Wool Versus Synthetic, Honestly
Hazel Brannigan · 1 April 2026
A comparison that does not pretend one answer suits every room.
Where synthetic genuinely wins
Polypropylene is close to unstainable because the fibre will not absorb water-based liquids at all. In a room with small children or a dog, that is not a minor advantage, and no amount of enthusiasm for natural fibres makes it go away.
Nylon, meanwhile, is the most abrasion-resistant option available at a domestic price. On a staircase carrying real traffic it will outlast wool.
Where synthetic loses
Polypropylene has poor resilience, so it flattens and stays flattened, and it is prone to shading. It also melts rather than chars, which changes how it behaves near a hearth.
Both synthetics feel different underfoot in a way most people notice immediately and struggle to name. It is a temperature effect as much as a texture one.
The blend is not a compromise
An 80/20 wool-nylon blend is the most common quality carpet specification in Britain, and it is not a way of cheapening wool. The nylon adds abrasion resistance where wool is weakest while the wool provides the resilience and handling that nylon lacks.
For most domestic situations the blend genuinely outperforms either fibre alone, which is unusual enough to be worth saying plainly.
Decide room by room
The single-material house is a merchandising idea rather than a sensible plan. Wool or a blend in the living spaces, something synthetic and cheap in the utility room, and a hard floor where water is involved.
Nobody sells that as a package, which is most of the reason it is rarely what gets fitted.
The disposal end
Wool is a protein and biodegrades. Polypropylene does not, and a carpet is a large object to leave behind. Recycling schemes for floorcoverings exist but coverage is patchy and mixed-fibre products are the hardest to process.
It is not the deciding factor for most people, and it belongs in the calculation somewhere rather than nowhere.
