Which Sunbrella patio furniture cushions suit each seat?
Unimatta is the best match here for a group of standard square chairs, while RSH DECOR fits a more specific U-shape wicker seat. Supflourishia and Supdurplus also offer 19-inch square cushions, with different cover-care instructions.
These picks are arranged by score, but fit should decide your choice. Measure the seat and check the cushion shape, thickness and set size before ordering.
Our score weighs specs and features against what you’re shopping for: replacement cushions made with Sunbrella outdoor fabrics. We distinguish complete cushions from cover-only sets so you can compare what you actually need.

Best Sunbrella cushions for chairs and wicker seats
Choose a cushion that matches both the seat footprint and its shape. For a chaise, compare patio chaise lounge cushions sized for its longer seat.
A square cushion may not sit properly on a rounded or U-shape wicker frame.
IASEAHK Patio Chair Cushions: Best for value in a 4-pack
- Set of 4
- 19 x 19 x 3 in
- 30D foam
- Removable machine-washable covers
This 4-pack offers a familiar square size, foam fill, ties and removable machine-washable covers. Its fabric is polyester, not Sunbrella, so it suits shoppers prioritizing a washable replacement set over Sunbrella branding.
Pros
- 4 cushions in the set
- Removable machine-washable covers
- Two adjustable straps and a handle
Cons
- Not made with Sunbrella fabric
- 3 in thick
IASEAHK is a practical 4-pack for replacing several square chair cushions at once. Each is 19 x 19 x 3 inches, with 30D foam, two adjustable straps and a handle.
Its polyester Oxford fabric is water resistant, UV resistant and fade resistant. The cover is removable and machine washable, but this set is not made with Sunbrella fabric, so choose it only if the washable replacement matters more than the named fabric.
Before buying, compare the chair seat dimensions with the cushion's 19-inch square footprint. The 3-inch thickness may also feel different from a deeper original cushion.
RSH DECOR: Best for thick U-shape wicker seats
- Set of 2
- 22 x 22 in U-shape seats
- 6 in thick
- 100% solution-dyed acrylic Sunbrella fabric
These tufted U-shape cushions pair 6-inch thickness with Sunbrella acrylic covers. Measure the inner edges of the wicker seats and check their shape before choosing this set.
Pros
- Sunbrella acrylic fabric
- Thick 6 in fill
- Reversible cushions
Cons
- U-shape limits fit
- Spot clean and air dry
RSH DECOR is the specific pick for U-shape wicker seats that need a deeper cushion. The set includes 2 tufted cushions, each measuring 22 x 22 inches and 6 inches thick.
Its cover uses 100% solution-dyed acrylic Sunbrella fabric. The cushions are reversible and filled with hospitality-grade fiberfill, and RSH DECOR recommends spot cleaning with mild soap and water, then air drying.
Measure the inner edges of your wicker seats from side to side and front to back. This shape and size won't suit every wicker chair, so check the seat outline before choosing it.
Unimatta Sunbrella Square Corner Seat Cushions: Best for standard square patio chairs
- Set of 4
- 19 x 19 x 3 in
- Reversible
- Sunbrella acrylic with ties
A set of 4 square cushions fits shoppers replacing several standard patio chair pads at once. The covers are Sunbrella acrylic, and the cushions can be flipped for use on either side.
Pros
- Sunbrella acrylic fabric
- Reversible design
- Spot clean with soap and water
Cons
- Measure for a 19 x 19 in seat
- Only 3 in thick
Unimatta is the strongest fit for a set of 4 standard square patio chairs that measure close to 19 x 19 inches. Each cushion is 3 inches thick, reversible and made with Sunbrella acrylic fabric.
The ties help hold the cushions in place, and the covers can be spot cleaned with soap and water. Unimatta also provides a 1-year limited service agreement for manufacturing defects and a 5-year limited service agreement for certain Sunbrella fabric issues.
Choose it when you want a matched set for several chairs. Measure each seat, since “universal” fit doesn't mean every patio chair has the same usable space.
Aoxun Replacement Cushions for Outdoor Furniture: Best for a six-seat conversation set
- 14-piece set
- Seat and back cushions
- 4 in seat cushion thickness
- Polyester fabric
This large replacement set includes seat, back and corner cushions for a 6-seat conversation set. It uses polyester fabric rather than Sunbrella, so compare the full size layout before choosing it.
