Velvet duvet covers are typically crafted from 100% polyester, offering a plush, soft texture with a luxurious sheen. Many designs feature a dual-sided construction velvet on the topside for warmth and elegance, and cotton or microfiber on the underside for breathability and comfort. You can also choose your preferred GSM (grams per square meter); higher GSM options provide a denser, more luxurious feel. Durable and easy to maintain, velvet resists wear and, with proper care, can last for decades, gaining a timeless appeal that enhances its charm over the years.
