interlocking foam floor mats

Most interlocking foam mats use EVA (ethylene‑vinyl acetate) foam for the surface and core. Some listings add thin backing or film layers such as PEVA, and a few note polypropylene or vinyl surfaces or films.

Common tile sizes include about 24" × 24" and 17" × 17". Sets are offered in a range of coverage options — for example, larger kits can assemble to around 120–144 sq ft, while small nine‑tile sets measure roughly 51" × 51" (three 17" tiles by three 17" tiles).

Most mats install with jigsaw‑style interlocking edges or snap‑on border pieces that lock tiles together—no glue needed. Sets often include detachable corner and border pieces so you can finish edges, and you expand coverage simply by adding more matching tiles.

Care is usually spot clean or wipe down only. Use mild soap and a non‑abrasive cloth, then wipe dry. Listings commonly warn against submerging/soaking the mats and advise avoiding harsh cleaners, bleach, or chemical sprays.

Many sets include detachable edge and corner pieces so tiles can form finished borders or be left as open sides. Some kits explicitly include matching border pieces for a finished edge; others may require separate border tiles.

Sets are offered in a variety of counts, commonly including 4‑piece and 9‑piece starter sets, and larger kits such as 24‑tile, 30‑tile, and 36‑tile configurations—options vary by product.