Pros
- Includes 14 cushions
- Designed for a 6-seat set
- Removable machine-washable covers
Cons
- Not made with Sunbrella fabric
- Large set requires careful measuring
Aoxun's 14-piece set is sized for a 6-seat patio conversation set, with 6 seat cushions, 6 back cushions and 2 corner cushions. The seat cushions measure 25.6 x 25.6 inches and are 4 inches thick.
The polyester fabric is described as splash-proof and fade resistant, and the covers are machine washable. This is not a Sunbrella set, but it may suit a buyer replacing a whole sectional arrangement rather than individual chair pads.
For whole-set protection, compare outdoor sectional covers.
Check the corner and back cushion sizes against your furniture layout. The set arrives vacuum packed and may need 48 to 72 hours to expand.
Summsun Outdoor Chair Cushions Set: Best for deep-seat comfort
- 24 x 24 in seat cushions
- 4 in thick seat foam
- Attached ties and non-slip bottoms
- Removable covers
The 24-inch seat cushions and separate back cushions suit deep patio seating. Their faux linen polyester fabric is water repellent, but it is not Sunbrella.
Pros
- Thick 4 in seat foam
- Two sets of attached ties
- Removable covers
Cons
- Not made with Sunbrella fabric
- Measure the seat and back separately
Summsun pairs 24-inch deep seat cushions with separate back cushions, making it a match for chairs or sofas designed for larger pads. The seats are 4 inches thick, with high-density foam, while the backs use shredded foam and PP cotton.
The faux linen polyester fabric has a water-repellent coating and a water-resistant inner membrane. Summsun recommends bringing the cushions indoors during heavy rain or storms, and the covers can be removed for washing.
This is not made with Sunbrella fabric, so consider it if the dimensions and deep-seat format matter more than the cover brand. Measure both the seat and back before choosing the set.
Supflourishia 19 x 19 Inch Sunbrella Outdoor: Best for washable Sunbrella covers
- Set of 4
- 19 x 19 x 3 in
- Sunbrella acrylic fabric
- Removable machine-washable covers
This 4-pack combines a common square-chair size with removable machine-washable Sunbrella covers and two ties. The stated 3-inch thickness makes it a closer match for slimmer seat frames.
Pros
- Sunbrella acrylic fabric
- Removable machine-washable covers
- Two ties per cushion
Cons
- Only 3 in thick
- Allow up to 48 hours to expand
Supflourishia suits buyers who want Sunbrella fabric and machine-washable removable covers in a familiar 19-inch square format. The set includes 4 cushions, each 19 x 19 x 3 inches, with two ties to limit shifting.
The cover is acrylic, and the maker describes it as Sunbrella fabric. Cushions arrive vacuum packed and may take up to 48 hours to expand; the brand also provides a 1-year limited service agreement for manufacturing defects and a 5-year limited service agreement for certain fabric issues.
Choose this set when being able to remove and wash the covers is a priority. Confirm the thickness and seat dimensions before replacing a deeper or unusually shaped cushion.
Supdurplus Outdoor Sunbrella Square Corner Seat Cushion: Best for spot-clean care
- Set of 4
- 19 x 19 x 3 in
- Sunbrella acrylic fabric
- Spot clean with soap and water
These square-corner cushions offer Sunbrella acrylic fabric in a set of 4. Their care guidance calls for spot cleaning, which suits shoppers who don't need machine-washable covers.
Pros
- Sunbrella acrylic fabric
- 4 cushions per set
- Spot clean with soap and water
Cons
- Only 3 in thick
- Compressed for shipping; allow 48 hours to expand
Supdurplus offers another 4-pack of 19 x 19 x 3 inch square cushions made with Sunbrella acrylic. The care guidance is simple: spot clean with soap and water.
The cushions are compressed for shipping and need about 48 hours to expand. Supdurplus provides a 1-year limited service agreement for manufacturing defects and a 5-year limited service agreement for certain Sunbrella fabric issues.
This is a good fit when a spot-clean cover is acceptable and the square dimensions match your chairs. If you want a removable cover for machine washing, compare the Supflourishia option instead.
Snubbull 14 Pcs Outdoor Cushion Slipcovers Outdoor: Best for replacing covers only
- 14 cover pieces
- Polyester fabric
- Zippers
- Covers only, no inserts
These covers let you keep existing inserts while refreshing a 7-piece patio set. They are polyester, not Sunbrella, and don't include cushion inserts.
Pros
- Keeps existing cushion inserts in use
- 14 covers for seats and backs
- Zippers for inserting cushions
Cons
- No inserts included
- Not made with Sunbrella fabric
Snubbull sells 14 replacement covers for a patio conversation set, including seat and backrest covers in several sizes. The covers use polyester fabric, zippers and a non-slip design on the seat covers.
