Simple stack of multiple fabric-covered foam pads. makes a cushy "sofa" in the playroom, and can be pulled apart for multiple sleepover guests, movie night pillows, or tumbling games, etc. (they have fabric covered foam mattresses at Jysk)
I LOVE this idea for Emilyn's room. To have a "playhouse" all the time that can grow with her - from kitchen set to a reading nook and all things in between. Definitely a look into for her big girl room!
