Verdict
Choose wool or a wool-rich blend where feel and resilience matter and budget allows. Choose polypropylene for stain resistance, easy cleaning and value in busy, spill-prone rooms and rentals. The carpet's construction and density matter as much as the fibre.
Carpet fibre matters as much as colour. The two you'll meet most are wool (natural, often blended) and polypropylene (a synthetic, also called olefin). Many carpets are blends, for example 80% wool and 20% synthetic, to combine strengths.
The right fibre depends on the room, the household and the budget. This is a feel-and-practicality decision rather than a simple ranking.
Side by side
| Factor | WoolNatural fibre, premium feel | PolypropyleneSynthetic, stain-resistant, value |
|---|---|---|
| Best for | Comfort and quality | Busy, spill-prone rooms |
| Feel | Soft, resilient and naturally springy | Varies a lot by range and construction |
| Stain resistance | Resists some everyday soiling; strong dyes and bleach can mark it | Resists many stains; some ranges are bleach-cleanable (check the product) |
| Durability | Recovers well from crushing | Hard-wearing, but can flatten in heavy traffic |
| Cost | Typically higher, especially 100% wool | Typically lower |
| Fibre type | Natural, renewable | Synthetic; recycling options vary |

Best for
Wool
- Bedrooms and lounges where feel and quality matter most
- Homes wanting a natural fibre with good crush recovery
- Where budget allows a premium carpet
Polypropylene
- Family rooms and rentals where spills are likely
- Households wanting easy stain cleaning and value
- Rooms where budget is a key driver
Potential drawbacks
Wool
- Higher cost, especially 100% wool
- Can be marked by strong dyes and damaged by bleach
- Needs gentler cleaning to protect the fibre
Polypropylene
- Can flatten in very busy areas such as stairs and hallways
- Feel varies a lot between budget and better ranges
- Less resilient than wool
Preparation implications
- Fibre doesn't change the subfloor work: both need sound gripper and suitable underlay over a reasonably level floor.
- Underlay choice affects comfort and how the carpet wears, whatever the fibre.
Maintenance implications
- Wool: vacuum regularly and treat spills promptly and gently, following the manufacturer's care guidance.
- Polypropylene: vacuum regularly; many ranges tolerate robust stain cleaning, but check the specific product's guidance first.
Fitting implications
- Both are fitted to gripper over underlay in the same way; the fibre doesn't change the fitting method.
- For stairs, the carpet's construction and suitability for stair use matter more than the fibre alone.
Questions to ask before choosing
- How busy is the room, and how likely are spills?
- Do you want a natural fibre, or is value the priority?
- Would a wool-rich blend give the balance you want?
- Is the carpet rated for the room's use, including stairs if needed?
