They didn't ship mattress supporter as add on in picture. The shipping system also not included the adds on mattress slat supporter. But the costumer services they insist on 3 wood slat which is original included is the bed i have purchased is the mattress supporter (as second picture)! If that is the mattress slat it is $200 for 3 wood slat?!. Such a lier. Had email the situation to costumer services but no body solve it.! Am living on the floor now.
