It is more particularly directed to systems, components and methods that aid early infant cognitive development, improve ventilation inside a crib, promote fresh and/or odor free air, promote thermoregulation and homeostasis, protect the person using the systems, components and methods from biological toxins, and create healthy sleeping environments for infants, toddlers, children and adults. One sleep system according to the present invention includes a cover, a core, and a bottom. The cover includes at least two raised areas. The raised areas have one or more heights ranging from 0.125 inch to 5.0 inches and diameters ranging of 0.25 to 10.0 inches. ## Claims ### Claim 1 A sleep system, wherein the sleep system comprises: a) a cover; b) a core; and, c) a bottom wherein the cover comprises at least two raised areas, and wherein the raised areas have one or more heights ranging from 0.25 inch to 2.0 inches. ### Claim 2 (depends on 1) The sleep system according to claim 1, wherein the raised areas are circular or roughly circular in shape, and wherein at least two of the raised areas have different diameters ranging from 1.0 inch to 10.0 inches. ### Claim 3 (depends on 1) The sleep system according to claim 1, wherein the raised areas are line-like areas. ### Claim 4 (depends on 2) The sleep system according to claim 2, wherein the diameters of the raised areas range from 0.25 inch to 10.0 inches. ### Claim 5 (depends on 3) The sleep system according to claim 3, wherein the heights of the raised areas range from 0.125 inch to 5.0 inches. ### Claim 6 (depends on 4) The sleep system according to claim 4, wherein the heights of the raised areas range from 0.125 inch to 5.0 inches. ### Claim 7 (depends on 5) The sleep system according to claim 5, wherein the spaces between the raised areas range from 0.10 inch to 20.0 inches. ### Claim 8 (depends on 6) The sleep system according to claim 6, wherein the raised areas have an indentation load depression rating of 10 to 50. ### Claim 9 (depends on 7) The sleep system according to claim 7, wherein the raised areas have an indentation load depression rating of 10 to 50. ### Claim 10 (depends on 8) The sleep system according to claim 8, wherein the cover comprises Lyocell and recycled polyester or other performance-based and sustainable fibers. ### Claim 11 A method of aiding infants in the development of cognitive skills, wherein the method comprises providing a sleep system for the infant to sleep on, and wherein the sleep system comprises a cover, a core, and a bottom, and wherein the cover comprises at least two raised areas, and wherein the raised areas have one or more heights ranging from 0.125 inch to 5.0 inches. ### Claim 12 (depends on 8) The method according to claim 8, wherein the raised areas are circular or roughly circular in shape, and wherein at least two of the raised areas have different diameters ranging from 0.25 inch to 10 inches. ### Claim 13 (depends on 8) The method according to claim 8, wherein the raised areas are line-like areas. ### Claim 14 (depends on 9) The method according to claim 9, wherein the method increases the CIIS score of a typical infant by at least 2.0 percent. ### Claim 15 (depends on 10) The method according to claim 10, wherein the method increases the CIIS score of a typical infant by at least 2.0 percent. ### Claim 16 A method for decreasing the CO2 concentration in the breathing space surrounding a sleeper, wherein the method comprises providing a sleep system for the sleeper to sleep on, and wherein the sleep system comprises a cover, a core, and a bottom, and wherein the cover comprises at least two raised areas, and wherein the raised areas have one or more heights ranging from 0.125 inch to 5.0 inches. ### Claim 17 (depends on 13) The method according to claim 13, wherein the raised areas are circular or roughly circular in shape, and wherein at least two of the raised areas have different diameters ranging from 0.25 inch to 10.0 inches. ### Claim 18 (depends on 13) The method according to claim 13, wherein the raised areas are line-like areas. ### Claim 19 (depends on 14) The method according to claim 14, wherein the method increases the CIIS score of a typical infant by at least 2.0 percent. ### Claim 20 (depends on 15) The method according to claim 15, wherein the method increases the CIIS score of a typical infant by at least 2.0 percent.
