ErgoCrafted HeatMat Pro Mug Warmer

Coffee has about a twelve-minute window before it slips into lukewarm and sad. The HeatMat Pro keeps it in the good zone. Set your cup down and the gravity sensor switches the plate on by itself; lift it off and it powers down on its own.

The heating surface is wide and flat, not the tiny puck most warmers use, so a mug, a glass, or a wide tumbler all sit flush and heat evenly. Worth knowing up front: it's built to keep a hot drink hot, not to reheat one that's already gone cold.

• Gravity sensor turns on when your cup lands and off when it leaves
• Large flat plate fits mugs, glasses, and tumblers
• Steady, constant warmth for coffee, tea, or cocoa
• Minimalist matte finish that suits any desk
