In the den, an L-shaped Lee Industries sectional creates a cozy niche in front of Shaker-style paneling by Custom Cabinetworks. Plush pillows in a mix of motifs—among them, Zak+Fox’s Cloudband cotton-linen and a Ralph Lauren for Kravet tartan—boost the room’s cozy quotient while Kelly Wearstler’s Alta table lamps for Visual Comfort & Co. enhance its masculine mood.
