A mold is described for production of a molded element. The mold includes a first mold portion and a second mold portion engageable to define a mold cavity. The mold further includes at least one insert element having a textured surface and configured to create a first internal surface and a second internal surface opposed to one another in molded element. The textured surface may include a plurality of peak portions and a plurality of valley portions. The at least one insert element may be affixed to one of the first mold portion and the second mold portion, or is moveable with respect to one or both of the first mold portion and the second mold portion to facilitate demolding of the molded element.

One exemplary aspect of the present disclosure relates to, among other things, a tunable cushion including a core made of a polymer material, and at least one topper layer adjacent the core, which is also made of a polymer material. Further, the core and the at least one topper layer provide a cushion assembly having a support factor of less than or equal to 4 with an Indentation Load Deflection (ILD) determined using a 4 inch batt sample of the cushion assembly.
