Please, I implore you, keep your mattress on the floor before buying this bed.  The assembly was beyond ridiculous.  The predrilled holes were unaligned and the particle board is just that- particle board.  I broke this bed thefirst night i assembled it simply trying to move it.  If  you are looking for a nice platform bed, go to Ikea and buy the Malm set.  The quality is thousands times better and the price is comprable.  3 months later, this bed is now in the dumpster.  What a waste of $200.
