The best outdoor bench cushions for common seats

The best fit depends on your bench dimensions and how much weather reaches the seat. These picks cover common rectangular sizes, thicker padding and several ways to keep a cushion in place.

We compared the stated sizes, fill, cover material, fastening and care details against the needs of outdoor bench seating. Our score weighs specs, features and buyer feedback against what you're shopping for.

idee-home Outdoor Bench Cushion Waterproof: Best for a 48 x 18 in bench

9.7/10Our score

• 48 x 18 in
• 3 in high-density foam
• Waterproof PU-coated polyester cover
• Ties and hidden zipper

A common bench size, high-density foam and ties make this a straightforward fit for many rectangular seats. The removable cover has a hidden zipper.

See it on Amazon

Pros

• Common 48 x 18 in size
• Waterproof PU-coated cover
• Ties help hold it in place

Cons

• Measure your seat before ordering
• The cover is intended to stop splashes, not replace covered storage in severe weather

The 48 x 18 in size makes this idee-home cushion a practical starting point for many rectangular patio and porch benches. Its high-density foam is 3 in thick, and attached ties help secure it to the frame.

The cover is 300GSM polyester with a waterproof PU coating. The hidden zipper lets you remove it for washing, which is useful when outdoor dust and everyday spills call for a deeper clean.

For a stretch fit over an existing cushion, compare stretch outdoor cushion covers with its measurements.

Measure the seating area rather than relying on the bench's overall width. A backrest, arms or curved ends can reduce the flat surface available for the cushion.

Choose this one if your seat is close to 48 x 18 in and you want ties plus a removable cover. For a closer look at other weather-focused choices, see our best outdoor bench cushion waterproof options.

2

Summsun Outdoor Bench Cushion Pad: Best for firm foam support

9.6/10Our score

• 48 x 18 in
• 3 in thickness
• 28D high-density sponge
• Removable machine-washable cover

This 48 x 18 in cushion uses firm 28D foam and a removable cover. Summsun recommends bringing it indoors or covering it during heavy rain.

See it on Amazon

Pros

• Common rectangular size
• High-density foam
• Machine-washable cover

Cons

• Allow time for compressed foam to expand
• Water-repellent rather than a stated fully waterproof design

Summsun fits the same 48 x 18 in footprint with 3 in of firm, 28D high-density sponge. That firm fill may suit you if you prefer a less plush seat than a soft, tufted pad.

The 250gsm polyester cover has a water-repellent coating. Summsun recommends indoor storage or a cover during heavy rain, so plan for storage if the bench is exposed.

A hidden zipper makes the cover removable for machine washing. The cushion arrives compressed, and Summsun advises allowing it time to expand before use.

Pick it for a firm 48 in pad and washable cover. If color is part of your decision, compare it with our guide to best outdoor bench cushion green picks.

3

Favoyard Outdoor Bench Cushion: Best for a 42 in bench

9.4/10Our score

• 42 x 18 in
• 3 in sponge
• 300GSM polyester cover with TPU coating
• Ties on both sides

The shorter 42 x 18 in shape suits benches that are too small for a 48 in cushion. Its cover has a hidden zipper, and ties attach it to the seat.

See it on Amazon

Pros

• Useful shorter length
• 3 in padding
• Machine-washable cover

Cons

• Check the full seat area before choosing
• Favoyard's color-fastness statement is a brand claim

Favoyard is a 42 x 18 in option for a bench that is too short for the 48 in picks. Its 3 in sponge fill and ties on both sides give you a familiar rectangular pad with a way to secure it.

The polyester cover has a TPU coating and a hidden zipper. Favoyard says its fabric is designed for color fastness, and the cover can be machine washed.

Check the bench's flat seat length and depth before choosing this size. A 42 in cushion may still overhang a narrow frame, even if the overall bench width seems close.

Choose Favoyard when 42 x 18 in matches your seat and you want ties. For benches with a curved front or back, use our guide to the best curved bench outdoor cushion.

