This Bunk Bed is absolute perfection!!!  It took two men with construction experience about 3 hours to install, but when it was done...WOW!  It is amazingly sturdy, and well built.  I have a shore home, and get lots of family and friends down in the summer.  Two doubles with a trundle is beyond enough room to fit 5 adults or 8 kids under 12. I have had kids jump all over this piece like a jungle Jim and it's firm, sturdy, and tight.  I would recommend this bunk to absolutely anyone.  Very, VERY satisfied.
