Induction cooktop mats act as protective barriers designed to keep magnetic cookware from scratching, staining, or sliding across smooth glass cooktops. Within the sub-$20 price range, products vary in size, material composition, and functional features such as thermal color indicators.
Selecting the right model depends on whether you require full-surface stove coverage, compact single-burner pads, or visual heat cues. Buyers must note that all mats in this category are designed strictly for magnetic induction stoves and cannot be used on electric ceramic, coil, or gas cooktops.
