The Explorer short queen RV mattress from Parklane Mattresses boasts seven layers and a depth of eight inches. This combination makes it the ideal mattress for long and exhausting road trips in your recreational vehicle. What sets this mattress apart from other products is that it has a Bonnel innerspring system and a built in Eurotop layer for comfort. This pillow-like layer gives the mattress a relaxing at-home feel that travelers crave when they are miles away from their bedroom. The innerspring is sandwiched between layers of high density foam, cotton felt and quilting foam with a base made of nonskid fabric to help keep your precious mattress in place.
