halacha - At the seder, unsupported mid-air leaning feels awkward. In reality, how should I recline?

While performing parts of the Passover seder ritual, we're supposed to recline on our left side.

Given that we do not eat sitting on the floor, reclining on our left side on pillows (so our right hand is free to deal with the food), is there an ideal way to recline while sitting on a chair? The chair may have arms or may not. It might be large or a narrow dining room chair.
