Gym Matting

Judo, BJJ, and wrestling use tatami mats — typically 40mm EVA foam panels with a tatami weave surface (interlocking, non-slip). The IJF (International Judo Federation) standard tatami is 1m × 1m or 2m × 1m panels. For competition, IJF-approved tatami must be used. The entire combat area plus safety margins must be covered in tatami — typically a 10m × 10m competition area with 4m margins on each side (18m × 18m total).

FIG (International Gymnastics Federation) specifies crash mat dimensions and thickness for each apparatus. For uneven bars, a minimum 200mm landing mat directly under the apparatus plus 200mm collar mats around it. For balance beam, 100mm landing mats the length of the beam on both sides. Training facilities typically use 200–300mm PE foam mats; competition venues use 200mm FIG-approved mats with additional 100mm overlays.

Most gym mats (foam, EVA, tatami) are designed for indoor use only — UV exposure and rain will degrade the materials rapidly. For outdoor applications, rubber EPDM safety tiles or wet-pour rubber are the appropriate surfaces. Portable folding mats can be used for outdoor demonstrations or temporary setups but should not be left outside permanently.

EVA and PE foam mats have a lifespan of 5–10 years with regular use. The foam compresses over time, reducing shock absorption. A simple test: press your thumb into the mat — if it doesn't spring back quickly, the foam has compressed and protection is reduced. For gymnastics, regular compression testing is recommended. Martial arts tatami typically lasts 8–12 years.

Wrestling mats should use high-density PE or PU foam — typically 1.5–2.5 kg/m³ density for the core foam — covered by a vinyl surface that allows secure foot traction and sliding. The total mat should be 40–50mm thick for wrestling (thinner than gymnastics but firmer). UWW (United World Wrestling) has specific mat testing requirements for competition venues.
