The best place to buy outdoor patio cushions depends on one question: does your furniture take a standard size? If it does, a ready-made set such as the Summsun bench cushion or the Aegisun rocking chair cushion is the quickest fix, and if it does not, buying cut-to-size foam from FoammaUSA and pairing it with a new cover is the cheapest way to get an exact fit. This guide covers where to shop, how to choose between ready-made, custom-made and do-it-yourself routes, and which specific bench, rocking chair, foam and fabric-protector products are worth a look.

Where to Buy Outdoor Cushions: Four Routes Compared
You can buy outdoor cushions from four kinds of source, and each suits a different problem. Knowing the route before you shop saves more money than any single product choice.
Ready-Made Online Stores for Standard Sizes
The best place to buy outdoor cushions in standard sizes is a large online store that sells many sizes of the same style, because you can compare thickness, cover fabric and tie positions side by side. Ready-made is the right route for benches (commonly 36, 42, 48 and 60 inches long), rocking chairs, standard dining seats and swing seats. It is also the best place for inexpensive outdoor cushions, since mass-produced sizes carry lower prices than made-to-order work.
Specialty Cushion Makers for Custom Sizes
The best place for custom outdoor cushions is a specialty maker who lets you enter your own measurements and choose an outdoor-rated fabric. Expect to pick fabric, foam thickness, edge style (box edge or knife edge), ties or no ties, and sometimes piping. Lead times are longer than for ready-made cushions, and returns are usually limited because the item is made for you, so measure twice.
Local Upholstery and Fabric Shops
The best place to have outdoor cushions made if you want to see the fabric first is a local upholstery or awning shop. You can handle samples, ask for a zipper in a specific position, and bring an old cushion as a template. The trade-off is that labor can cost more than buying a cover from a specialty maker, so ask for a written quote that separates foam, fabric and labor.
Do-It-Yourself: Foam Plus Cover
The cheapest way to replace flat, tired cushions is to keep the covers if they are sound and replace only the foam, or to buy a cut-to-size foam block and a ready-made or sewn cover. FoammaUSA sells custom cut foam, and SUNROX sells a large all-weather foam block that you can cut yourself. This route rewards patience: it takes an hour or two but is the only way to get unusual sizes such as window seats, round daybeds and built-in banquettes without paying for custom fabrication.
| Route | Best for | Speed | Fit control | Watch for |
|---|---|---|---|---|
| Ready-made online | Standard benches, rockers, dining seats | Fastest | Low (nominal sizes) | Listing sizes often differ slightly from the real cushion |
| Specialty custom maker | Non-standard frames, specific fabric | Slowest | High | Limited returns on made-to-order items |
| Local upholstery shop | Seeing fabric, repairs, complex shapes | Medium | High | Labor can add to the total; get a written quote |
| DIY foam plus cover | Window seats, daybeds, budget refresh | Medium | High | Cutting foam cleanly takes a sharp blade |
1. Summsun Outdoor Bench Cushion Pad: Best Overall Ready-Made Pick
- Size: 48 x 18 x 3 inches in black (other options not listed here)
- High-resilience foam with a removable cover and hidden zipper
- Tie strap included for securing to the bench
- Described by the maker as water resistant and suited to patio, garden, swing, porch and settee use
Best for: standard garden benches and porch swings where you want a clean, simple look. Skip if: your bench seat is hard hardwood and you sit for long stretches, because 3 inches of foam is on the slim side.
The detail that matters most on a bench cushion is the cover, not the foam. A removable cover with a hidden zipper means you can wash or replace the fabric while keeping the foam, which stretches the life of the cushion. The tie strap matters for porch swings, where the cushion slides forward every time someone sits and leans back.
Measure your bench before you click. A 48 inch cushion on a 46 inch bench will bunch against the arms, and one that overhangs the seat edge will droop. Measure the usable seat between the arms, not the overall outside width.
Pros:
- Removable cover with hidden zipper
- Tie strap helps on swings
- Neutral color suits most frames
- Common 48 inch size
Cons:
- Only 3 inches thick
- Water resistant is not the same as waterproof, so bring it in during storms
2. IPYNBAP Outdoor Bench Cushion, 48 x 18 x 5 Inch: Best Thick Bench Seat
- Size: 48 x 18 x 5 inches in navy blue
- Listing calls it water resistant and fade resistant, for indoor or outdoor use
- Designed for patio benches and porch swings
- Fill material and cover fiber: not listed in the title
Best for: hard slatted benches where comfort is the priority. Skip if: your bench has a shallow seat well or armrests that leave little space above the seat, since a 5 inch cushion can ride higher than the arms.
