Device for enhancing a corner structure

An apparatus for a corner structure, the corner structure having a horizontal surface and a vertical surface, the apparatus comprising:

• a horizontal portion having a first flat surface, a second flat surface, and a contact surface interposed between the first flat surface and the second flat surface, the contact surface having one or more contact points for resting on and supported by the horizontal surface of the corner structure;
• a vertical portion connected to the horizontal portion, the vertical portion being rigid and extending from and lower than the horizontal portion, the vertical portion having one or more contact points for bearing on the vertical surface of the corner structure;
• and
• a first interlocking pattern connected to the vertical portion, the first interlocking pattern configured to accept a complimentary interlocking pattern, the first interlocking pattern configured to suspend the complimentary interlocking pattern, the complimentary interlocking pattern being a separate and detachable piece, the first interlocking pattern comprising a first projection and a second projection spaced therefrom, a first distance between the first projection and the second projection at a first location being less than a second distance between the first projection and the second projection at a second location, the second location being closer to the contact surface than the first location;
• the portions and interlocking pattern each having dimensions and a weight such that when the one or more contact points of the portion bears against the respective surface of the corner structure the dimensions and weight of the portions and interlocking pattern maintains the bearing of the one or more contact points against at least one of the surfaces of the corner structure without fasteners.
