Bijar carpets are woven in Bijar, a small town in the Kurdistan region of northwestern Iran's Kurdistan Province. These carpets are very sturdy and stain-resistant. Bijar carpets are known for their sturdy knots, which ensure that the pile is tightly compressed and raised. They are knotted using traditional Turkish knots, which makes it difficult for dirt to penetrate the pile, thus extending the life of the carpet.

The defining feature of Bijar carpets is their unique weaving method. Usually, the finer the weave, the thinner the carpet, but Bijar carpets defy this convention, having an extremely thick pile despite being very finely woven. They are made on vertical looms, knotted by hand from the finest, sturdy and lustrous local wool. The knots are very tight, with up to five weft threads after each row of knots, and these weft threads are strongly hammered together.

Persian carpets from Bijar are produced in a wide range of sizes and can have a knot density of up to 600,000 knots, which speaks to the immense effort that goes into their production. Their designs are understated yet suitable for any environment, catering to a wide range of tastes.

Bijar is a town with a long tradition of carpet weaving, especially the Herati pattern, a four-leaf flower motif also known as "Mahi" (fish pattern) in Persian. This pattern has a wide range of design possibilities and can be adapted to a wide range of styles, from classical to modern.