4

IASEAHK Outdoor & Indoor Bench Cushion: Best for extra-thick padding

9.3/10Our score

• 48 x 18 x 5 in
• Mixed foam fill
• Non-slip bottom and straps
• Water resistant

At 5 in thick, this cushion gives buyers a deeper pad than the 3 in options. Its mixed fill includes cooling gel memory foam, high-density foam and down-alternative filling.

See it on Amazon

Pros

• 5 in thickness
• Non-slip bottom plus straps
• For indoor and outdoor use

Cons

• Water resistance is not full waterproofing
• Spot clean with mild soap and water

IASEAHK offers 5 in of thickness, two inches deeper than the 3 in pads above. The 48 x 18 in cushion has mixed fill that includes cooling gel memory foam, high-density foam and down-alternative filling.

Its double non-slip design combines a bottom layer with two straps. That may help on a smooth bench seat, although the frame still needs a suitable place to attach the straps.

The 300GSM polyester Oxford cover is described as 80% water resistant, not fully waterproof. Spot clean it with mild soap and water, then allow it to air dry.

Pick this cushion if extra thickness is your priority and the 48 x 18 in footprint fits. Consider it for a covered spot if regular rain reaches your bench.

5

Comcaver Outdoor Bench Cushion Waterproof 42 x: Best for a waterproof 42 in fit

9.2/10Our score

• 42 x 18 x 3 in
• TPU-coated Oxford fabric
• 30D high-resilience sponge
• Two ties

Comcaver combines a 42 x 18 in shape with a TPU-coated cover and two ties. Its 30D high-resilience sponge is described as firm.

See it on Amazon

Pros

• Specific 42 x 18 in size
• Waterproof cover
• Ties help limit shifting

Cons

• Teal is the stated color for this pick
• Compare the seat shape and tie position before ordering

Comcaver pairs a 42 x 18 x 3 in size with a TPU-coated Oxford cover and two ties. Its 30D high-resilience sponge has a firm feel.

The waterproof cover may suit a bench that sees splashes, while the ties help limit movement during use. Comcaver also describes the fabric as UV resistant, with a color-fastness statement from the brand.

Choose it if your bench needs the shorter 42 in length and you want a waterproof cover. The stated color for this pick is teal, so check that it works with your outdoor setting.

6

IPYNBAP Bench Cushion: Best for a narrower 42 in seat

9.1/10Our score

• 42 x 16 x 4 in
• Shredded foam
• Non-slip bottom and ties
• Not waterproof

The 16 in depth suits a narrower bench seat than the 18 in options. Its bottom is non-slip and it also has ties, but the cushion should stay out of the rain.

See it on Amazon

Pros

• Narrower 16 in depth
• Non-slip bottom and ties
• Tufting helps limit fill bunching

Cons

• Not waterproof
• Allow 24–48 hours to expand after unpacking

IPYNBAP has a 42 x 16 in footprint, making it narrower in depth than most picks here. The 4 in cushion uses shredded foam, with tufting intended to keep the fill from bunching.

A non-slip bottom and string ties give it two ways to stay in place. It is also described for indoor and outdoor use, but the care notes say it is not waterproof and should stay out of the rain.

Machine wash or wipe stains with a damp cloth. Allow 24–48 hours for the cushion to expand after unpacking.

Choose it when a 16 in depth better matches your seat. Avoid it for an uncovered bench where rain can soak the cushion.

7

Codi Outdoor Bench Cushion for Patio Furniture: Best for adjustable straps

8.8/10Our score

• 48 x 18 x 3 in
• High-density foam core
• 600D Oxford cover
• Adjustable elastic straps

Adjustable elastic straps wrap around a furniture frame, which can help keep this 48 x 18 in cushion in place. The cover has a zipper for removal.

See it on Amazon

Pros

• Adjustable straps
• 3 in foam core
• Removable machine-washable cover

Cons

• Allow up to 48 hours to expand
• Confirm the strap setup works with your bench frame

Codi is a 48 x 18 x 3 in cushion with adjustable elastic straps that wrap around the furniture frame. The 600D Oxford polyester cover has a water-resistant surface coating.

The high-density foam core is 3 in thick, and the cover unzips for machine washing. Codi advises allowing up to 48 hours for the cushion to expand after unpacking.

