Perfect size for our guest room.  VERY sturdy and easy to put together.  My husband did it all by himself with just a little assistance when he needed another hand for attaching the legs. You cannot put a trundle or 'spare mattress' under the frame because it has extra legs down the middle of frame for support.  (I didn't think of that when I thought I could slide a twin mattress underneath for grandkids visits.)  I bought a 12" memory foam queen mattress which fit perfectly in the frame.
