Bought this bed for my 2+ year old granddaughter.  Also purchased 12" memory foam mattress from Wayfair.  Love the style of the bed.  It is beautiful and well made.  Only flaw is, the bed comes with 3 thin slats (one at the top, one on the bottom and one in the middle) to hold the mattress.  So not possible.  If you sit on the bed the mattress sinks between the slats.  My son-in-law had to cut 6" pieces of wood to fill the spaces in.  Which basically, made it a solid and firm surface for the mattress.  This bed should be a solid piece of wood like a platform bed. The 3 smalls slats just don't do it.  Otherwise, very happy with my purchase.
