In a refrigerator having a storage compartment with a rear wall and a pair of elongated ladder tracks secured to the rear wall in a spaced apart vertical orientation;

• a shelf assembly including:
• a pair of shelf supports, each of said supports including a base portion removably secured to a corresponding one of the ladder tracks, a generally vertically oriented wall extending forwardly of said base portion within the compartment and a flange projecting generally horizontally inward of said vertical wall, so that said shelf support flanges are disposed in a spaced apart relationship within the compartment;
• a rectilinear imperforate shelf member with an upper surface, an under side and spaced apart front, rear and side edges;
• a rim structure encapsulating said shelf edges;
• said rim structure comprising an upper member and a lower member joined together around said edges of said shelf member;
• said upper rim member including a main body portion engaging the upper surface of said shelf member along said shelf side edges;
• said lower rim member including a main body portion supporting said under side of said shelf member along said shelf side edges and resting on each of said horizontally projecting support flanges and including a flange projecting downwardly inside each of said horizontally projecting support flanges to assure non-binding sliding movement of said shelf on said supports;
• and
• each of said support flanges including a downwardly extending inner edge portion and said lower rim member flange projecting downwardly adjacent said inner edge portion to maintain said shelf aligned on said shelf supports.
