The carpet texture is what differentiates a Berber carpet from a plush carpet.
A Berber carpet has a distinctive loop pile that attaches to the backing and remains uncut (the size of the loops can vary from product to product). Usually, the Berber carpet comes in neutral colors with no patterns (or random patterns); they also tend to be less expensive yet long-lasting.
Alternatively, a plush carpet typically has the exposed fibers cut to the same length. Plush carpets are known as soft, inviting, easy-to-clean.
