Stays flat, drains fast, and doesn't curl at the edges over time.
Wet tile and enamel are some of the most common places for a fall to happen, and cheap mats that curl at the edges or trap water can end up making things worse rather than better. This one is covered in hundreds of small suction discs and drainage holes, so it grips the floor and clears water instead of pooling it underfoot.
Give it a wipe-down or rinse weekly — the holes that drain water can also collect soap residue over time.
