Using this bunk bed is easy. First, assemble it according to the instructions as full assembly is needed. Once assembled, place a 6 - inch height mattress on the top bunk and your preferred mattress on the bottom bunk. Make sure kids under six years old don't use the top bed for safety reasons. Also, ensure the weight on the top bunk doesn't exceed 175Lbs and on the bottom bunk doesn't go over 350Lbs. To maintain it, regularly check the metal frame for any signs of damage or looseness. Wipe it clean with a dry or slightly damp cloth. Remember, this bunk bed is for residential use only.