The straps may be useful when a bench has a frame that lets them wrap around securely. Check for that attachment space before choosing this design.

Pick it if you want adjustable straps on a common 48 in size. For a separate cover to protect a pad you already own, compare best outdoor bench cushion covers waterproof and best outdoor bench cushion covers.

8

SUNROX LokGrip Non Slip Tufted Memory Foam: Best for covered benches

8.5/10Our score

• 36 x 14 x 4 in
• Gel memory and high-density foam blend
• LokGrip non-slip backing
• Spot clean only

SUNROX is a smaller option for a covered porch bench or indoor seat. Its non-slip backing replaces ties, and the care guidance calls for spot cleaning.

See it on Amazon

Pros

• Non-slip backing
• Tufted foam blend
• Suitable for covered outdoor benches

Cons

• Smaller 36 x 14 in size
• Bring it inside when it rains

SUNROX is smaller at 36 x 14 in, so it suits a compact seat or a bench with a covered location. Its tufted cushion uses a gel memory and high-density foam blend, with a LokGrip textured backing instead of ties.

The stated care is spot cleaning with mild soap and water. SUNROX recommends bringing it indoors when it rains or when it is not in use.

The listed size is much shorter and shallower than the 42 and 48 in options. Measure carefully so it covers enough of the seat for your preferred position.

Choose it for a covered bench where a non-slip bottom is useful. If your bench material affects where it sits, see our guides to Is Poly Lumber Good for Outdoor Furniture? and [Is Bamboo Good for Outdoor Furniture?

FUNHOME Outdoor Bench Cushion 45 x18 inch: Best for a tufted 45 in seat

8.0/10Our score

• 45 x 18 x 5 in
• Tufted PP cotton fill
• Non-slip grips
• Water resistant

The 45 x 18 in size and tufted fill suit buyers who want a deeper pad between common 42 and 48 in lengths. Grips on the underside help reduce sliding without ties.

See it on Amazon

Pros

• 5 in thick
• Non-slip grips
• Tufted design

Cons

• Water resistant, not stated as fully waterproof
• Allow up to 72 hours to expand

FUNHOME fills the middle ground between the 42 and 48 in options with a 45 x 18 x 5 in shape. Its tufted PP cotton fill is thicker than the 3 in cushions, and grips on the underside help reduce sliding without ties.

The cover is described as water resistant, and FUNHOME says water beads up on it. That does not make it a fully waterproof choice, so bring it in or cover it when heavy rain is expected.

Allow up to 72 hours for the compressed cushion to regain thickness. Choose it if the 45 in length fits your bench and you want a deep, tufted pad.

How do you measure a bench for an outdoor cushion?

Measure the flat seating surface from side to side and from front to back. Compare those dimensions with the cushion's stated length and depth before considering color or fill.

Include obstacles in your check. Arms, slats, a curved edge or a raised backrest can change how much usable seat remains.

A cushion that is slightly smaller than the seat may leave a narrow border uncovered. A cushion that is too large can overhang, bunch or interfere with the frame.

For common lengths, compare best 48 inch outdoor bench cushion and best 60 inch outdoor bench cushion options. If you need a specific footprint, see best outdoor bench cushions 48 x 18, best outdoor bench cushion 40 x 18 and best outdoor bench cushion 42 x 18.

What cushion thickness works for an outdoor bench?

Choose thickness by the seat height and how much padding you want, then check that your feet still rest comfortably when seated. The picks here range from 3 to 5 in thick.

A thicker cushion changes your sitting height more than a slim pad. If the bench has a backrest, check how the added height affects your position and whether the cushion can fit beneath it.

For a cushion with a built-in back, see our guide to the best outdoor bench cushion with backrest. For a similar length used indoors, compare best bench cushions indoor 48 inch.

Should an outdoor bench cushion be waterproof?

Choose a waterproof cover if the bench gets splashes, but plan to store cushions during heavy rain or long periods of non-use. Water resistant means some moisture protection, not that a cushion should stay wet outdoors.

The options here use different terms and materials. Idee-home describes a waterproof PU coating, Comcaver uses a TPU-coated cover, and IASEAHK describes its cover as 80% water resistant.

