Using this twin bed with a pull - out trundle is easy. First, assemble it following the included instructions. Since it requires full assembly, take your time to ensure all parts are properly connected. Once assembled, place your mattress on the bed frame. You don't need a box spring. For the trundle, just roll it out when you need the extra bed for guests or sleepovers. The bed frame can hold up to 220 lbs, so make sure not to overload it. As for maintenance, use a soft, dry cloth to clean the solid wood surface regularly. Avoid using harsh chemicals or abrasive cleaners as they can damage the wood. Keep the bed in a dry environment to prevent the wood from warping. When not using the trundle, roll it back under the main bed to save space. And always select the right color, size, and other options according to your needs when ordering, as you'll receive the exact product based on your selections.