Thickness is the one spec that changes how a bench feels. Going from 3 to 5 inches roughly adds the cushioning of a dining chair pad. The compromise is that thicker foam takes longer to dry if rain gets in, and it is harder to keep in place without ties. Check the listing for tie positions before buying.
If you are replacing a bench cushion and want to keep costs low, this is the kind of ready-made cushion to consider first. Compare it against the Summsun above: same footprint, different thickness, so you can choose based on how long people actually sit there.
Pros:
- 5 inch thickness for hard seats
- Common bench footprint
- Fade-resistant claim from the seller
Cons:
- May sit higher than armrests
- Fiber and foam type not listed
3. Aegisun High Back Rocking Chair Cushion, 44 x 23 x 4 Inch: Best for Rocking Chairs
- Size: 44 x 23 x 4 inches, navy blue
- High back memory foam design for Adirondack and rocker styles
- Includes ties
- Waterproof and fade-resistant per the listing; treat that as a seller claim, not a rating
Best for: classic porch rockers with a tall slatted back. Skip if: your rocker has a short back or a curved seat that does not match a one-piece pad.
A one-piece high back cushion is the simplest way to cover both seat and back of a rocking chair. The ties are not decoration: a rocker moves, and without ties the cushion creeps forward until the seat is bare. Tie it at the back posts and again at the front seat rail if the listing includes enough strap.
Before ordering, measure seat width at the front, seat depth, and the distance from the seat to the top of the back. Rockers vary a lot, and a cushion that is a few inches too narrow leaves slats exposed, which defeats the purpose.
Pros:
- One piece covers seat and back
- Memory foam for a softer feel
- Ties help stop sliding
Cons:
- Memory foam can be warm in full sun
- Fixed shape may not suit every rocker
4. WEOAVRY Rocking Chair Cushions, Set of 2: Best Seat and Back Pair
- Seat and back cushion set for porch gliders and rockers
- Ties included
- Sold as a set of 2; exact dimensions and foam thickness: not listed in the title
- Marketed for both indoor and outdoor use
Best for: gliders and rockers with a distinct seat and a separate back rail, where a one-piece cushion does not lie flat. Skip if: you need exact sizes confirmed before purchase and the listing does not show them for your chair.
Two-piece sets let the seat stay flat while the back follows the slats, which usually feels better than a bent one-piece cushion. They are also easier to replace if only one part wears out, though most sellers do not sell the parts separately. Check the product page for dimensions and compare them to your chair before ordering.
Pros:
- Separate seat and back pieces
- Ties on both pieces
- Works for gliders as well as rockers
Cons:
- Dimensions need verification on the product page
- Two pieces means two sets of ties to manage
5. FoammaUSA Custom Cut Upholstery Foam: Best Custom Foam Route
- Cut to your own shape and size
- High or medium density polyurethane foam options
- Suited to chairs, benches, boat and car seats, poker tables and furniture cushions
- Made in the USA per the listing
Best for: window seats, banquettes, boat seats and any cushion that has no standard size. Skip if: you need outdoor-rated, quick-drying foam for an uncovered, rain-exposed seat, since this listing is general upholstery foam rather than a drain-through outdoor foam.
The reason this route works is that foam and cover are separate. A cover maker can sew an outdoor-rated cover to your measurements, while a foam supplier cuts the insert. Ask for foam about half an inch to an inch larger than the cover in each direction, because that makes the finished cushion look plump rather than flat.
For high-traffic seats, high density foam holds its shape longer than medium. For rarely used decorative seats, medium density saves money. The listing does not state firmness numbers, so confirm the density options on the product page before ordering.
