The Marvelous 20 oz is big. You can put the largest Keurig setting on with confidence it will leave quite a bit of room in the cup for you to walk easily up the stairs without spilling your coffee on the carpet. While it cannot keep you from tripping on the cat on the way up, it is definitely peace of mind to know that you won't be cradling this baby every step of the way!
