Using this bunk bed is easy. First, assemble it following the included instructions as it requires full assembly. Once assembled, place a 6 - inch height mattress on the top bunk and an appropriate mattress on the bottom bunk. Make sure the top bunk is only used by children over six years old due to weight and safety reasons. The top bunk can hold up to 150Lbs and the bottom up to 200Lbs, so don't exceed these weight limits. For maintenance, regularly check the metal tubes for any signs of damage or looseness. Wipe the bed with a dry or slightly damp cloth to keep it clean. Remember, this bunk bed is for residential use only.
