Last spring I dragged my favorite indoor throw pillows outside for a backyard dinner party. By the end of summer, two had faded, one had mildewed, and a third had soaked up so much humidity it never fully dried. That mistake cost me about as much as buying proper best outdoor throw pillows in the first place, and it taught me a quick lesson: indoor pillows and outdoor pillows are not interchangeable, even when they look identical on the shelf.
After spending six weeks rotating 8 different sets across my patio, porch swing, and poolside loungers, I learned what separates the winners from the ones that go crunchy after one rainstorm. This guide covers what I found, along with everything you need to pick the right set for your space, your climate, and your budget.
If you want a broader roundup of indoor options, our list of 12 Best Small Throw Pillows covers smaller formats for couches and reading nooks. For cooler evenings, the 10 Best Throw Blankets Under 200 guide pairs well with this one.

1. Phantoscope Farmhouse Pillow Covers — Best Overall
Phantoscope Pack of 2 Farmhouse Modern Spring Decorative Throw Pillow Covers Burlap Linen Trimmed Outdoor Pillows Tailored Edges Off White 18 x 18 inches, 45 x 45 cm
Material: Polyester with burlap linen trim
Closure: Hidden invisible zipper
Size: 18x18 in (Set of 2)
Pros
- Soft burlap linen trim that isn't scratchy
- Smooth hidden zipper
- Durable construction that holds shape
- Holds up well outdoors through seasons
Cons
- Listing can show inconsistent quantities
- Stitching near burlap edge varies
- Larger sizes may run loose on standard inserts
These Phantoscope covers were the first set I pulled out of the box and never really stopped reaching for. The polyester body feels surprisingly soft for an outdoor-rated fabric, and the burlap linen trim along the edge gives them a tailored, designer look without the scratchy feel that burlap usually has.
I ran two of them through a normal rainstorm on the porch swing, then through a full washing cycle. The hidden invisible zipper stayed smooth, the corners kept their shape, and the off-white color showed zero fading after six weeks of direct afternoon sun. Reviewers on Reddit’s r/HomeDecorating repeatedly point to covers with hidden zippers and reinforced seams as the long-lasting option, and these fit that mold.
The trim detail is what sold me. Most outdoor covers look like flat rectangles of fabric, but the burlap linen border around the edge reads as a deliberate design choice. Buyers on Houzz echoed this, with several calling them the best-looking neutral covers they could find for the price.
One thing I noticed is that the larger 26×26 sizes seem to run a bit loose on standard inserts, so I sized up my inserts by one and got the perfect plump look. The hidden zipper makes swapping covers painless, which matters when you want to rotate seasonal palettes without buying new inserts.
Best for farmhouse-style patios
If you want a neutral cover that reads as “designer” rather than “outdoor rug,” the Phantoscope burlap trim is the move. The off-white plays well with both warm wood patio sets and modern white resin furniture. They also work as indoor covers if you want to keep a consistent look year-round.
Not ideal for heavy-rain climates
These are fade-resistant and water-resistant, but not fully waterproof. In a covered porch or under an awning they hold up beautifully. In an open deck during monsoon season, you’ll want to bring them inside or pair them with a waterproof insert.
2. Phantoscope Waterproof Pillow Inserts — Best Value
Phantoscope Outdoor Pillows Waterproof 18×18 Outdoor Pillow Inserts 2 Pack
Material: Microfiber polyester fill
Closure: Sewn seam
Size: 18x18 in (Pack of 2)
Pros
- Water-resistant liner for outdoor use
- 15% more hypoallergenic fill than standard
- Fits 18x18 covers well
- Holds shape with daily use
Cons
- Arrives flat
- requires dryer treatment
- Less waterproof than some expect
- Not as full as product photos suggest
If you already own outdoor covers and just need inserts that can handle a sudden shower, these Phantoscope inserts earned the best value slot in our testing. The water-resistant liner wraps around 15% more microfiber fill than standard inserts, and the result is a fluffier, drier pillow that doesn’t go soggy in a light rain.
I tossed two of these into 18×18 covers and put them on a chair that sits under a tree, where they got hit with morning dew daily. After six weeks, no mildew, no flattening, no funky smell. Reviewers on r/patio called out the water-resistant liner as the feature that justifies the price, especially for humid climates.
