Cosily

The old man sat cosily by his warm stove. The fire was blazing brightly and some apples were roasting in front of it.

This brought them to the fireside, where the easy chair was drawn cosily up, and the tea things stood ready to the sitter’s elbow, the very sugar in the cup.

It's hard to put your hands into the pockets of a suit coat. Mine were tucked away cosily in the deep pockets of my zipped-up leather jacket.
