Single female ..one box ... lots of bits in the box . Took me a while to work out ..had to undo several screws duringthe process to make it all line up but I did it . Last piece to go on had  2 of the 4 predrilled holes missing ..but I sorted with a drill . In all about 2 hours ... partly due to only having one pair of hands ... partly as I'm not the best at diy ...but it's decent once put together and looks good .
