If you have extra 15” x 80” more space available to you, this size is a better choice than Single over Single.
Single Extra Long over Queen is a perfect choice for rental properties, vacation homes, or guest room where three adults need to share a room for short term use. Ample space on lower bunk, as it is queen, airy feel, and also lots of space on top bunk.
