Replacement Garden Cushions Worth Buying: 5 UK Picks to Revive Rattan and Benches (£42 to £245)
The rattan sofa is fine. The cushions are knackered. Five replacement garden cushion sets I'd actually order — from a £46 bench pad to a £245 full 14-piece set.
The rattan sofa is fine. The cushions are knackered. The covers have faded to a sort of grey-beige no matter what colour they started as, the foam pads have flattened into pancakes, and the back ones never stay put. I went round this exact loop last spring with a four-year-old corner set that's structurally perfect and aesthetically tragic, and the maths is unambiguous: a 14-piece replacement cushion set runs about £60-£245, while a like-for-like new corner sofa is £600 minimum. So you keep the frame and replace the soft kit.
What's tricky is that "garden cushion" covers wildly different products. Some are 8 cm seat pads with corner ties. Some are 10 cm segmented sun-lounger mattresses. Some are covers-only - no foam - for refreshing pads you've still got. Buy the wrong one and you've wasted a weekend.
If you only read this: for a standard 120 cm bench, the £46 grey bench cushion is the obvious pick. If the foam in your rattan corner sofa is fine and only the covers are gone, the £67 cover-only set is genuinely clever.
How I'm thinking about this
A few rules I'd apply to anything in this category:
Polyester at 200 gsm or above. Thinner than that and the cover frays at the zip and the colour goes within a season.
Foam at least 8 cm on seats, 10 cm on loungers. Thinner than that and you'll feel the frame.
Tie fastenings if it's anywhere breezy. The cushion will slide off otherwise.
Water-resistant, not waterproof. Nothing in this list survives a wet Manchester October left outdoors. All of them want a cushion box or a covered conservatory in winter.
Measure the bench, sofa or chair first. Returns on bulky soft furnishings are a faff and most suppliers won't refund postage.
1. Grey 2-Seater Garden Bench Cushion 120 cm - the cheapest one that's still worth it (£45.99)
If you've got a standard 120 cm bench - and most metal or hardwood two-seaters in UK gardens are precisely 120 - this is the one to order without overthinking. The 8 cm sponge filling is generous for the price, the polyester cover handles splash and brief showers, and the corner ties stop it sliding off when you stand up.
The honest bit: it's a single seat cushion with no backrest, and the grey is closer to "warship" than "Farrow & Ball". You're paying for fit and function, not styling. Don't expect it to look like something out of Cox & Cox.
2. Premium 4-Piece Black Outdoor Seat Cushion Set with Ties - the dining-chair refresh (£58.99)
For the metal bistro or hardwood dining set whose seats are murder after twenty minutes, this four-pack adds 8 cm of cushioning across all four chairs for under £60. Black is the most forgiving colour for garden use - dust, mud, the inevitable splash of red wine - and the ties wrap around most chair backs without faff.
Where it falls down: at this price point the cover isn't zip-off for the washing machine - when it stains you sponge it. If your dining set sees a lot of toddlers and squash bottles, factor that in.
3. Premium Dark Grey Rattan Cushion Covers, 14-Piece - covers only, the smart middle ground (£66.99)
This one's a category outlier. It's just the covers - no foam pads - so you're buying it because your existing rattan corner sofa's foam is still fine and you only need to refresh the fabric. At £67 for fourteen pieces with zips, that's under £5 per cover. A like-for-like set with new foam costs three times this.
Read the dimensions twice before ordering. Standard rattan corner sets vary by 5-10 cm across brands, and these covers fit one specific size range. If yours is bigger or smaller, you'll either be wrestling fabric over too-large pads or staring at gaping zips on too-small ones.
4. Light Grey Sun Lounger Cushions, Set of Two - the upgrade for proper lying down (£95.99)
If you've ever actually fallen asleep on a plastic-slat sun lounger you'll know they're useless after twenty minutes - the slats print into your back like a pencil grid. These segmented cushions are 10 cm thick on a 220 gsm cover with six tie points, and the articulation matches the lounger's recline positions properly. For two cushions at under £100, it's the best comfort upgrade in this list.
Caveat: they're sized for the more common UK lounger frames, so check yours measures roughly 190-200 cm end to end. They're also bulkier than the dining cushions when packed away - clear a shelf in the shed or accept they'll live indoors over winter.
5. 14-Piece Black Garden Furniture Cushions - the splurge that replaces everything (£244.99)
When the covers and the foam are both gone, this is the proper full-replacement set. Fourteen pieces, dual-fill construction, 8 cm on both seat and back pads, zip-off covers for the washing machine. £245 sounds steep until you compare it with replacing a six-seat rattan corner sofa, which starts north of £600 even for the budget brands.
Two things. Measure your existing sofa carefully against the listed dimensions - corner sets vary. And the supplier rates these as water-resistant, not waterproof, which means the same winter-storage rule applies as everything else here. You're not saving £400 just to leave them out in October.
What to actually check before ordering
Seat length AND width in centimetres. Don't trust "two-seater" - measure.
Tie position against your chair frame. Cushions with corner ties only work if your chair has somewhere to tie them.
Cover removability. Sets without zips can't go in the machine.
Storage plan. Where do these live from October to April? If the honest answer is "in the shed where the lawnmower lives," buy the cheaper set.
Postage class. Anything over 2 kg ships courier rather than Royal Mail - check the timescale if you need it for a specific weekend.
The verdict
If you've got a 120 cm bench and £50 to spend, the grey bench cushion is the obvious pick - it does one thing well. If you're refreshing a rattan corner sofa where the foam's still fine, the £67 cover-only set is the cleverest bit of value in the list. And if the foam's gone too, the £245 full 14-piece set is the right call - paying twice as much in two years is not the saving you think it is.

The first garden set I bought in this country lasted exactly one autumn. Six years and three replacements later, here are five pieces I'd actually live with.
