Hello, I'm planning to build a loft bed for my daughter and I don't want to have support beams in the middle to allow more space in the room... my question is which beam I should use considering the weight of the beams, the bed might have up to 4 children trying to be there... how much can a 45x120 beam support or should I go with a 42x180 laminated beam or is that overkill... I am loading my simple basic Google Sketch drawing, it should be 3300 mm long with beams at both extremes. Thank you in advance for all the help
