Paragon's Double-Sided Wood Shelving is an excellent place to stow books and other reading materials. Constructed from a high-density, thermally fused melamine with a particleboard core, the frame has a steel brace that holds the unit together and prevents swaying. Pins and locking cams hold the laminate shelves in place, and special stops keep them from bending and prevent books from pushing past the back edge. This adder unit has only one side wall and won't stand alone, so you'll need to order a starter unit for each row of shelves. Add backing or a slat wall for an additional charge.
