches Thick—When 5-inch thickness is required, quality and support should not be sacrificed. The “Countess” RV mattress offers the most quantity and support given a limited thickness requirement.
  • Great Support in a Thin Design—We use a height parameter of 5 inches in a 1.8 density foam which maximizes the amount of support for your body while minimizing the recreational vehicle mattress height.
  • Durable—Our research indicates that most RVers keep mattresses for 4-6 years. We’ve designed this trailer mattress to be at its best for a minimum of 5 years.

    Designed a trundle to go with our daybed and needed a custom mattress. Called Lou and his advice on making the mattress one inch shorter made it fit like a dream. We received quick delivery and the quality is great. Our family has used it several times and the mattress is fantastic. Would definitely buy from them again…best customer service around.

    Received our Countess Mattress for my son’s bunk bed in our rv. It was exactly what we were looking for. He LOVES IT!!! The factory 2″ mattress was a joke. The mattress was custom cut for our rv, and was a PERFECT FIT!! We will be ordering a second one for the other bunk!! Thank Replacement Mattress !! 100% Satisfied

    I just ordered my second set of custom mattresses for the kids’ bunks in the RV. Ignore the pre-set sizes, because they will do any size you request. Process took less than 10 days, and they were on my front porch. Kids love the comfort and I used them the other night, and they are as good as my high-end select comfort!

    We travel quite a bit in our Motorhome. We had bought new foam mattresses for our beds at home and then I found your site for tailor-made mattresses for RV’s, I ordered one. Our mattress was a perfect fit and has been extremely comfortable.
