Using your new bunk bed is easy! First, assemble it following the included instructions. It requires full assembly, so take your time to ensure everything is put together correctly. Once assembled, you can choose to use it as stacked beds or separate them into two individual beds according to your needs. For the top bed, use a 6 - inch height mattress. Remember, the top bed is not for kids under six years old, and it can hold up to 175Lbs, while the bottom bed can support 350Lbs. This bunk bed is only for residential use. When it comes to maintenance, simply wipe it down with a clean, dry cloth regularly to keep the metal finish looking great. If there are any spills, clean them up right away to prevent staining. Keep an eye on the guard - rail and ladder to make sure they are always secure.