Pros:
- Fits any shape
- Choice of density
- Starting price is low
Cons:
- You need to supply or sew a cover
- Not specifically a quick-dry outdoor foam
6. SUNROX DryFast Foam, 4 x 24 x 72 Inch: Best for Humid Yards
- Size: 4 x 24 x 72 inches
- Marketed as all-weather outdoor cushion foam that is durable and low maintenance
- Intended for outdoor seat cushions and patio furniture chair cushions
- Density rating: not listed
Best for: chaises, long benches and daybeds in damp climates, and as a replacement for foam that stays wet. Skip if: you only need one small seat pad, since a 72 inch slab is more than you need.
Drain-through foam is designed so water does not stay trapped, which reduces the musty smell that develops inside standard foam. If your cushions regularly sit through rain and you have had trouble with mildew, replacing the core with a quick-dry foam is often a better fix than buying another set of covers.
A 24 by 72 inch slab suits a chaise lounge cushion, and you can cut it with a long serrated knife or an electric carving knife for two benches. Mark your lines with a marker, cut slowly, and keep the blade straight.
Pros:
- All-weather design
- Large size suits chaises and long benches
- You choose your own cover
Cons:
- Premium price tier
- You must cut and cover it yourself
7. 303 Fabric Guard Water Repellent, 16 oz: Best Protectant
- Restores water and stain resistance on outdoor fabric, canvas, cushions and upholstery per the maker
- Size: 16 ounce spray bottle (larger sizes also exist)
- Coverage per bottle: not listed here; check the label
Best for: cushions whose fabric still looks fine but no longer beads water. Skip if: the fabric is torn, thin or already mildewed; protectant does not fix damaged cushions.
The best outdoor protectant for cushions is one that matches your fabric and is applied correctly: clean the cushions first, let them dry fully, then spray lightly and evenly in a ventilated area following the label. Applying protectant over dirt locks the dirt in. Reapply when water stops beading, usually after a season of heavy sun and washing.
Check the label for fabric compatibility. Some treatments can darken or stain certain materials, so try a hidden corner first, and check what the maker says about safe drying time before people sit on the cushions.
Pros:
- Extends the life of existing covers
- Inexpensive compared with new cushions
- Made for outdoor fabrics
Cons:
- Needs clean, dry fabric and reapplication
- Does not make fabric waterproof
Also Consider
- Scotchgard Outdoor Water and Sun Shield Fabric Spray, 10.5 oz: A lower-cost protectant in a smaller can that works for a single bench or a few chair pads. Check the label for fabric compatibility.
- Sunbrella Restore Fabric Protector, 32 oz: Listed as a non-PFAS water repellent spray, a good choice if you own Sunbrella-branded cushions or want to avoid PFAS products.
- Codi Rocking Chair Cushions, 1 pack: A seat and back set with 3 inch foam, non-slip backing and a standard rocker fit per the listing; a close alternative to the WEOAVRY set.
- Outdoor Bench Cushion with ties, 48 x 16 inch (Natural): A narrower bench cushion for shallower seats where 18 inches is too deep.
Cushions for Specific Spots: Quick Answers
Where is the best place to buy outdoor bench cushions?
The best place is a ready-made seller with many bench sizes, since bench cushions are among the most standardized outdoor cushions. Measure the seat between the arms, compare thickness (3 versus 5 inches), and confirm there are ties for swings.
What are the best outdoor rocking chair cushions?
Choose a one-piece high back cushion such as the Aegisun for tall slat backs, or a two-piece set such as the WEOAVRY or Codi for rockers and gliders where seat and back sit at different angles. Ties are essential because rockers move.
Where can I buy window seat cushions?
Window seats rarely match standard sizes, so cut-to-size foam plus a custom cover is the usual route. FoammaUSA custom cut foam suits this job indoors; use an outdoor-rated foam and fabric if the window seat is on an enclosed porch that gets damp.
What about floor cushions and classroom cushions?
For floor cushions and classroom seating, buy from a seller of floor pillows or square cushions in a tough, wipe-clean cover. Look for removable washable covers, a firm fill and non-slip bottoms. These are different products from patio chair pads, which are thinner and have ties.
Where can I buy chaise lounge cushions?
Chaise cushions are commonly sold at about 72 inches long by around 21 to 24 inches wide, but sizes vary. Measure your frame, and choose a cushion with an adjustable back if your chaise reclines. A 72 inch slab of foam like SUNROX is a good base if you plan to make your own.
