When comparing prices, you must look beyond the surface aesthetics. Key technical factors include Pile Weight (measured in oz/sq yd), which directly correlates to durability and cost; Fiber Type, where Nylon is typically more expensive but durable, while Polyester (PET) offers better stain resistance at a lower price point; and Stitch Rate, which indicates the density of the carpet. For commercial use, ensure the carpet has a Class 1 Fire Rating and meets CRI Green Label Plus standards for indoor air quality.
