Outdoor cushion fabric is the single component on a patio set most likely to fail first. The frame and the structure can last 15 years while the cushions look terrible by year three because of a fabric choice that cost the manufacturer 20 dollars instead of 60. The good news is that the fabric on most outdoor furniture is replaceable, and the decision is mostly about matching the fabric grade to your local UV and your willingness to maintain. The three fabrics that dominate the 2026 outdoor market are acrylic (Sunbrella and similar), olefin (also called polypropylene), and polyester. Each has a clear strength and a clear weakness.
How Sunbrella and acrylic work
Sunbrella is the brand name of Glen Raven Mills’ solution-dyed acrylic fabric. The fiber is polyacrylonitrile, extruded with pigment already dissolved in the molten polymer. The result is fabric where the color is the same all the way through every fiber, not just on the surface.
This matters for UV resistance. UV radiation breaks chemical bonds in dyes, fading the color over time. With surface-dyed fabric, the colored surface fades while the fiber underneath remains white, producing the chalky, washed-out look you see on three-year-old patio cushions. With solution-dyed fabric, the dye that fades is replaced by identical-color dye below it, so the visible color stays consistent for far longer.
Sunbrella’s published colorfastness rating is 1500 hours of accelerated weathering with no significant color change. Polyester typically rates 200 to 400 hours. In real-world UV exposure (full sun, southern US), this translates to roughly 8 to 10 years of color retention for Sunbrella versus 2 to 3 years for polyester.
Sunbrella also resists mildew with an integral coating that lasts the life of the fabric (versus mildew-resistant treatments that wash off after a few cleanings). The fabric breathes well, dries quickly, and feels reasonably soft against bare skin.
Cost is the catch. Sunbrella fabric runs 30 to 80 dollars per linear yard wholesale, versus 5 to 15 dollars for polyester. A replacement cushion set for a four-person dining set in Sunbrella costs 600 to 1200 dollars; the same set in polyester costs 200 to 400 dollars.
Acrylic alternatives include Outdura, Sattler, and Phifertex (the woven mesh). These are equivalent in fiber chemistry and lifespan but typically priced 10 to 30 percent lower than Sunbrella.
How olefin (polypropylene) works
Olefin is solution-dyed polypropylene. The fiber chemistry is different from acrylic but the dyeing method is similar: pigment mixed into the molten polymer before extrusion. Color retention is comparable to acrylic for the first 5 to 6 years, then declines slightly faster.
Olefin’s strengths are stain resistance and price. Polypropylene is hydrophobic (does not absorb water), so spills bead up and wipe off instead of soaking in. Wine, coffee, ketchup, and oil all wipe off olefin without staining. Acrylic stains more readily and needs more aggressive cleaning. Polyester stains worst.
The downside of olefin is heat resistance. Polypropylene has a low melting point (around 165 degrees C, versus 250 for acrylic). On dark-colored olefin cushions in direct desert sun, surface temperatures can reach 70 to 80 degrees C, which is below the melt point but high enough to cause subtle fiber distortion over many seasons. Light-colored olefin avoids this. Dark Sunbrella in the same conditions handles the heat without issue.
Cost: 12 to 30 dollars per linear yard wholesale. A replacement cushion set for a four-person dining set in olefin costs 300 to 600 dollars. This positions olefin as the value pick: 80 percent of Sunbrella’s lifespan at roughly 50 percent of the cost.
Brands worth knowing: Revolution Fabrics (Performance Textiles, mostly indoor but their outdoor-graded olefin is excellent), Crypton Outdoor, and most house-brand performance fabrics at retailers like Crate and Barrel or West Elm.
How polyester performs outdoors
Polyester is the budget default. It is what comes on almost all sub-1000-dollar patio sets at big-box retailers. The fiber itself is durable, but it is almost always surface-dyed rather than solution-dyed, which means color fades fast.
UV is the killer. In full Phoenix or Miami sun, polyester loses 30 to 50 percent of its color saturation within 18 to 24 months. By year three, dark colors look gray and red looks orange. The fabric structure is fine, but the appearance is gone.
Mildew is the other concern. Most polyester outdoor cushions have a sprayed-on mildew resistance treatment that washes off after the first few cleanings. Once gone, the fabric will mildew in humid climates within weeks of staying wet.
Some polyester is solution-dyed and rated for outdoor use. These products perform much closer to Sunbrella in colorfastness, but cost approaches Sunbrella as well. Solution-dyed polyester is uncommon at retail; you generally find it on direct-to-consumer outdoor furniture brands that specify their fabric grade.