This set contains covers only, with no cushion inserts, and it isn't made with Sunbrella fabric. It can work when your existing foam is still usable and you want to replace the outer fabric.
Measure every insert, including the back cushions, before ordering. A multi-piece cover set only helps if its dimensions match the cushions you already own.
Artfurniz 6" Thicker Outdoor Chair Cushion: Best for 6-inch seat cushions
- Two seats and two backs
- 24 x 24 x 6 in
- Olefin fabric
- Removable covers
This 2-seat and 2-back set provides 6-inch seat cushions for deep patio furniture. The cover is olefin, not Sunbrella, so consider it when thickness matters more than matching the requested fabric.
Pros
- 6 in seat thickness
- Removable covers
- Seat and back cushions included
Cons
- Not made with Sunbrella fabric
- Two seat cushions per set
Artfurniz includes 2 seat cushions and 2 back cushions for a deeper patio chair or small sofa. Its seat cushions measure 24 x 24 x 6 inches and use 28D high-density sponge fill, while the covers are olefin.
The removable covers have hidden zippers, and the maker describes the fabric as water repellent. This set is not Sunbrella, but its 6-inch seat thickness may suit furniture that needs a substantial cushion.
Check that the set's 2 seat and 2 back pieces match your layout. It won't replace a full sectional set or a group of four separate chair cushions.
How do you measure for replacement Sunbrella cushions?
Measure the usable seat width and depth, then compare them with the cushion's finished dimensions. For shaped wicker furniture, trace or measure the inside seat edges so a square cushion doesn't overhang or leave gaps.
Check thickness as well as width and depth. Replacing a 6-inch cushion with a 3-inch pad can change how the chair feels and how high you sit.
Count the pieces you need before selecting a set. A 4-pack of seat pads won't replace the backs and corners of a sectional.
For more options by cushion shape and project size, compare our Best Replacement Cushions guide. If you're weighing custom sizes and materials, our guide explains why patio furniture cushions are so expensive.
Is Sunbrella fabric the right choice for outdoor cushions?
Sunbrella acrylic is worth considering when you want a named outdoor fabric and care features suited to patio use. The products here vary in cushion fill, shape and maintenance, so fabric alone doesn't determine whether a set fits your needs.
Some options in this roundup use polyester or olefin instead of Sunbrella. Those can still be relevant for a replacement project, but check the material carefully if Sunbrella is a must-have.
Consider storage and care, too. Some cushions call for spot cleaning, while others have removable covers that can be machine washed; follow the instructions for the specific set.
Which cushions work for rocking chairs or recliners?
Rocking chairs and recliners often need cushions shaped for their seat, back or moving parts. For taller chair backs, compare high-back patio chair cushions.
Standard 19-inch square chair pads may not provide the coverage or fit you need.
Use our guides to best outdoor rocking chair cushions and best outdoor recliner chair cushions to compare options made for those seating styles. Measure your furniture before choosing a replacement.
Which Sunbrella patio furniture cushions should you choose?
Choose Unimatta for a set of 4 standard 19-inch square chairs, RSH DECOR for 6-inch U-shape wicker seats, and Supflourishia if you want removable machine-washable Sunbrella covers. For large sectionals or cover-only refreshes, check the piece count and material closely, since several alternatives here are not Sunbrella.

Frequently asked questions
Are Sunbrella patio cushions waterproof?
Sunbrella fabrics are designed for outdoor use and resist water, but cushion seams and inserts can still take on moisture. RSH DECOR recommends covering or storing its cushions during inclement weather.
Let cushions dry fully after getting wet, and follow the care guidance for the specific set you choose.
How do I choose the right size replacement cushion?
Measure the chair's inside seat width and depth, then compare those measurements with the cushion size. For shaped wicker seats, check the inner edges and shape as well as the outer width.
A 19 x 19 inch square cushion won't fit every chair, even if the seat looks close in size.
Can I machine wash Sunbrella patio cushion covers?
Care instructions vary by cushion. Supflourishia says its removable covers are machine washable, while RSH DECOR recommends spot cleaning Sunbrella fabric with mild soap and water.
Check the care directions for the exact set, and let covers air dry when instructed.
Do Sunbrella cushions come with foam inserts?
Many complete cushion sets include a fill, but cover-only sets don't. Snubbull's 14-piece option is covers only, so it requires existing inserts in matching sizes.
Check what each set includes before ordering, especially when replacing cushions and covers together.
