Mid-century modern style shines in this kids’ room with a walnut bunk bed, ladder, built-in shelving, and a cushioned reading nook over a mint-and-cream checkerboard floor. Peach walls, a skylit sloped ceiling, and a brass sputnik pendant brighten the space. Teal bedding, a mustard quilt, a walnut credenza with pastel drawers, and geometric wall art complete a playful yet timeless composition.
