Pillows can invite a cozy snuggle or inspire better posture. They can complement, pop or intimidate, and can even deceive. I knew a loveseat with the power to seduce the most upright guest into tucking legs under and cuddling one of its massive pillows. But Auntie’s creaky antique chair has a propped pillow that discourages heedless plopping-down. Hint: some guests appreciate a small, firm lumbar pillow for support during your tete-á-tete over tea and scones (or wine and warmed peaches-brie, or beer and chipotle-chips). Other uses: clutch one late at night while watching zombie movies on your tablet.