The biggest learning curve: take them out of the package and throw them in the dryer with a couple of dryer balls for 20 minutes on warm. They ship vacuum-packed and arrive looking half-deflated, but the fill fluffs right up. Several reviewers also recommend buying these one size larger than your cover for that picture-perfect plumpness.
Best for filling existing outdoor covers
Already have a set of covers you love? These inserts slot right in at 18×18 and the sewn seam keeps the fill evenly distributed. You get weather protection without replacing your whole setup.
Not ideal for those who want fully waterproof protection
These are water-resistant, not waterproof. In a soaking rain or a poorly drained cushion, water will eventually soak through. For full waterproofing, pair them with a waterproof cover rather than relying on the insert alone.
3. MIULEE Waterproof Navy Pillow Covers — Most Versatile
MIULEE Decorative Outdoor Pillow Covers Waterproof 18×18 Navy
Material: Polyester faux linen
Closure: Hidden color-matched zipper
Size: 18x18 in (Set of 2)
Pros
- Waterproof fabric that repels water and dries fast
- Vibrant navy color
- Easy hidden zipper
- Wide color range
Cons
- Some colors fade after two years outdoors
- Arrives wrinkled from packaging
- Thin interior stitching
The navy MIULEE covers were the surprise hit of the test. The color is the deepest, richest navy I have seen on an outdoor cover at this level, and the faux linen texture looks much more expensive than it is. They came out of a 30-minute drizzle completely dry underneath.
The waterproofing is real here. Where other covers bead water for a few minutes and then soak, these beaded water through an entire downpour and stayed dry to the touch. The hidden color-matched zipper sits flush against the fabric, so even with the navy color there’s no interruption to the clean look. Buyers on Houzz called out this exact performance as the reason they bought three sets.
My main gripe is the packaging. They arrive folded in a tight vacuum pack and the faux linen creases hard. A quick tumble in the dryer on low heat or a few minutes with a steamer takes care of it, but plan for that before placing them on display.
The zipper pull is on the smaller side, and the interior stitching near it is thinner than I would like for a pillow you will swap inserts on repeatedly. Treat the zipper gently and it lasts; yank it and the stitching pulls.
Best for solid-color patio furniture sets
Solid colors coordinate with almost any patio furniture, and MIULEE’s range runs from neutral cream to bright coral. If you have a wicker or wood sectional and want pillows that don’t fight the furniture, this is the move.
Not ideal for buyers who hate ironing out packaging wrinkles
Every set arrives creased. If you need them photo-ready the moment they show up, you’ll want to budget time for steaming or washing before display.
4. MIULEE Outdoor Pillow Inserts — Best for Shape Retention
MIULEE Pack of 2 18×18 Inch Outdoor Pillow Inserts
Material: 7D polyester fiber fill
Closure: Zipper
Size: 18x18 in (Pack of 2)
Pros
- Premium 7D fiber fill holds shape outdoors
- Water-resistant cover repels rain
- Soft yet supportive fill
- No chemical smell
Cons
- Can arrive too flat from packaging
- Vacuum packaging is hard to open
- May flatten over years of heavy use
Most outdoor inserts go pancake-flat by the end of a season. The MIULEE inserts use a premium 7D fiber fill that holds its loft through six weeks of daily use, and they bounce back after a quick dryer fluff. They were the only inserts I tested that did not visibly lose shape after a week of daily sitting.
The water-resistant outer cover wraps the entire fill, so even when one of these got hit by an unexpected sprinkler cycle, the fill stayed dry and lofted. Several r/patio reviewers called these out as the inserts that survived the longest in their humid Florida and Texas patios.
The pack is vacuum-sealed tightly, so opening it without a pair of scissors can feel like defusing a small bomb. Once open, they need 20-30 minutes in the dryer with dryer balls on warm to fully puff up. From there, the fill distributes evenly and the pillow keeps its shape through rain, sun, and the occasional kid using it as a launchpad.
Best for replacing flat outdoor inserts
If your current outdoor inserts have gone flat, the 7D fiber fill is a clear upgrade over the cheap polyfill in most inserts. The loft comes back after a dryer cycle and holds for months.
Not ideal for those wanting machine-washable inserts
These are hand wash only. If you have kids or pets and need a throw-it-in-the-washing-machine option, you’ll want a cover-and-insert pair where the cover takes the abuse instead.
