This daybed solves a lot of our guest room challenges in that we now are able to accommodate more guests per guest room! It was easy to assemble, hubby did it by himself in roughly 30 minutes. It seems sturdy but the grandkids will undoubtedly test their trampoline skills on it during their next visit!  I bought a queen size bed and a queen size mattress fits it perfectly. The trundle is a twin, which accommodates a regular unmade twin mattress with clearance to slide underneath easily. It looks overly large! I think the sides being high make the bed over power a smaller guest room but it takes up the usual queen bed space. There is a full size bed option that would fit a smaller room better but our grown children and spouses prefer queen beds.
