Full pine (no MDF), not the greatest carpentry but sufficient.
Not too hard to put together (they say its a two man job but you can manage on your own).
Blind screw sockets needed clearing with a screwdriver.
Slats are screwed in by hand with not pilot holes which might complicate taking it down and putting it back up again.
The mattress is emitting a lot of chemical smell (72 hours rest is suggested on the packaging, but you will want to leave it longer). Might be worth just buying a normal single mattress.
