Why the Fuji Mat Underlay is the Ultimate Retrofit Upgrade for Your Existing Judo, BJJ & MMA Mats

If you already own a solid set of Tatami or MMA mats, you probably love the surface feel and durability. But after a few years of serious training, many gyms notice the same thing: the floor underneath just isn’t forgiving enough anymore.

That’s where the Fuji Mat Underlay shines — it’s purpose-built to roll straight under your current mats and instantly transform comfort, safety, and longevity.

What exactly is the Fuji Mat Underlay? It’s a high-density 10 mm closed-cell foam roll (1 m × 25m per roll in Australia) with a built-in moisture barrier on both sides and antimicrobial treatment. Roll it out, lay your existing mats on top, and you’re done.

Key Benefits for Retrofits

1. Instant Extra Cushioning Each layer adds 10 mm of shock-absorbing foam. One layer feels noticeably softer; two layers give you a luxurious, joint-friendly feel without changing the top surface your athletes already trust.
2. Better Protection on Throws & Hard Falls Judo players especially notice the difference on hip throws, harai-goshi, and osoto-gari. BJJ and MMA athletes feel less jarring on failed takedowns and guard passes.
3. Moisture & Odour Control The double-sided block-out barrier stops sweat and cleaning water from reaching the subfloor. Antimicrobial treatment keeps smells at bay — crucial in humid Australian climates.
4. Noise & Vibration Reduction Excellent for gyms above offices, apartments, or in multi-level buildings.
5. Super Easy & Reversible Install No glue, no permanent changes. If you ever move or upgrade, just roll it up and take it with you.

Cheaper Than Buying New Thicker Mats Replacing a 50 m² area with brand-new 40–50 mm mats can easily cost $4,000–$7,000+. Two layers of Fuji Underlay for the same area? Usually under $1,200–$1,500 installed. You keep the exact top surface your students love and still get most of the benefits of a much thicker system.

Who It’s Perfect For

• Clubs wanting more padding without a full refit
• Commercial dojos looking to extend the life of existing Fuji mats
• Facilities with concrete or wooden subfloors that transmit too much impact
• Anyone who wants to future-proof their mats against wear

Bottom Line The Fuji Mat Underlay is the smartest, most cost-effective way to give your existing mats a second life — softer landings, happier athletes, longer mat lifespan, all without the hassle or expense of a full replacement.

If your current mats feel a little “hard” these days, this is the upgrade you’ve been waiting for.
