A Sophisticated Sofa: Perdue Square Arm Sleeper The Perdue Square Arm Sleeper ($410, originally $669) is quite the steal. The velvet sofa has thick cushioning and a vintage look that appears straight out of the '50s. It comes in a variety of colours, but we have to admit, this light green is a favourite.
