This bed is super solid - held my split box springs and 14.5 inch mattress effortlessly - between the mattress, 4 1/2" box springs and bed height, I am 29" off the floor which is sufficiently high enough for me even though the bed that was replaced was 36" off the floor - it's still high enough for me.  I like that you can use a box spring or just a mattress - there were 13 slats and it makes the bed solid.  Took my husband and our friend about an hour and a half to put it all together.  Highly recommend this solidly built bed and...it looks amazing!
