You might not think of Pottery Barn's Upper East Side little sib PBteen for your child's first rug, but you should. Florals, stripes, dots, textures and shags come in eye-pleasing colors, squishy piles and patterns that'll suit you both long past the preschool years. New: a supersoft "Ultra Plush" wool number that promises to induce napping instantly. Your too-cool-for-school tween will, of course, like the loot here too—unless she or he has moved on to more sophisticated city shops like Design Within Reach.
