How to cover a garden swing for winter: dry it first

The patio is still dark from yesterday's rain, and the swing is where you left it in September. How to cover a garden swing for winter starts with the frame, ahead of the bag in the shed. Dry the steel or the wood, take loose cushions indoors, and only then put a cover over a bench that is staying outside.

A polyester canopy is the roof you sit under, and a winter cover is a separate skin for a bench that will not fit in a dry shed.

Products Compared checked two amazon.co.uk listings on 15 October 2026, the Outsunny freestanding swing and the Furinno hanging porch swing, against Merryhatton's winter-care notes, the Royal Horticultural Society page on garden seats, and Argos cover 133/7253 as a size clue. There was no laboratory test. A qualifying purchase through an amazon.co.uk link can earn us a commission at no extra cost to you, and the shelf prices below are from that scrape day.

In short

Dry the swing before any cover goes on. Store cushions in a dry shed or in the house, and use the canopy as shade rather than as winter protection. A cover sealed against wet paving can hold mould, and one winter in one garden is not a rust test.

The roof is not the cover

The canopy is shade and light rain while someone is sitting there. On the Outsunny three-seat swing, model 84A-110CG, the included-components line names that canopy, and a furniture cover is absent from the same line. On 15 October 2026 the amazon.co.uk listing showed a freestanding charcoal-grey A-frame, powder-coated alloy steel, a mesh seat, and an adjustable canopy, at £180.00, rated 4.3 from 64 reviews. The frame is 196 cm long, 128 cm wide and 172 cm high.

The listing does not say whether the canopy unclips, so leave it fitted. The cloth ends at the hem, and wind and weeks of damp still reach the mesh, the hardware, and the feet. Merryhatton's winter-care note treats a cover as its own product, used only once the furniture is dry. Ultraviolet wear happens in summer too, so a tired canopy stays tired in November.

If you are still choosing, a cushion set or a garden swing seat cover is the wrong first spend. You would own soft goods and still have nowhere to sit. The buying guide holds footprint, seat width, and box contents together, and the swing bench comparison keeps this Outsunny beside a hanging meranti porch swing. Pass on the freestanding swing when you need a winter cover supplied in the box.

Dry first

Cover the swing only when the frame is dry to the touch, including the underside. Merryhatton says the furniture has to be dry before a cover, and the RHS page on garden seats says you maintain seats when they are dry and treat rust where a coating has cracked. A cover slows the air. Moisture you shut in stays against mesh, wood, or steel until you peel the sheet back.

Pick a day when the paving has dried, then wipe the frame, the seat, and the underside. The Outsunny weighs 31.5 kg, so ask for a second person before you tip it to see the feet and the bolts. Leave it open until your hand comes away dry. A couple of bright, breezy hours is a rule of thumb, not a time from the listing or from Merryhatton.

The tidy mistake is the sheet pulled over a seat that still feels cool and damp. By the weekend the mesh can smell musty, and bolt heads can show a brown trace. Where a shed will take the whole frame, store the bench there and skip the outdoor cover.

The Furinno Tioman, model FG16409SC, is listed at 12 kg, but this page does not judge your porch. If the fixings are in doubt, leave the bench hanging, or ask a competent person before you take the load off.

Cushions and a breathable cover

Loose cushions spend winter in a dry shed or in the house. Merryhatton's indoor list is plastic, canvas, and cushions, because foam holds water. A garden swing seat cover over a soaked pad is a common way to find mould in spring. Neither listing includes a cushion. The Outsunny box line is the canopy, and the Furinno line is one porch swing. Pads you bought later still come inside.

If the bench stays on the patio, the cover has to breathe. Merryhatton's note on winter covers says a cover sealed shut can hold a damp climate, and mould follows. A polyethylene sheet on wet flags, hem in a puddle, is that climate. Leave a gap or use vents, and keep the hem off standing water. Moving air does not rescue a seat that went under the cover wet.

Argos swing chair cover 133/7253 is listed at £37, in polyethylene, at 180 × 205 × 135 cm, so check the live price. Pairing the largest sides in order leaves 9 cm, 8 cm, and 7 cm of spare on the Outsunny's 196 × 128 × 172 cm frame.

A hem and any travel past the feet can use that spare, and the listing does not state the swing arc. If your tape is longer on any side, choose another cover.

Buying the sheet or a cushion set before you own the bench is the wrong order. Choose the frame on the swing bench comparison first. Who each bench suits and porch or freestanding are separate decisions.

Metal chips and dry hardwood

Powder coat protects the steel until the coat breaks. Merryhatton says you touch up a damaged patch, and the RHS says you do that rust work on dry metal, where the coating has cracked. A fingernail chip with loose brown dust is the job.

Brush it while the steel is dry, paint it with an outdoor metal touch-up, and let the tin's stated drying time pass before a cover touches it. Wet paint under a sheet can peel away when you lift the cover in spring.

A holed tube, a cracked weld, or a slat split so the seat shifts is past a winter touch-up. Stop sitting on it. Colour on a bolt head is a smaller job than steel that has lost its wall.

The Furinno Tioman is oil-rubbed meranti, with teak oil named in the bullets, at £145.83 on 15 October 2026 and 4.3 from 555 reviews. Fresh oil goes on dry wood only, thinly, with the excess wiped off.

If water sits on cool, dark slats, leave the tin alone, because oil on damp meranti traps moisture. A porch roof does not make a wet November week dry, so wait, even if that means after November. This check only asks whether the wood is dry, and play-set anchors and ropes are a different product.

One winter is not a rust test

One Outsunny reviewer reported no frame rust after two winters, and a trace on the bolts. That is one garden, not a corrosion test, and it says nothing about salt air or a cover that stayed wet inside. The 4.3 from 64 reviews is a shop rating. Powder coat slows rust only where the coat is whole.

On the next dry spell, check bolt heads, the seat hardware, and anywhere the cover has rubbed. Rust that returns on the same chip means the paint did not seal it. A holed tube, or flaking across a leg, means you stop using the bench. A cover will not rebuild that steel.

Follow this order on a dry day, and finish each step before the next. Skip the oil on a steel frame, and skip the cover when a dry shed will take the bench.

1. Wait until the frame, the seat, and the canopy are dry underneath as well as on top.
2. Take loose cushions indoors until you sit outside again.
3. Paint bare metal only where the coat has cracked, once it is dry, and let it cure.
4. Oil hardwood only when it is dry, thinly, and wipe off the excess.
5. Fit a breathing cover clear of standing water, or store the frame in a dry shed.