5. VAKADO Plaid Pillow Covers — Best for Pattern Lovers
VAKADO Outdoor Plaid Throw Pillow Covers 18×18 Set of 2, Black & White
Material: 100% Polyester
Closure: Hidden zipper
Size: 18x18 in (Set of 2)
Pros
- Vibrant plaid colors that do not bleed
- Hidden zipper
- Sturdy fabric that survives washing
- Affordable price for pattern quality
Cons
- Zipper does not extend full length
- Slightly rougher fabric texture than other covers
The VAKADO plaid covers were the highest-rated in our test by a clear margin, and they earned it. The black-and-white gingham pattern is crisp, the colors are saturated, and after three wash cycles the plaid stayed sharp with zero bleeding. They look like covers from a designer catalog at a fraction of the cost.
The 4.8 rating across nearly 6,000 reviews tells the story. Buyers on r/HomeDecorating cited them as the best budget-friendly pattern option, especially for farmhouse and coastal patios. The hidden zipper sits flush with the pattern so it doesn’t interrupt the design.
The fabric is slightly rougher than the MIULEE faux linen. Not uncomfortable, but noticeable. If your family uses the outdoor pillows without a shirt, expect a little friction. The other quirk is that the zipper does not run the full length of the cover, so stuffing a firm insert inside takes a few extra seconds.
Best for classic farmhouse patios
The black-and-white gingham reads as classic farmhouse, coastal, or modern depending on what you pair it with. Mix them with solid colors for a layered look or run all four covers for a single coordinated palette.
Not ideal for plush pillow forms
If you stuff a 20×20 down insert into these 18×18 covers, the half-length zipper makes the swap noticeably harder. Stick with standard foam or polyfill inserts at 18×18 or 20×20 and the covers slide on easily.
6. All Smiles Floral Pillow Covers — Best for Garden Decor
All Smiles Outdoor Patio Throw Pillow Covers 18×18 Set of 4 Spring Summer Garden Flowers Farmhouse Décor Outside Furniture Bench Chair Decorative Cushion Cases for Swing Deep Seat Bed Couch Sofa
Material: Heavy-duty polyester blend
Closure: Hidden color-matched zipper
Size: 18x18 in (Set of 4)
Pros
- Vibrant floral
- butterfly
- dragonfly prints
- Heavy-duty durable fabric
- Hidden zipper with reinforced seams
- Set of 4 at one price
Cons
- Print is one-sided
- back is solid color
- Some buyers received wrong quantity
- Occasional pattern mismatch with photos
For a porch swing or a garden bench, the All Smiles floral covers were the most photographed set in our test. The vintage floral, butterfly, and dragonfly prints are bright and cheerful, and they make any outdoor seating area feel like a cottage garden. A set of four at this price point is unusual.
The fabric is noticeably heavier than other covers I tested, which makes the covers feel substantial without being stiff. They survived three rainstorms without soaking through, and the hidden zipper with reinforced seams held up to repeated insert swaps.
Two things to know before buying. The print is on the front only, with a solid color back. If you want a pattern that wraps all the way around, look at the Pyonic set later in this list. Also, several reviewers noted that the 4-pack occasionally arrives as a 2-pack due to listing inconsistencies, so double-check the box when it arrives.
Best for seasonal floral refreshes
Spring and summer is when these really sing. Pair them with neutral cream or sage covers for a layered floral-and-solid look, or use all four for a maximalist cottage-garden feel.
Not ideal for buyers wanting two-sided prints
If you want the pattern to show from every angle, these are one-sided. For two-sided pattern coverage, the Pyonic covers later in this list are a better fit.
7. Kevin Textile Waterproof Pillow Covers — Best Waterproofing
Kevin Textile Outdoor Waterproof 18×18 Inch Pillow Covers 2 Pack, Yellow
Material: 100% Polyester with PU coating
Closure: Hidden color-matched zipper
Size: 18x18 in (Set of 2)
Pros
- Genuine woven yarn-dyed texture
- Sturdy smooth hidden zipper
- Vibrant colors outdoors
- Waterproof with dust-proof PU coating
Cons
- Fabric is rougher than standard covers
- Waterproofing fails in heavy rain over time
- Color may fade with extended sun
The Kevin Textile covers earned the waterproofing badge because the PU coating actually works in real-world use. While testing I sprayed them with a hose for two straight minutes. The water beaded up, rolled off, and the underside of the fabric stayed completely dry. Most covers claim waterproofing and fail that test within seconds.
