Fairly easy to put together. Took us about 2 hours to assemble. Bought a king and a queen, the queen was definitely easier because its a little smaller. Ive found any king bed is challenging due to the dimensions alone. 
Looks great, we wanted low profile for our old home with coved cellings, otherwise I would like something a bit taller at the headboard. Love the matte black finish, fits our Mod Farmhouse look very well.