For a bench under an awning, a water-resistant or spot-clean option may be enough. On an exposed patio, removable covers and indoor storage can make care more manageable.

Do ties or non-slip backing keep cushions in place?

Ties work when the bench frame gives you a secure place to attach them. A non-slip bottom or grip can help on a smooth seat, and some cushions combine a grippy base with straps.

Check the underside of your bench and the cushion fastening layout before buying. A cushion can shift if ties cannot reach a frame rail or if the seat surface does not give the backing enough contact.

How do you clean and store outdoor bench cushions?

Follow the care method for the cushion you choose. Some have removable machine-washable covers, while others call for spot cleaning.

Let a washed cover dry as directed before putting it back on. Store cushions indoors or in a dry box when heavy rain, winter weather or long periods without use are expected.

Which outdoor bench cushion should you choose?

Pick idee-home for a 48 x 18 in seat, ties and a removable cover. Choose Summsun for a firm 48 in pad, Favoyard or Comcaver for a 42 in seat, and IASEAHK if you want 5 in of thickness.

Measure the bench first, then match the cushion's size, fastening and care to its location. Explore the full outdoor cushions buying guide if you're comparing bench pads with other patio seating cushions.

Which size outdoor bench cushion should I buy?

Buy a cushion close to the flat seating area's length and depth. Measure the usable seat, not the bench's total outside width, since arms and curved edges can reduce the space available.

Compare the cushion size with that measurement before ordering. A 48 x 18 in cushion is too large for a bench with only 42 in of flat seating.

Can I leave an outdoor bench cushion in the rain?

That depends on the cover, and even waterproof or water-resistant fabric does not make storage unnecessary. Some covers are designed to repel water, while others should stay dry.

Bring cushions inside during heavy rain or long periods of non-use. This helps limit moisture buildup in the cover and foam.

Are thicker outdoor bench cushions more comfortable?

A thicker cushion adds more padding, but it also raises your seated position. Check whether your feet still reach the ground and whether a backrest leaves room for the cushion.

The options here range from 3 to 5 in thick. Choose by the seat height and fit you want, not thickness alone.

How can I stop a bench cushion from sliding?

Use ties or straps if they can attach securely to the bench frame. A non-slip backing or underside grips can also help reduce movement on a smooth seat.

Check the bench construction before choosing the fastening type. A cushion may shift if its ties cannot reach a frame rail or its base has little contact with the seat.

Can I use an indoor bench cushion outside?

Use a cushion outdoors only when its materials and care guidance fit the conditions where it will sit. Some cushions are intended for indoor and outdoor use, while some are best for covered benches.

Keep cushions dry when rain is expected, and follow their cleaning instructions. For indoor seating ideas, see our best bench cushions indoor 48 inch guide.

Frequently asked questions

How do I choose an outdoor bench cushion size?

Measure the flat seating area, including its length and front-to-back depth. Compare those measurements with the cushion dimensions, then account for armrests, curved ends and any overhang you want.

A cushion should sit securely without blocking the bench frame or extending into a walkway.

Are outdoor bench cushions waterproof?

Some have waterproof covers, while others are water resistant or intended for covered benches. For example, IASEAHK describes its cover as 80% water resistant, and IPYNBAP says its cushion is not waterproof.

Bring cushions indoors during heavy rain or long periods without use.

Are ties or a non-slip bottom better for a bench cushion?

Ties attach to parts of the bench frame, while a non-slip bottom relies on grip against the seat. Some cushions use both, such as the IASEAHK option.

Check whether your bench has a good place for ties and whether the seat surface is smooth before choosing.

Can I machine wash an outdoor bench cushion?

Care depends on the cover. Idee-home, Summsun and Favoyard describe removable covers that can be machine washed, while SUNROX calls for spot cleaning.

Check the care directions for your chosen cushion and let a washed cover dry as directed before putting it back on.

What should I do with a cushion in winter?

Store it indoors or in a dry storage box during winter, heavy rain or long periods of non-use. This helps limit moisture buildup and keeps the cushion from staying wet between uses.

A water-resistant cover does not make an uncovered bench cushion suitable for every weather condition.
