My son has had this bed for 5 months and the middle support leg gave out.  It's plastic and hollow.  Replacement legs were supposed to be shipped within 2 days and here I am 3 weeks later still waiting.  Absolutely unacceptable, don't purchase this bed.  My son is not a child so he's not jumping on the bed and only weighs about 160 lbs so he's not heavy.  Just not made well.
