Types of Carpet - Carpet is constructed in several different ways, and from a variety of fibers. Understanding the strengths and difference of each will help you make the right choices for your lifestyle and budget.

Cut Pile: Still one of today's most popular constructions, cut pile achieves its durability through the type of fiber used, density of tufts and the amount of twist in the yarn. Highly twisted yarn will hold its shape longer, making it a smart choice for high-traffic areas.
DIFFERENT CARPET TYPES
1) Textured Plush - Most decoratively versatile. Textured surfaces help hide footprints and vacuum marks. Add causal beauty to any   room. Preferred style for busy households. A great "whole-house" carpet.

2) Saxony - Refined surface. Works well with traditional interiors. Ideal for living and dining rooms.

3) Friezé - Forms a "curly" textured surface because yarns are extremely twisted. Has an informal look. Helps minimize footprints and vacuum marks.

4) Plush (Velvet) - Has a dense luxurious feel. Shows footprints and vacuum marks easily. Best for low traffic areas and formal rooms.
Loop Pile

Loop Pile: Here loops are the same height, creating an informal look. This style generally lasts a long time in high-traffic areas. Many of today’s popular Berber styles are level loop styles with flecks of a darker color on a lighter background. This is a good choice for contemporary to cottage furnishings.
Multi-level loop pile: This style usually has two to three different loop heights to create pattern effects, providing good durability and a more casual look.
Cut-loop pile: This carpet style combines cut and looped yarns. It provides variety of surface textures, including sculptured effects of squares, chevrons and swirls. The multicolor effects hide soil and stains.
