The Best Fabric for Outdoor Cushions: Waterproof, Mould-Resistant & Made to Last
- Interior design
What is the best fabric for outdoor cushions?
When choosing fabric for outdoor cushions, it’s not just about how it looks - it’s about how it performs. In the UK especially, where sunshine and showers often arrive in the same afternoon, your fabric needs to be waterproof (or at least highly water-resistant), resistant to mould, and durable enough to last season after season. But just as importantly, it should feel soft, look beautiful, and complement your outdoor space effortlessly.
In this guide, we’ll explore the best waterproof fabric for outdoor cushions, how these materials perform in real conditions, and how to choose something that not only lasts, but looks and feels beautiful too.
Waterproof vs water-resistant: what do you really need?
One of the most common questions we hear is whether outdoor fabrics are truly waterproof - or simply showerproof.
Waterproof fabrics are designed to prevent water from penetrating completely, even in heavier rain.
Water-resistant fabrics can repel light rain and moisture but may eventually allow water through if exposed for longer periods.
For most outdoor cushions in the UK, a high-quality water-resistant fabric is often the most practical choice, especially when paired with good storage habits. Fully waterproof materials can sometimes feel more rigid, whereas water-resistant fabrics tend to offer a softer, more inviting finish. Our blog, Best Outdoor fabrics for a British Summer, explains the differences between water repellent, waterproof and water resistant fabric in more detail.
What to look for in fabric for outdoor cushions
Choosing the right fabric isn’t just about whether it can handle rain - it’s about performance, comfort, and style working together.
1. Durability for everyday use
Outdoor cushions need to withstand regular use as well as the elements.
Look for tightly woven fabrics that resist wear and tear
Consider fabrics specifically designed for outdoor use
Check for strength without excessive stiffness
A well-chosen fabric will keep its structure while still feeling comfortable to sit on.

2. Resistance to mould and mildew
Damp conditions can lead to mould, particularly in shaded areas or after prolonged wet weather.
Choose fabrics designed to resist moisture build-up
Ensure cushions can dry out properly between uses
Avoid leaving cushions in consistently damp environments
This is particularly important in the UK climate, where humidity can linger.

3. Fade resistance in sunlight
Even in the UK, UV exposure can cause colours to fade over time.
Look for fabrics with good lightfastness
Consider how exposed your outdoor space is to direct sunlight
High-quality outdoor fabrics are designed to retain their colour, helping your scheme look fresh for longer.
> We love Dartmouth Outdoor fabric, a UV-resistant material available in a range of vibrant shades for adding colour that won’t fade to your outdoor living area.
4. Comfort and texture
Outdoor fabric should be as inviting as it is practical.
Softer finishes create a more relaxed, indoor-outdoor feel
Avoid overly stiff or plasticky materials
Today’s outdoor fabrics are far more sophisticated, offering a beautiful balance of durability and softness.
> We love Mullion Outdoor fabric, a soft polyester and acrylic blend that comes in a range of muted colours and adds comfort and style to outdoor areas.
5. Style and design
Your outdoor space should feel like an extension of your home.
Choose colours and patterns that complement your interior style
Mix plains with prints for a layered look
Consider how fabrics will look alongside planting and garden furniture

Can outdoor cushions be left outside?
This is one of the most important considerations for customers.
While many outdoor fabrics are designed to withstand the elements, it’s always best to think of cushions as weather-resistant rather than completely weatherproof.
Light rain and occasional showers are usually fine
Prolonged exposure to heavy rain can lead to water ingress
Storing cushions during very wet weather will extend their life significantly
A simple storage box or bringing cushions indoors overnight can make a noticeable difference.
Do outdoor fabrics go mouldy?
High-quality outdoor fabrics are designed to resist mould and mildew, but no fabric is entirely immune if left in consistently damp conditions.
To reduce the risk:
Allow cushions to dry fully if they get wet
Avoid stacking damp cushions
Store in a dry, ventilated space when not in use
If you’re concerned about mould, it’s worth reading our guide on how to deal with mould on fabric for more detailed advice.
Do outdoor fabrics feel soft or stiff?
This is where outdoor fabrics have evolved dramatically in recent years.
Gone are the days of stiff, plastic-feeling materials. Many modern outdoor fabrics are designed to mimic the softness and texture of indoor upholstery fabrics while still offering excellent durability.
This means you can create an outdoor space that feels just as comfortable and inviting as your living room.
