Textured materials that elevate bedroom coziness include linen, velvet, and rattan. Linen offers light, breathable softness perfect for bedding and curtains. Velvet adds plush richness in pillows or throws. Rattan introduces natural warmth through baskets, lampshades, or furniture accents, providing visual and tactile depth. Combining these materials enhances sensory comfort and layered aesthetics, transforming sterile neutral rooms into welcoming personal retreats.
