These are a very affordable option and a great look. They are a flat woven rug that come in many different styles. So if you are budget conscious, or maybe there's an area of your home where you are height concious (maybe right under a door swing?), these could be this area rug for you.
Tufted rugs are a great compromise because they are typically made of quality products, such as wool, but because the manufacturing process isn't too intense, they are generally reasonably priced. They are created using a tufting gun, where the wool fibers are looped in and out of a backing into a pattern and then sheered into a cut pile.
These are created on a loom, and because of this, they can be stocked with many different colored yarns. Both loop pile, aka berber, cut pile rugs and a combination style can be made this way. The loom is the oldest known rug making technique, and continues to be a means of creating beautiful area rugs.
Kilims are produced by tightly interweaving the warp (vertical) and weft (horizontal) strands of the weave to produce a flat surface with no pile. These rugs are not the most durable, so make sure you place them in a low traffic area.
