Once upon a time, in a city far, far away, a mobile for a child’s room was all bells, whistles, and garish colors.

But your kid is a New Yorker, and the last thing he or she needs hanging over the crib is more stimuli. Luckily, the Samara mobile by San Francisco-based Adrift — made from floaty, sculptural pieces of bent bamboo — is the perfect zentidote to city stress.

Choose whichever size (small, medium, or large) can properly combat life’s pressures and relax: It will endure through the nursery years.

Not to mention life’s later chapters.
