Our Top Picks
The best fabric for outdoor cushions is solution-dyed acrylic, the family that includes Sunbrella and Outdura, because the color runs through the fiber and resists fading, moisture and mildew better than printed or piece-dyed polyester. If you are sewing or recovering cushions on a budget, solution-dyed polyester is a fair second choice for shaded patios, and olefin suits poolside and stain-prone spots. This guide is for the DIY and replacement-cushion reader: it covers which fabric to buy, which thread and foam to pair with it, and how much to order. It is research-based, built on manufacturer pages, product listings and published fabric guides. We did not personally use these products.
Most searches around this topic come down to three questions: which type of fabric for outdoor cushions lasts, what type of padding for seat cushions suits outdoor use, and what thread to use for sewing outdoor cushions. We answer all three, then list seven real products you can buy: five fabrics and two threads, with foam and batting in the Also Consider section.

Outdoor Cushion Fabric Types Compared
| Fabric | Fade resistance | Water and mildew | Feel | Best for | Price tier |
|---|---|---|---|---|---|
| Solution-dyed acrylic | Best, color runs through the fiber | Water-repellent, resists mildew when kept clean | Soft, cloth-like | Full sun, coastal, desert | Premium |
| Solution-dyed polyester | Good if truly solution-dyed | Less water-repellent than acrylic | Smooth to slightly stiff | Shaded patios, budgets | Mid-range |
| Olefin (polypropylene) | Good, quality varies | Absorbs very little water, dries quickly | Slightly waxy or rough | Poolside, high-traffic seating | Budget to mid-range |
| Printed or piece-dyed polyester | Weak, fades faster | Coatings wear off | Varies | Covered porches only | Budget |
| Coated polyester canvas | Moderate | Waterproof coating, can trap moisture inside | Stiff | Covers, bench pads under roofs | Budget |
The difference between “solution-dyed” and “dyed after weaving” explains most of the price spread. In solution dyeing, pigment is added to the fiber before it is spun, so the color is the fiber, not a surface. Piece-dyed or printed fabric holds color on the outside and fades from sun exposure first. When a listing says only “outdoor polyester”, assume it is the second kind unless the seller states solution-dyed.
1. Sunbrella 60 in Solid Cadet Grey: Best Overall Fabric
- Solid standard Sunbrella fabric, 60 in wide, sold by the yard
- Solution-dyed acrylic family, known for color retention
- Suits cushions, pillows and covers in full sun
- Weight and exact warranty: not listed here, check the maker
Best for: cushions that will sit in direct sun for years. Skip if: you only need a cover for a roofed porch and want to spend as little as possible.
Sunbrella is the reference point that other outdoor fabrics are compared to. Published fabric guides consistently rank solution-dyed acrylic first for fade resistance and feel, and some cite 5 to 10 years of good looks with normal care. Acrylic fibers absorb little water, so mildew has less to hold on to, but mildew still grows on dirt, so brush off debris and rinse occasionally. A 60 in width is wide enough to cut a 24 x 24 in seat top and boxing strips with limited waste.
Pros: excellent color retention; soft feel; broad color choice; trusted by cushion makers. Cons: premium cost; fabric only, so you still need thread, zipper and foam.
2. Sunbrella Cast Charcoal Upholstery Fabric: Best Textured Upholstery Look
- Indoor/outdoor upholstery fabric from the Sunbrella line
- Woven texture rather than a flat solid
- Same fiber family as pick 1
- Width and yardage: check the listing for the exact version
Best for: deep seating where you want a woven, furniture-like look. Skip if: you prefer a thin, flat fabric that is easy to sew in tight corners.
Textured upholstery weights are heavier, which gives the cushion a more tailored look but makes sewing harder. A domestic machine may struggle with several layers at the corners, so use a heavier needle and a longer stitch. If you want the Sunbrella performance and a simpler sewing job, the solid awning-weight fabric in pick 1 is easier.
Pros: upscale texture; same fiber performance; works indoors too. Cons: heavier to sew; premium cost.
3. OUTDURA 5400 Series Upholstery Fabric: Best Sunbrella Alternative
- Water-resistant outdoor upholstery fabric, per the listing
- UV fade resistant with abrasion protection, per the listing
- Marine-grade positioning
- Outdura is described in fabric guides as a solution-dyed acrylic, the closest like-for-like alternative to Sunbrella
Best for: buyers who want acrylic performance at a lower cost. Skip if: you need a specific warranty period; confirm it with the seller.
The 5400 Series is an upholstery weight, so the same sewing notes apply as for pick 2. It is a sensible way to save money without dropping to polyester. Check that the listing is for the actual Outdura fabric and the color you want, since patterns are sold by the yard and dye lots can vary between orders. Order extra to avoid running short.
