What is claimed is: 1. An insulating cover, comprising: a top portion; and four sidewalls extending from said top portion, wherein said four sidewalls and said top portion have outer surfaces and inner surfaces, wherein the inner surfaces define a cavity having a cavity inner surface, wherein said four sidewalls have respective lengths parallel to the inner surfaces of respective ones of said four sidewalls and parallel to the inner surface of said top portion, wherein the cavity inner surface includes two depressions, wherein the two depressions are disposed in and extend into respective opposing two of said four sidewalls, wherein the two depressions have respective lengths parallel to the respective lengths of the opposing two of said four sidewalls, wherein the lengths of the two depressions are more than half of the lengths of the opposing two of said four sidewalls, said four sidewalls form obtuse angles with said top portion so that the cavity is smaller proximate to said top portion than distal from said top portion, wherein the outer surfaces of the opposing two of said four sidewalls include a respective two protuberances having respective lengths parallel to the respective lengths of the two depressions, wherein the lengths of the two protuberances are at least as great as the lengths of the two depressions, wherein the two protuberances are disposed at positions adjacent to the two depressions and opposite from the two depressions, resulting in a thickness of the opposing two of said four sidewalls being about the same in the vicinity of the two depressions as apart from the two depressions, wherein the insulating cover is configured to cover an attic side of the attic ceiling opening, wherein the two depressions each have a position, a size, and a shape selected to receive a substantial portion a respective side rail of a folding stair associated with an attic ceiling opening, wherein said top portion and said four sidewalls are formed from two or more separable pieces configured to be joined together at a respective two or more joining surfaces to form the insulating cover, wherein the insulating cover further comprises a joining material to join the two or more separable pieces, wherein the joining material is either a glue or a tape. 2. The insulating cover of claim 1, wherein the two depressions are spaced apart from respective corners formed between the opposing two of said four sidewalls and the top portion. 3. The insulating cover of claim 1, further comprising an extended base perimeter extending from said four sidewalls. 4. The insulating cover of claim 3, further comprising a gasket extending along at least a portion of said base perimeter. 5. The insulating cover of claim 1, wherein said top portion and said four side walls are formed from a material comprising a closed cell foam. 6. The insulating cover of claim 5, wherein the closed cell foam consists of a rigid closed cell foam. 7. The insulating cover of claim 1, wherein said top portion and said four sidewalls are formed as a single unitary piece. 8. The insulating cover of claim 1, wherein the two depressions have respective inner surfaces forming a part of the cavity inner surface, wherein the inner surfaces of the two depressions are substantially on one side of respective planes, wherein the planes lie on inner surfaces of the opposing two of said four sidewalls, and wherein the one side of the plane is in a direction away from a center of the cavity. 9. The insulating cover of claim 1, wherein the lengths and widths of the two depressions are less than lengths and widths of the opposing two of said four sidewalls in which the two depressions are disposed. 10. The insulating cover of claim 1, wherein largest surfaces of the two depressions forms acute angles with inner surfaces of the opposing two of said four sidewalls. 11. The insulating cover of claim 1, wherein the joining surfaces are flat.
