Using this bunk bed is easy. First, make sure you assemble it following the instructions carefully as full assembly is needed. Once assembled, you can place mattresses on the top twin - sized and bottom full - sized beds. The built - in ladders on each side make it simple to climb up to the top bunk. Always use the full - length guard rails for safety when sleeping on the top bunk. Remember, the top bunk has a weight capacity of 150 lbs and the bottom 200 lbs, so don't exceed these limits. For maintenance, regularly check the steel frame for any signs of wear or loose parts. You can clean the metal parts with a damp cloth. This will keep your bunk bed in good condition for a long time.
