A shelving and attachment system for attaching at least one shelf to at least two adjacent and angularly displaced walls, comprising:

• at least one shelf top panel, at least one shelf bottom panel, and at least one shelf edge panel, forming at least one generally hollow shelf when assembled together;
• said at least one shelf top panel and said at least one shelf bottom panel each having a panel width congruent to one another, and a plurality of edges corresponding to one another;
• said at least one shelf edge panel extending between at least one of said edges of said at least one shelf top panel and the corresponding at least one of said edges of said at least one shelf bottom panel, and defining a corresponding at least one closed edge;
• said at least one shelf top panel and said at least one shelf bottom panel defining an internal shelf thickness therebetween;
• at least two wall attachment cleats each secured respectively to one of the at least two walls;
• said at least two cleats having heights substantially equal to said internal shelf thickness;
• said at least one shelf further including at least two open edges corresponding to said at least two cleats, with each of said open edges having a width;
• each of said cleats further having a width corresponding to said width of a corresponding one of said open edges of said at least one shelf;
• each of said cleats further having a top cleat panel, a bottom cleat panel, mutually opposed first and second end cleat panels, a cleat attachment panel, wherein said top cleat panel, said bottom cleat panel, said end cleat panels, and said cleat attachment panel comprise an open faced cleat box when assembled together;
• and
• concealed positive attachment means securing said at least two open edges of said at least one shelf to said at least two cleats and completely concealing said cleats when said at least one shelf is attached thereto.
