Polyester carpet is a popular synthetic floor covering made primarily from PET (polyethylene terephthalate) — a plastic polymer often produced from recycled plastic bottles — plus advanced variants like PTT/Triexta. It is valued for softness, vibrant colour, natural water‑repellency, and affordability.

Key characteristics
• Material: Hydrophobic (water‑repelling) synthetic fibre; many options use recycled plastics.
• Feel & look: Soft, plush underfoot; takes rich, fade‑resistant colours well.
• Stain behaviour: Naturally resists water‑based spills; more vulnerable to oil/grease stains.
• Durability: Less resilient than nylon — can mat/crush in high‑traffic areas; best for low‑to‑moderate use.
• Value: Generally mid‑to‑low priced; lifespan ~5–15 years depending on use.

Pros
• Soft, comfortable feel
• Inherently water‑stain resistant
• Vivid, fade‑resistant colours
• Often made from recycled materials
• Budget‑friendly

Cons
• Prone to matting/crushing over time
• Oil/grease stains can be hard to remove
• Less resilient than nylon
• Shows wear patterns faster in busy areas

Best uses
• Bedrooms, guest rooms, home offices, formal sitting areas
• Spaces where softness and colour matter more than heavy‑traffic durability
