An office tumbler has to survive a desk, a commute and a meeting room, so it helps if it keeps coffee hot for hours, closes securely and stays quiet on a hard surface. The best ones are slim enough for a bag, easy to clean at the break room sink and tidy beside a keyboard. A mug that rinses clean in seconds makes it far easier to keep using day after day.
The six picks below include leakproof travel mugs, a temperature-control mug and a classic stainless steel cup. We have not used these products ourselves, so please confirm the size, lid type and whether the lid is truly leakproof on the current listing before you buy.

Which is best for a desk?
A stable base and a lid you can open with one hand work well. The Ember Mug 2 suits desks, while travel mugs suit commutes. Heated mugs suit long calls and quiet work.
Is a leakproof lid important?
Yes, if the mug rides in a bag. Check the listing to see how the lid seals. Test it with water before trusting it near electronics.
How long does coffee stay hot?
Claims vary, and results depend on the lid and the starting temperature. Preheat the mug for better results.
Can I use it for cold drinks?
Most insulated tumblers keep cold drinks cold, though some heated mugs are designed for hot beverages only.
