Upgrade your small space with this twin size 3-in-1 multifunctional pull-out sofa bed, easily converting from a single bed to a sofa to a double bed with a smooth pull-out extension—perfect for small apartments, guest rooms, kids' rooms, or home offices. Built-in dual USB charging ports (5V 2.1A+1.0A) allow convenient charging of phones and tablets while sitting or lying. Constructed with a solid wood slat base and heavy-duty metal support legs for strong stability and durable load-bearing capacity. The extendable bed stores fully under the main bed when not in use, taking only the space of a single bed daily. Delicate copper nail trims and button-tufted soft backrest add elegant, retro details.
