For years I used real mattresses and box springs to create a bed for staging projects. As you can imagine storing heavy thick mattresses becomes difficult. I have found the best setup. The ZINUS No Assembly Metal Box Spring, 9 Inch White Mattress Foundation, Sturdy Metal Structure paired with The Amazon Basics Metal Bedframe risers that it rests on.

I use these metal risers and one Zinus box spring for each bed and it is a breeze to store and setup up. Just last week my two sons (12 and 10 years old) needed a bed upgrade from a twin bed to a full bed. I went to a staging sale and bought them each a bedframe. I used the Zinus box spring and purchased a full mattress to create their new rooms.
