We bought two full size models for our home near the beach.  This was just one way we felt we could accommodate all our grandchildren, children, and friends.  They were a bit of a bear to put together as they included directions for two different models; however, they weren't terrible directions.  You need two people to assemble and it helps to have a cordless drill to finish off the slats.  Took us 3 hours to build 2 beds.  They look beautiful for the price, but I'll have to wait to see if they hold up to "10 little monkeys jumping on the bed" -- that is where I think the true test will come into play.  I think for adults sleeping on them, they'll be fine, but I'm not so sure about rigorous activity.
