An extension for a shelf, the shelf having a substantially planar top surface, a plurality of holes in the top surface, and a front edge. The extension includes a substantially planar shelf portion having a front, back, and left and right sides. The front of the planar shelf portion has a curved portion between the left and right sides. A plurality of downward extending tabs are under the planar shelf portion and are arranged in alignment with corresponding holes in a shelf. A lip extends downward from the curved portion of the planar shelf portion. When the extension is installed on a shelf, the tabs engage the holes in the shelf and the planar shelf portion is substantially parallel with and on the planar top surface of the shelf and the lip is positioned in front of the shelf front lip.

1. An extension for a shelf having a substantially planar top surface, a plurality of holes in the top surface, and a front lip, having a front edge, the extension comprising:a) a substantially planar shelf portion having a front, back, and left and right sides, the front of the planar shelf portion
1. An extension for a shelf having a substantially planar top surface, a plurality of holes in the top surface, and a front lip, having a front edge, the extension comprising:a) a substantially planar shelf portion having a front, back, and left and right sides, the front of the planar shelf portion having a curved portion between the left and right sides; b) a plurality of downward extending tabs under the planar shelf portion, said tabs being arranged in alignment with corresponding holes in a shelf; c) a lip extending downward from the curved portion of the planar shelf portion; and d) a clip for engaging a shelf front lip; wherein when installed on a shelf, the tabs engage the holes in the shelf and the planar shelf portion is substantially parallel with and on the planar top surface of the shelf and said lip is positioned in front of the shelf front edge.2. The extension of claim 1, wherein the tabs are positioned along the back of the planar shelf portion.3. The extension of claim 2, wherein the tabs extend downward and to the back of the planar shelf portion.4. The extension of claim 1, wherein the tabs prevent upward movement of the back of the planar shelf portion relative to the shelf when the tabs engage the holes in the shelf and the planar shelf portion is laid in substantially parallel alignment on the planar top surface of the shelf.5. The extension of claim 4, wherein the tabs further prevent forward and backward movement of the planar shelf portion relative to the shelf when the tabs engage the holes in the shelf and the planar shelf portion is laid in substantially parallel alignment on the planar top surface of the shelf.6. The extension of claim 1, further comprising one or more stiffening members positioned under the planar shelf portion.7. The extension of claim 6, wherein the one or more stiffening members are substantially parallel to the front to back axis of the planar shelf portion.8. The extension of claim 7, wherein when installed on a shelf the back of the one or more stiffening members contacts the shelf front lip.9. The extension of claim 1, wherein the width of the extension is substantially the same as the width of the shelf.10. The extension of claim 1, wherein the curved portion is a convex curve.11. The extension of claim 10, wherein the convex curve extends substantially along the width between the left and right sides.12. The extension of claim 1, wherein when installed on a shelf the ends of the lip engage the shelf front lip.13. The extension of claim 1, wherein the lip extends downward and substantially perpendicular to the planar shelf portion.14. The extension of claim 1, wherein the installation on a shelf does not require tools or separate hardware.15. An extension for a shelf having a substantially planar top surface, a plurality of holes in the top surface, and a front lip, the extension comprising:a) a substantially planar shelf portion having a front, back, and left and right sides, the front of the planar shelf portion having a convex curved portion extending substantially along the width between the left and right sides; b) a plurality of tabs extending downward and to the back of the planar shelf portion, said tabs being arranged in alignment with corresponding holes in a shelf; c) one or more stiffening members under the planar shelf portion, said one or more stiffening members being substantially parallel to the front to back axis of the planar shelf portion; and d) a lip extending downward from the curved portion of the planar shelf portion; wherein when installed on a shelf, the tabs engage the holes in the shelf and the planar shelf portion is substantially parallel and on the planar top surface of the shelf and said lip is positioned in front of the shelf front lip such that the ends of the lip engage the shelf front lip, and the installation does not require tools or separate hardware.16. A shelf extension, comprising:a) a substantially planar shelf portion having a front, back, and left and right sides, the front of the planar shelf portion having a curved portion between the left and right sides; b) means for attaching the planar shelf portion to a shelf and preventing upward movement of the back of the planar shelf portion relative to the shelf; and c) a lip extending downward from the curved portion of the planar shelf portion, wherein when installed on a shelf having a shelf front lip, the ends of the lip engage the shelf front lip. 17. An extension for a shelf having a substantially planar top surface, a plurality of holes in the top surface, and a front lip having a front edge, the extension comprising:a) a substantially planar shelf portion having a front, back, and left and right sides, the front of the planar shelf portion having a curved portion between the left and right sides; b) a plurality of downward extending tabs under the planar shelf portion, said tabs being arranged in alignment with corresponding holes in a shelf; and c) a lip extending downward from the curved portion of the planar shelf portion; wherein when installed on a shelf, the tabs engage the holes in the shelf, and the planar shelf portion is substantially parallel with and on the planar top surface of the shelf, and said lip is positioned in front of the shelf front edge, and the ends of the lip engage the shelf front lip.18. The extension of claim 17, wherein the width of the planar shelf portion is substantially the same as the width of the shelf.19. The extension of claim 17, wherein a substantial portion of the lip is curved.20. The extension of claim 17, wherein the curve of the curved portion is defined by a single radius.21. The extension of claim 17, wherein the lip comprises a homogenous continuum of material from one end of the lip to the other end of the lip.
