My college student son who is leaving the dorm and furnishing a bedroom wants Ikea's Malm bedframe and seeks inexpensive but good looking underbed storage for it. He is intrigued with Ikea's coordinated underbed storage boxes that roll out easily on casters, but they are a reach for his budget ($75 per pair, new, ). The Malm bedframes are readily available on Craigslist (which he'll take advantage of), but not the boxes.

Are there any good substitutes? Rolling underbed storage boxes abound on the market, many made of clear plastic, but I think he wants something that looks more coordinated to the bedframe, probably dark and sleek.
