It keeps cooked food warm. It is not made for cooking raw food. Plate it hot, then set it on the mat.

Six settings: 122, 140, 158, 176, 194 and 212°F (50 to 100°C).

Because on a holiday the oven is still busy. While the turkey or the rolls need it, the finished dishes need somewhere else to stay warm, and the mat puts that somewhere on the table.

Two 9 x 13 in baking dishes, side by side. The heated surface is about 16.5 x 26 in (42 x 66 cm). Handles and rims add size, so measure your biggest dish before the big day.

Buy 1, get 1 50% off: with 2 mats in your cart, the second one is 50% off. Buy 2, get 1 free: with 3 mats in your cart, one of them is free. The discount applies automatically in the cart, so there is no code to enter, and you see it before you check out. The deals are on the warming mat only.

Set the timer for up to 6 hours, and unplug it when the meal is over. The controls have a child lock. Like any heated surface, keep little hands off it while it is on.

Unplug it and let it cool. The surface is water, oil and stain resistant, so spills wipe off. Then roll it up for storage.
