Cotton vs. polyurethane – material comparison for garden furniture covers
Anyone who wants to protect their garden furniture in the long term will sooner or later be faced with the question:
Which material is better—cotton or polyurethane? Or is polyester better?
In this material comparison, we explain the most important differences and show
which material is really suitable for a durable garden furniture cover.
Why the material is crucial for garden furniture covers
Garden furniture is exposed to sun, rain, frost, and dirt all year round.
The covering material determines whether moisture penetrates, UV radiation causes damage, or the furniture remains permanently dry.
Cotton – natural, but limited weather resistance
Cotton is a natural material and is often valued for its breathability.
However, it has some disadvantages for long-term outdoor use. Cotton is only suitable for indoor use, if at all. For outdoor use, even in covered areas, cotton is definitely the wrong choice.
- absorbs moisture quickly
- dries slowly
- susceptible to mold and rot
- not completely waterproof
Polyurethane – a modern solution for maximum weather protection
Polyurethane (PU) is a high-tech material that has been specially developed for outdoor use.
It offers significantly better protection against the elements.
- completely waterproof
- high UV resistance
- robust and durable
- easy to clean