How We Chose
This guide is research-based. We did not personally use these products. We read manufacturer and seller listings, compared sizes and materials, looked at what independent buying guides and fabric makers publish about outdoor foam and fabric care, and then matched products to the shopping routes above. We only name products found in the store’s current product catalog, we avoid quoting prices (only tier words), and where the listing does not state a spec, such as foam density, we say it is not listed. Check each product page for the latest specs before buying.
Buying Guide
Measure Before You Choose a Route
Measure the seat area at the widest and narrowest points, the depth front to back, and the height of the back if you need a back cushion. Write the numbers down. For benches, measure between the arms, not the overall bench. For chairs with curved seats, trace the seat on cardboard and use that as a template for custom orders.
Thickness and Foam
Three-inch cushions suit chairs with a built-in sling or contoured seat, four inches is the standard for dining and lounge seats, and five inches or more suits hard benches and chaises. For foam, high density holds shape longer than medium. Outdoor drain-through foam, such as SUNROX DryFast, is designed to dry faster than standard polyurethane, which matters most in rainy or humid climates.
Fabric and Cover
Solution-dyed acrylic and polyester are common outdoor choices, and polyester is usually less expensive. Look for removable covers with zippers so you can launder them. Fade resistance is mainly about the dye method and UV treatment. Marketing terms such as water resistant are not guarantees, so plan to store cushions or cover them during heavy rain.
Ties, Backing and Fit
For benches and swings, ties and non-slip bottoms are often more important than thickness. A cushion that slides forward every time someone sits down will feel uncomfortable no matter how thick it is. For rockers, ties at the back are essential.
Custom Versus Ready-Made
Choose custom when the frame is non-standard, when you need a specific color to match other furniture, or when you want to specify foam density and edge style. Choose ready-made when your furniture takes a common size and you want the cushions soon. Choose a DIY foam swap when the covers are in good shape but the foam has flattened.
Common Mistakes to Avoid
- Ordering by nominal size without measuring the seat.
- Assuming water resistant means waterproof and leaving cushions out in storms.
- Applying protectant over dirty or mildewed fabric.
- Buying thick foam for a seat with armrests that leave no headroom.
- Skipping ties on swings and rockers.
- Ordering custom covers without confirming whether returns are accepted.
Frequently Asked Questions
What is the best place to buy outdoor patio cushions?
For standard sizes, a large online store with many sizes is best; for custom sizes, a specialty cushion maker is best. Which one is right depends on whether your furniture matches a common size, so measure first.
What is the best place for inexpensive outdoor cushions?
Ready-made cushions in common sizes are generally the least expensive, and replacing only the foam in existing covers is cheaper still. Avoid paying for features you do not need such as extra thickness or piping.
Where can I have outdoor cushions made?
Specialty custom cushion makers and local upholstery or awning shops make outdoor cushions to measure. Ask for outdoor-rated fabric, a removable cover, a written quote and the return policy before paying.
What is the best foam for outdoor cushions?
Quick-dry, open-structure outdoor foam is the best choice for wet climates, while high density polyurethane suits covered porches. Confirm the density and thickness on the product page, because listings often leave this out.
What is the best outdoor protectant for cushions?
A water repellent made for outdoor fabrics, such as 303 Fabric Guard, Scotchgard Outdoor Water and Sun Shield or Sunbrella Restore, is the usual choice. Clean and dry the fabric first, follow the label, and try a hidden corner for color changes.
How do I measure for replacement foam?
Measure the cover or the old foam at its widest points and add about half an inch to an inch to each dimension so the foam fills the cover. Measure thickness when the old foam is not compressed, or choose a standard thickness such as 3, 4 or 5 inches.
Where is the best place to sell cushions?
If you sell used or handmade cushions, general marketplaces and local classifieds reach the most buyers; add clear photos, exact dimensions and the cover material. This is selling advice rather than a product recommendation, so check each platform’s rules.
Which One Should You Buy?
If you have a standard bench, start with the Summsun for a slimmer look or the IPYNBAP for a thicker seat. If you have a rocker, pick the Aegisun for a one-piece high back or the WEOAVRY set for a seat and back pair. If your furniture has an unusual shape, buy FoammaUSA custom cut foam and have a cover made or sewn. If your cushions live in a damp climate, choose SUNROX DryFast foam. If the covers are sound but no longer shed water, a bottle of 303 Fabric Guard costs far less than replacing the cushions.
