For overnight visitors, this daybed easily converts into a cozy sleeping space. No box spring is required - simply place your mattress directly onto the wooden slat system. Ten slats across the daybed provide sturdy support for you to rest easy. For extra sleeping space when needed, this daybed includes a roll-out trundle. The trundle tucks away completely under the daybed, taking up no additional floor space. Photo may be slightly different from the actual item in terms of color due to the monitor's display.
