Purchased 2 twins for my daughters room in Dark grey. They are super cute! I only have Mattress and their is a significant Gap between mattress and headboard, because we dont currently have a box spring for their beds.  Come w just a few slats because its not intended to be that low profile euro style. But u could stick a bunkey board. And you mattress wont sink in the middle or edges.
Easy assembly.  
The Girls love not sharing a Full size bed. Worth the money not having to hear fighting EVERY night We are all Very Happy.