Cost: 5 to 15 dollars per yard for surface-dyed polyester. The economics work for short-term needs (rental property, vacation home with light use, kids’ play area) or for shaded patios where UV exposure is limited.
Fill matters too
The fabric is half the story. The foam inside is the other half. Three common fills:
Closed-cell foam: absorbs water slowly but releases it even more slowly. Once wet, takes days to dry. Mildews if not flipped or aired out. Cheap.
Open-cell polyurethane foam: absorbs water freely, dries in 12 to 24 hours in good air flow. Standard fill on most patio cushions.
Quick-dry reticulated foam: large open cells that drain water within minutes. Stays out in rain without issue. Premium fill, usually paired with Sunbrella cushions. Look for terms like “DryFast” or “Quick-Dry” in the product description.
For cushions that live outside year round (uncovered storage), specify quick-dry reticulated foam regardless of fabric.
Climate fit
Hot sunny climates: Sunbrella is the only fabric that holds up cosmetically beyond five years. Olefin is acceptable if you accept some fading by year six or seven. Polyester is a poor fit; budget for replacement every two to three years.
Humid hot climates (Gulf Coast, Florida, southeast Asia): mildew resistance is the dominant factor. Sunbrella and acrylic both have integral mildew protection. Olefin’s hydrophobic nature also resists mildew well. Polyester mildews fastest. Combine Sunbrella with quick-dry foam for the best result.
Temperate climates with seasonal storage: cushions come inside in winter. Polyester is more acceptable here because UV exposure is limited to six months a year and storage prevents mildew during the off season.
Shaded patios: UV is not the binding constraint. Spend on stain resistance (olefin) or feel (Sunbrella) rather than fade resistance. Polyester is acceptable in deep shade.
Combined recommendation
For year round outdoor exposure in sunny climates, choose Sunbrella or equivalent solution-dyed acrylic. The 2 to 3x price premium pays back by year five.
For value-conscious buyers in any climate, choose solution-dyed olefin. Roughly 80 percent of the durability of Sunbrella at half the price.
For short-term, low-budget, or heavily shaded use, polyester is acceptable but expect to replace by year three.
For pet households, choose olefin first (best stain resistance) or Sunbrella second.
For wet climates with outdoor storage, pair Sunbrella with quick-dry reticulated foam.

Frequently asked questions
Is Sunbrella worth three times the price of polyester?+
In sunny climates with high UV (south and west US, Australia, southern Europe), yes. Sunbrella's solution-dyed acrylic holds color for 8 to 10 years versus 2 to 3 years for polyester. The cost per year of use is similar, but Sunbrella still looks like new at year 5 while polyester is faded and patchy. In shaded patios or cloudy regions, the gap closes.
What is the difference between solution-dyed and surface-dyed fabric?+
Solution-dyed fibers have the color mixed into the molten plastic before extrusion, so the color goes all the way through the fiber. Surface-dyed fibers are extruded white and then dipped in dye, which only coats the surface. Solution-dyed fabrics keep their color far longer because UV cannot strip dye that is locked inside the fiber. Sunbrella and quality olefin are solution-dyed. Most polyester is surface-dyed.
How do I clean mildew off outdoor cushions?+
For Sunbrella and acrylic: a solution of 1 cup bleach plus 0.25 cup mild soap in 4 liters of water, applied with a soft brush, left for 15 minutes, then rinsed. Sunbrella tolerates bleach. For olefin: same recipe at half bleach strength. For polyester: skip the bleach and use a 1:1 white vinegar and water mix instead, as bleach degrades polyester. Always rinse thoroughly.
Can outdoor cushions be left out in rain?+
Outdoor-grade fabric handles rain fine. The catch is the foam inside. Standard polyurethane foam soaks up water and stays wet for days, breeding mildew. Quick-dry reticulated foam (open-cell structure that drains in minutes) is the right pick for cushions that stay outside. Verify the cushion fill before assuming the whole cushion is rainproof. Many cushions ship with closed-cell foam that holds water.
Which fabric is best for pet households?+
Olefin and Sunbrella both clean up well from pet hair, mud, and accidents. Olefin is slightly easier to spot clean because it resists stains better than acrylic. Both can be hosed off. Polyester picks up pet hair more aggressively and stains easier. Skip linen-look fabrics in pet homes regardless of fiber, as the texture traps hair.
