Sunbrella vs Polyester Outdoor Cushions — Compared
Sunbrella vs Polyester Outdoor Cushion Fabric
Sunbrella is a solution-dyed acrylic fabric, and standard polyester is the default on many budget cushions. They look similar when new, but they age differently after a few summers of sun and rain. This guide covers where the gap shows up and when paying more for acrylic makes sense.
| Attribute | Sunbrella (Solution-Dyed Acrylic) | Standard Polyester |
|---|---|---|
| Price Impact | Generally adds cost to a cushion set | Generally the lower-cost option |
| Fade Resistance | Color runs through the fiber, so fading is slow | Often surface-dyed or printed, so it fades sooner in strong sun |
| Water and Mildew | Breathable, dries relatively quickly, resists mildew growth in the fiber | Depends on the coating, which can wear down over time |
| Feel | Softer, closer to indoor woven fabric | Varies, often slicker or stiffer |
| Cleaning | Tolerates mild soap and stronger cleaning solutions | Needs gentler care, and stains can set more easily |
| Verdict | Best for sunny, humid or long-term use | Best for shaded, covered or short-term use |
Fade Resistance
This is the biggest difference. In solution-dyed acrylic, the pigment is added before the fiber is spun, so the color goes all the way through. Polyester is often dyed after the fabric is made, so the color sits closer to the surface and can wash out under constant UV exposure.
On a south-facing patio with no cover, polyester cushions can look tired within a couple of seasons. In a shaded porch the gap narrows.
Water and Mildew Behavior
Neither fabric makes the foam inside waterproof. Both handle light rain, but what matters is how fast the cushion dries. Solution-dyed acrylic is breathable and tends to shed moisture, which helps limit musty odors.
Polyester often relies on a coating for water resistance, and that coating can wear with sun and scrubbing. Any outdoor fabric can grow mildew on trapped dirt and damp foam, so storing or covering cushions in wet weather still matters.
Feel
Acrylic usually feels softer and more like upholstery. Polyester varies a lot by weave and finish. Some of it is fine, and some feels slick or plasticky, especially on cheaper cushions. If you sit outside often, it is worth checking the fabric description on each listing.
Cleaning
Both can be cleaned with mild soap, water and a soft brush. Solution-dyed acrylic is more forgiving because the color does not lift with stronger cleaning methods. Polyester needs a lighter touch, and harsh cleaners can leave it blotchy.
Cost and Where You Will See the Difference
We sell furniture, not fabric by the yard, so the practical question is how much the fabric adds to a full set. The cheapest product on Patio Advantage is $509, and our entry-level sets starting around $500 are where you are most likely to see basic cushion fabric. In the under $1,000 range you have more room to prioritize cushion quality, and the under $2,000 guide covers sets where fabric is a bigger part of the decision.
Fabric options differ by brand and collection. Check the product listing for fabric details, and see our brand reviews for what each manufacturer is known for.
When the Upgrade Is Worth It
- Your seating gets direct sun for much of the day.
- You live somewhere humid or rainy.
- Cushions stay outside most of the year.
- You want a set to last many seasons without replacing covers.
Standard polyester is reasonable if the seating is covered or shaded, you store cushions off-season, or you plan to replace them within a few years.
Verdict
If the furniture will sit in sun and weather, solution-dyed acrylic is the better long-term value, because faded cushions are usually the first thing to make a good frame look worn. If your budget is tight and the space is protected, polyester is a sensible compromise. When a set is close to your limit, spend on the frame first and plan to upgrade the cushions later.
Common Questions
Is Sunbrella fabric waterproof?
No. It is water-repellent and breathable, so it sheds light rain and dries relatively quickly, but water can still reach the foam in heavy or prolonged rain. Covering or storing cushions in wet weather still helps.
Will polyester cushions always fade quickly?
Not always. In shade or under a roof, polyester can hold its color for a long time. The difference shows up mainly with strong, direct sun.
Can I replace polyester cushions with acrylic later?
Often yes, if the cushion dimensions are standard or you have them custom made. That makes it practical to buy a good frame now and upgrade the fabric once you see how much sun your patio gets.