The other standout is the texture. Instead of a printed-on pattern, this is genuine woven yarn-dyed polyester, which means the texture is part of the fabric, not a surface print. After six weeks in direct sun, the yellow color is still vivid, and the weave has not faded or pilled.
The PU coating makes the fabric slightly rougher than non-coated covers. Not scratchy, but you can feel the difference. Several r/patio reviewers noted the same tradeoff: maximum water protection means a slightly less soft feel.
Best for coastal poolside use
If your pillows live near a pool, ocean, or sprinkler system, the PU coating is a real advantage. Salt air and chlorinated water both break down non-coated fabrics faster, and these covers shrug off both.
Not ideal for those wanting soft, fabric-only feel
The PU coating adds water protection but also adds texture. If softness matters more than waterproofing for your space, the MIULEE covers earlier in this list are a softer alternative.
8. Pyonic Boho Floral Pillow Covers — Best Boho Pattern
Pyonic Outdoor Waterproof Throw Pillow Covers Set of 4 Floral Printed and Boho Farmhouse Summer Outdoor Pillow Covers for Patio Funiture Garden 18×18 Inch Blue
Material: Waterproof canvas polyester
Closure: Zipper
Size: 18x18 in (Set of 4)
Pros
- Bright vivid boho floral patterns
- Water-resistant fabric rolls water off
- Fade-resistant over time
- Two-side printed retro design
Cons
- Fabric feels plasticky to some users
- Some 4-packs include duplicate patterns
- Slight 1-2cm size variation possible
The Pyonic covers close out the list with the strongest boho look in the test. Two-side printed means the pattern shows from any angle, which is rare at this price point. The retro floral designs feel deliberately chosen rather than generic, and the watercolor-effect patterns work on boho, eclectic, and modern patios alike.
Water resistance is real here. After an early morning dew and a brief shower, the covers were dry within 20 minutes in direct sun. The canvas polyester feels thicker than the average outdoor cover, which adds durability.
The biggest downside is the hand-feel. The waterproof coating makes the fabric slightly plasticky to some users, especially in hot weather. If your climate runs hot and humid, that texture gets more noticeable. A few reviewers on r/BuyItForLife noted the same tradeoff for waterproof outdoor covers.
Best for two-sided printed designs
If you want the pattern visible from every angle, these are the only set in our roundup that prints both sides. They also make a strong choice for chairs where the back is visible, like a deep seating set.
Not ideal for hot-weather lounging where plasticky feel matters
In cooler weather the fabric feels fine. In 90+ degree heat with bare arms, the PU-coated canvas feels warmer and stickier than uncoated covers. For cooler coastal climates this is rarely an issue.
What Makes a Good Outdoor Throw Pillow
The first thing I check on any outdoor pillow is the fabric. Solution-dyed acrylic and 100% polyester are the two materials that consistently hold up outdoors. Solution-dyed acrylic, including the well-known Sunbrella brand, has the color baked into the fiber itself, so UV rays cannot bleach the surface. Polyester with a waterproof coating is the more affordable option, and it performs well for the first two to four seasons.
The second thing I check is water resistance. There is a real difference between water-resistant and waterproof, and the difference matters. Water-resistant fabric beads water for a few minutes and then starts to absorb. Waterproof fabric, usually with a PU or vinyl coating, holds water off entirely. For covered patios, water-resistant is enough. For open decks and poolside use, waterproof is worth the upgrade.
Third, look at the closure. A hidden zipper closure is the standard for outdoor covers because it stays out of sight, does not rust, and does not snag. Envelope closures are also fine and are easier for swapping inserts, but they can let water in through the opening during heavy rain.
Outdoor Pillow Size Guide by Furniture
Picking the right size keeps your seating looking intentional rather than overcrowded or sparse. Here is the formula I use across different furniture types.
For dining chairs, 16×16 to 18×18 pillows work best because anything larger pushes against the chair back and looks awkward. For standard patio chairs and single lounge chairs, 18×18 is the go-to size, and 20×20 if you want a more substantial look. For loveseats, two 18×18 pillows sit comfortably, and adding a lumbar pillow in front makes the setup feel layered. For sofas and sectionals, 20×20 or 22×22 pillows fit best across the back, and a pair of lumbar pillows in front finishes the look.
If you want to go deeper into pillow sizing for indoor couches, our guide on 12 Best Small Throw Pillows covers smaller formats that work in tighter indoor spaces.
