When the time comes to buy a new truck mattress or upgrade your RV mattress, there are a few things you need to consider, such as rig size or RV size and budget. Below, we outline the dimensions for eight standard truck and RV mattress sizes to make mattress shopping simpler for you.
36" x 80"
Size A truck mattresses are the perfect size for a Peterbiilt 579 sleeper cabin or a Freightliner Cascadia in a single or double bunk configuration.
39" x 80"
Size B truck mattresses fit perfectly in the Freightliner Cascadia, as well, and the Volvo VNL 760 or 740 sleeper cabin configurations.
42" x 80"
Size C truck mattresses are constructed to fit in some Freightliner Cascadia models, International Truck sleeper cabs, or Kenworth W990, T680, and W900 sleeper cabin options.
32" x 80"
Size D mattress, also known as the bunk size, was designed to fit perfectly in cabins with upper bunk options like the Kenworth T680 sleeper cab. Still relatively new to the SleepDog® mattress collection, size D is only currently available in our BigDawg mattress™ option, which is a 9” memory foam mattress construction.
60" x 80"
While a queen size mattress won’t likely fit into an over the road sleeper, we offer this option so you can enjoy the comfort of your SleepDog® mattress at home, too. Our queen size mattress is available in both the SleepDog® and BigDawg mattress™ options, to provide quality sleep that you already know and love.
RV Queen Size
60" x 75"
Our RV queen size mattress was developed to accommodate camper configurations, without sacrificing floor space or comfort. Available in both a 7” construction or a 9” construction, the RV queen measures slightly shorter than a traditional queen, so you can still enjoy the spacious sleep of a queen matress, without interfering with your living space.
RV King Size
72" x 75"
Simliar to the RV queen, the RV king mattress was developed for slightly larger camper and RV floor plans, so you can bring good sleep on the road with you. The RV king measures 5” shorter than a standard king, and maintains the width of a California King.
Which size is right for you?
Still not sure which mattress size will suit your needs? Then it’s time to grab a tape measure and measure your current mattress so you know exactly what size will work in your sleep space.
