Using this Arlo daybed is easy. First, you'll need to assemble it as per the included instructions. Once assembled, place your top mattress directly on the bed - no box spring is needed. If you want to use the trundle, you can roll it out and add a mattress up to 8 inches thick. You can use the trundle as an extra sleeping area for guests or as a storage space. When it comes to maintenance, regularly vacuum the boucle fabric to keep it clean. Avoid using harsh chemicals or abrasive cleaners on the fabric or the wood parts. If there are any spills, gently blot them with a clean, damp cloth. Also, make sure to check the assembly parts periodically to ensure they remain tight and secure.
