In a way that provides physical or emotional ease and relaxation.

Comfortably → It is formed from "com-" (meaning with or together) and "fortis" (from Latin, meaning strong or firm) and the suffix "-ably" (meaning in a manner). The word "comfortably" means in a manner that is strong or firm together, suggesting a state of physical ease or well-being.
Think of being 'with strength' ('com-' and 'fortis') to remember that 'comfortably' means being in a state of ease.
