Patterned carpet now accounts for over 90% of commercial carpet installations, especially in high profile locations. The broad array of available styles and customized treatments defies description. Designers and facility managers know that patterned carpet has practical and aesthetic benefits. Functionally, patterns conceal seams, hide traffic lanes and wear, disguise stains and faded areas, and are easier to patch if damaged.Visually, patterns have evolved beyond the simple pin dots of yore to include intricate geometrics, free flowing waves, texture on texture, and truly custom design, not just custom color. Because many interior designs use the floor covering as the starting point for coordinating other finishes, patterned carpet creates exciting new design possibilities for commercial spaces.
