Mobile bookcase features two adjustable shelves that make storing books, games and puzzles a snap. Kickplates prevent toe and finger pinching. Small objects can't get underneath. Caster brackets add triangular strength to corners where most stress occurs. Bookcase is made of Baltic birch plywood for sturdy, light-duty storage. Construction employs the dowel-pin technique, increasing already-noteworthy strength. This design leaves the thickness of the material intact where most of the stress occurs. Easy-to-clean finish is as tough as the coating used on gym floors, resists stains and won't yellow.
