A gymnastic floor structure comprising a panel board assembly, lower floor members spacedly secured to the bottom of the panel board assembly and placed on the gymnasium base floor, an upper floor member, and tighteners which prevent panels of the board assembly from loosening in the connecting directions, wherein the lower floor members are made of synthetic resin foam, the connectors have an almost I-shaped cross section composed of two U-shaped channels integrated back to back, one channel of the connectors is used as a fitting part between two adjacent panels, the fixing part of the connectors is fitted to the side edge portion of one unit panel board and secured with fasteners, and the fitting part is fitted to the side edge portion of the other unit panel board. The upper floor member is an elastic mat and carpet which covers the panels. The lower floor members and elastic mat are made of ethylene vinyl acetate resin foam modified by ethylene propylene rubber and butadiene rubber having an impact resilience of 50 to 60%.

A press-fitting product for a human body such as a supporter is provided. The press-fitting product includes a base material constructed of continuous foam-type latex sponge, thereby providing the product with not only elasticity and restitutive force but also with air permeability.

The disclosure relates to a floor mat and method for producing the same. The floor mat includes a plurality of tufts extending from a carrier fabric which is joined by a layer of adhesive to a backing having at least one layer of vulcanized thermoplastic elastomer. The process for production of the floor mat includes applying an olefin based adhesive to the back of a primary tufted fabric which has been preheated. The process for production includes the further separate step of applying a sheet of vulcanized thermoplastic elastomer of between about 20 and 40 mils thickness with or without a layer of reinforcing material to the preheated adhesive backed primary tufted fabric. A second layer of vulcanized thermoplastic elastomer may thereafter be applied following another heating step.
