Bijdar rugs are also known as Iron rugs of Iran due to their heavy and extremely durable nature. These rugs are some of the most sought after rugs in the United States. This unique rug uses two wefts, which makes it very heavy. They are thick piled with high knot density. They should never be folded for transportation since the solid foundations might crack; rolling them is a wise alternative while transporting. Mina Khani and Herati are the most popular patterns in this category of oriental rugs. Their unique features make them one of the finest and the most luxurious rugs available in the market.
