A standard queen size mattress measures 60” wide by 80”long, while the
SleepDog RV queen size mattress measures at 60” wide by 75” long. The only difference between the
two sizes is five inches of length. The RV queen size measures five inches shorter to accommodate
the smaller sleep spaces generally found in campers, RVs and travel trailers. All SleepDog mattresses
are tailored to fit the smaller space within an RV, but because every RV configuration is different, it
is important to measure your sleep space before purchasing a new mattress.
