Such a great bed!   We painted it white and did need two coats for good coverage.   It is really nice and solid and we get lots of compliments when folks ask how the bed from Wayfair worked out for us.   
We have a box spring on it for now (the set was only 6 months old so we didn't want to be wasteful and toss it so soon) and it is quite high so keep that in mind if you've got a set.  We can still get in and out without difficulty but your legs will dangle.
