How do you use the word recumbent in a sentence?

I peeked in the window and saw Dillon in his favorite armchair, recumbent and dead to the world.

The cat was asleep and totally recumbent. If I had not seen it move a few moments earlier, I would have thought it dead.

The stem of the flower laid recumbent upon the pot in which it was planted.

"The hills in their recumbent postures

Look into the silent lake..."

-Philip Larkin