Pros: acrylic fiber family; lower cost than the best-known name; upholstery weight. Cons: warranty and certifications not listed here; dye lots vary.
4. ALEKI Solution-Dyed Acrylic Marine and Awning Fabric: Best Value Acrylic
- Solution-dyed acrylic, marine and awning fabric
- 58 in wide, sold by the yard
- Lighter, flatter weave than upholstery cloth
- Black in the listing; other colors vary
Best for: first-time sewers who want an easy-to-handle acrylic. Skip if: you want a thick upholstery hand.
Awning-weight acrylic is the friendliest fabric to sew because it is thinner and flatter. It works well for seat covers, piped edges and boxing strips. Note that dark colors such as black absorb heat in direct sun, so the cushion surface can get hot; a lighter color is more comfortable.
Pros: acrylic fiber at a lower cost; wide enough for most seat panels; easy to sew. Cons: lighter feel; maker details are limited.
5. Kawsird Waterproof 600D Polyester Canvas: Best Budget Waterproof Option
- Waterproof canvas, 600D polyester
- 58 in wide in the listing; sold in a 10 yard roll
- Marketed for outdoor chair upholstery
- Solution-dyed status: not listed
Best for: covered porches, bench pads under a roof, protective covers. Skip if: the cushions sit in strong sun all day.
A coated polyester like this keeps rain out but can trap moisture if water gets in through the seams. It also fades faster than solution-dyed fabrics when the dye is not in the fiber. Use it where roof cover is reliable, or as a liner under a better top fabric.
Pros: low cost; waterproof surface; sold in large rolls. Cons: may fade; stiff hand; moisture can stay trapped.
6. Simthread UV-Resistant Bonded Polyester Thread, Tex 69: Best Thread
- 100% polyester bonded thread
- Tex 69 (12 weight), described as heavy duty and UV resistant
- For hand or machine sewing
- Many colors; match to your fabric
Best for: seams that carry load and face the sun. Skip if: your machine cannot handle a heavy thread; check your needle and tension.
Thread is the part that fails first on outdoor cushions. Cotton thread rots in a season. Plain polyester can degrade under UV. A bonded polyester thread around Tex 69 to 70 is the usual choice for upholstery and marine sewing because the bonding resists fraying and the polyester resists UV and mildew. Pair it with a size 18 or 100/16 needle, a longer stitch of about 3 to 4 mm and a slightly looser top tension.
Pros: UV-resistant; strong; hand or machine use. Cons: thicker thread needs a heavier needle; some machines need tension tuning.
7. Selric UV-Resistant Polyester Thread, #69 T70: Best Thread Alternative
- High strength polyester thread, #69 T70, 210D/3
- 1,500 yard spools in the listing
- Offered in a large color range
- Suited to upholstery and outdoor sewing
Best for: bigger projects like a whole patio set. Skip if: you only have one small cushion to sew.
A 1,500 yard spool goes far. A set of four seat cushions with boxing, zippers and welting can use several hundred yards. If you plan a set, buy one large spool in a color that blends with your fabric rather than several small spools.
Pros: large spool; strong; many colors. Cons: overkill for one cushion.
Also Consider
- Coats Outdoor Living Thread: A widely stocked outdoor sewing thread in 200 yard spools, handy for small repairs.
- Foamma outdoor foam, 4 x 24 x 24 in: A replacement seat foam made from high-density polyurethane for patio furniture.
- SUNROX DryFast foam, 3 x 24 x 72 in: An all-weather quick-drying foam sheet to cut for benches and long cushions.
- AK Trading Co. bonded Dacron batting: Polyester batting used to wrap foam, smooth edges and add a softer loft.
How to Re-Cover or Sew an Outdoor Cushion
- Measure the foam, not the old cover. Old covers shrink and stretch. Measure the foam width, depth and thickness in inches.
- Calculate fabric. For a 24 x 24 x 4 in seat cushion, you need two panels of about 25 x 25 in and four boxing strips of about 5 x 25 in, which is about 1.25 yards of 58 to 60 in fabric once seam allowances are included. A zipper opening on the back edge adds a little more.
- Cut the foam slightly large. Many makers cut the foam 1/2 in larger than the cover in width and depth so the cover fills out firmly.
- Wrap in batting. A single layer of polyester batting rounds edges and prevents the foam corners from showing through.
- Sew with bonded thread. Use Tex 69 to 70 UV-resistant polyester, a heavy needle and a longer stitch. Reinforce corners and zipper ends.
- Include a zipper. Choose a polyester zipper and keep the opening on the back or bottom so you can remove the cover for washing.
