Compositions and methods for making a novel liquid gel mixture comprising at least one flexible polymer carrier, parachlorobenzotrifluoride, optional thermally-conductive materials, and optional performance-enhancing additives; using the liquid gel mixture for making surface-infused layers on layering substrates; and using combinations of surface-infused gel layer and layering substrate in cushioning foams and mattresses. Layering substrates are surface-infused with a liquid gel mixture and may be compressed to increase the penetration depth of liquid gel mixture into the substrate layer surface. This compositions may be used in mattresses, mattress topper pads, pillows, bedding products, furniture upholstery, pet beds, medical cushioning foams, seat cushions and backs, automotive foam, sports cushioning, transportation cushioning, headrests, arm rests, personal protective equipment, toys, and the like.