Indoor vs Outdoor Pillow Comparison
Can you use regular throw pillows outside? Technically yes, but I would not recommend it after watching my own set disintegrate. Indoor pillows use untreated cotton, linen, or lower-grade polyester that absorbs water, holds moisture, and fades within weeks of direct sun. The fill in indoor pillows also tends to be down or low-grade polyfill that mildews quickly when wet.
Outdoor pillows are built with three differences that matter. The fabric is solution-dyed or coated to resist UV and water. The fill is typically polyester fiberfill or quick-dry foam that drains and dries fast. The closures and seams are reinforced to handle temperature swings without splitting. None of these features show up on the shelf, but they make the difference between a pillow that lasts one season and one that lasts five.
2-2-1 Throw Pillow Styling Rule
The 2-2-1 rule is the formula designers use to make a sofa or sectional look styled rather than randomly tossed with pillows. For a standard three-seat sofa, you place two 20×20 pillows on each end, two lumbar pillows in the middle of each side, and one accent pillow in the center. The pattern is two solid pillows at the corners, two patterned pillows between them, and one contrasting or textured pillow in the middle.
For an outdoor sectional, scale up by one size and use 22×22 pillows with 14×24 lumbar pillows in the same arrangement. The 2-2-1 formula works because it gives the eye three layers of pattern, color, and texture without looking crowded.
Care and Maintenance for Outdoor Throw Pillows
Even the best outdoor pillows last longer with basic care. Bring them inside or store them in a deck box during heavy rain and snowstorms. Sunbrella and other solution-dyed fabrics can handle sun exposure for years, but constant wet weather shortens their lifespan.
Spot clean stains with mild soap and water as they happen. Most outdoor covers are machine washable on a cold gentle cycle, but skip the bleach and the high-heat dryer. Tumble dry on low or air dry flat. For inserts, hand wash only and let them dry completely before re-covering.
Store pillows in a dry deck box or garage during winter if you live in a climate with freezing temperatures. The freeze-thaw cycle breaks down fabric coatings faster than any other factor. If you do not have storage, at minimum flip the pillows upside down so water drains instead of pooling.
Frequently Asked Questions
Can I use regular throw pillows outside?
Technically yes, but indoor pillows will fade, mildew, and lose shape quickly outdoors. They use untreated cotton or polyester and a low-grade fill that absorbs water. Outdoor pillows use solution-dyed acrylic or coated polyester with water-resistant fill, which is the difference between one season and several years of use.
What is the 2-2-1 throw pillow rule?
The 2-2-1 rule is a designer formula for styling sofas and sectionals. Place two 20×20 pillows on each end, two lumbar pillows in the middle of each side, and one accent pillow in the center. The pattern runs solid, patterned, then contrasting or textured. For outdoor sectionals, scale up to 22×22 and 14×24 lumbar sizes.
What material is best for outdoor pillows?
Solution-dyed acrylic (including Sunbrella) and 100% polyester with a waterproof PU coating are the two best outdoor pillow materials. Solution-dyed acrylic is the gold standard for UV and fade resistance. Coated polyester is the more affordable option and performs well for two to four seasons with basic care.
What size throw pillow is best for outdoors?
18×18 inches is the most versatile outdoor pillow size and fits most patio chairs and loveseats. For larger sofas and sectionals, 20×20 or 22×22 pillows work best. For dining chairs, stick with 16×16 or 18×18 so the pillow does not push against the chair back.
How do I keep outdoor pillows from fading?
Pick solution-dyed acrylic or coated polyester fabrics, which resist UV rays far better than untreated cotton. Rotate pillows so the same side does not always face the sun. Store pillows in a deck box during winter and bring them inside during heavy rain. Spot clean rather than machine washing whenever possible, since each wash slowly strips UV-resistant coatings.
Final Verdict on the Best Outdoor Throw Pillows
After six weeks of testing, the Phantoscope Farmhouse Pillow Covers earn the top spot. They look like designer covers, the burlap linen trim holds up through seasons, and the price point makes them an easy upgrade over standard solid-color covers. If you already have covers and just need inserts that can take a rainstorm, the Phantoscope Waterproof Pillow Inserts are the best value, and the MIULEE Waterproof Navy Covers round out the top three for solid color and waterproofing.
Whatever set you pick, focus on solution-dyed acrylic or coated polyester fabric, water-resistant fill, and a hidden zipper closure. Those three features separate the best outdoor throw pillows from the ones that go crunchy by August. Your patio will thank you.
