Almost new queen mattress for an RV but can also be used in the home. Pictures show the size compared to a regular queen mattress. This mattress was in my class B RV (over/above the cab) before I wrecked the RV. I only used ita couple of times because I was uncomfortable climbing up and down the ladder. It's a normal foam pad inside a pretty zippered cover that's machine washable. Approximately 2.5" D X 75" L X 60" W. This mattress could also be used in a Class A RV with a built-in frame. It's versatile. Compare the price on-line. I've got it fairly priced