What Type of Padding for Seat Cushions Works Outdoors?
| Padding | Typical use | Outdoor suitability | Watch for |
|---|---|---|---|
| Quick-dry open-cell foam | Seats exposed to rain | Best for wet climates | Costs more per inch |
| High-density polyurethane foam, about 2.2 density / 50 ILD | Seat and back cushions under cover | Good when kept dry | Holds water if soaked |
| Polyester fiberfill | Pillows and back cushions | Fair; dries slowly | Flattens and clumps |
| Polyester batting | Wrap over foam | Good as a top layer | Not structural |
The foam type matters as much as the fabric. A great cover over wet-holding foam still turns mildewy from the inside. In rainy regions choose a quick-dry foam; in covered patios a standard high-density foam is fine. For seat cushions, 3 to 5 inches thick and 50 ILD or firmer is common for outdoor seating, while back cushions can be softer.
How We Chose
This guide is research-based. We compared manufacturer and seller listings with published outdoor fabric guides from furniture and fabric retailers, and we summarized points where they agree, such as acrylic outperforming polyester for fade resistance. We did not personally use these products and we do not claim measurements. Details such as fabric weight, warranty and dye method were often not published in the listings, so they are marked “not listed”. We kept no more than two products per brand and mixed fabrics and thread so that you can build a full project list.
Buying Guide
Choose fiber by sun exposure
Full sun for more than six hours a day, coastal air or desert heat calls for solution-dyed acrylic. Part shade and moderate weather allow solution-dyed polyester or olefin. Covered porches are fine with coated polyester. A fabric that is right for a covered porch is often wrong for an open deck.
Check the weave and weight
Awning and marine weights are thinner and sew easily. Upholstery weights look richer but are harder to sew. If you are new to sewing, start with the lighter weight.
Look for solution-dyed on the label
If the listing does not say solution-dyed, treat the fabric as printed or piece-dyed. Price alone is not a guide, so read the description.
Plan the yardage
Add 10 to 15 percent for pattern matching, mistakes and dye-lot differences. For a set of four 24 x 24 in seat cushions, plan for roughly 5 to 6 yards of 58 to 60 in fabric. Order all the fabric at once so colors match.
Match thread, zipper and piping
Use UV-resistant bonded polyester thread and polyester zippers. Cotton piping cord rots; use polypropylene or synthetic cord instead.
Common Mistakes to Avoid
- Buying decorative indoor fabric and expecting it to survive a summer outdoors.
- Using cotton or standard polyester thread that fails before the fabric does.
- Pairing a premium fabric with sponge-like foam that holds water.
- Ordering the exact yardage and running short when a seam goes wrong.
- Washing with bleach or high heat; follow the fabric maker’s care guide.
Frequently Asked Questions
What is the best fabric for outdoor cushions?
Solution-dyed acrylic, such as Sunbrella or Outdura, is the best all-round choice for fade resistance and durability. Solution-dyed polyester and olefin are good lower-cost alternatives for shaded or covered spaces.
What is the best type of fabric for cushions in full sun?
Solution-dyed acrylic is generally recommended, because its color runs through the fiber and holds up to prolonged UV exposure better than most polyester.
Is polyester or acrylic better for outdoor cushions?
Acrylic is better for fade resistance and mildew resistance, while polyester is cheaper and acceptable for shaded areas. Only solution-dyed polyester should be used outdoors; printed polyester fades quickly.
What is the best thread for sewing outdoor cushions?
Use UV-resistant bonded polyester thread, typically around Tex 69 to 70. It resists sun and mildew and is stronger than cotton or all-purpose thread.
What is the best type of padding for seat cushions?
For outdoor use, a high-density or quick-dry foam of 3 to 5 inches wrapped in polyester batting is common. Choose quick-dry foam where rain is frequent.
How much fabric do I need for a 24 x 24 inch seat cushion?
About 1.25 to 1.5 yards of 58 to 60 inch fabric, depending on thickness, welting and zipper placement. Add extra if the fabric has a directional pattern.
Can I use regular indoor upholstery fabric?
Not for long. Indoor fabrics usually lack UV and moisture resistance and can fade or mildew within a season. Choose fabric marked for outdoor or marine use.
Which One Should You Buy?
If the cushions sit in sun, buy Sunbrella solid fabric and bonded polyester thread, and cut foam to size. If you want the same fiber family for less, look at the OUTDURA upholstery fabric or ALEKI awning acrylic. If the seating is under a roof, the Kawsird canvas can work. For thread, Simthread suits a single project and Selric suits a larger set.
The most useful rule is to spend where failure shows first: fabric fiber, then thread, then foam. A cheap cover over good foam can be replaced, but a good cover sewn with weak thread fails at the seams.
