Patent ID: 8133123

Claim:
A playable surface, comprising: a relatively hard substrate with a horizontal, flat top surface, at least one layer arranged thereon of a resilient and/or damping material, and a top layer arranged in turn thereon, wherein permanent air chambers are formed in the at least one layer of resilient and/or damping material during or after arranging of the at least one layer of resilient and/or damping material, wherein a profiled mat is arranged between the relatively hard substrate and the at least one layer of resilient and/or damping material and over which the resilient and/or damping material is spread, wherein the air chambers take the form of recesses in the lower part of the at least one layer of resilient and/or damping material defined by the profile of the mat, the profile mat being manufactured from biologically degradable material or from a material with a lower melting point than the resilient and/or damping material, and wherein the air chambers are embedded only in the at least one layer of resilient and/or damping material and do not extend below the top surface of the relatively hard substrate.
