This hideaway trundle bed is built into an armoire unit in the main room of a studio. When closed, the bed tucks under counters in the kitchen and walk-in closet. Our guest rooms have murphy-beds, and they are genius.
I might put this built-in in my master bath without the counter top and with built-in storage cabinets above. In a laundry room hampers in a vanity for sorting dry cleaning and laundry. I'm liking that! Also love the big counter.
