Very sturdy and just what we need to accommodate a single guest, a couple or two single guest as the beds separate completely.  The directions needed some interpretation (see pictures) part G is already attached and there are 2 packets marked A. It took less than 2 hours for my husband and I to put it together.  There are extra pieces, no worries.
Concerns:
It is lower than I expected but with a 6" mattress I guess that is to be expected.
The mattresses move on the frame.  There is nothing to hold the mattresses in place.  I will have to figure something out. I don't want me guests on the floor.
All in all I would recommend this daybed.
