British weather doesn't pick sides. It rains sideways in June, freezes in March, and occasionally produces UV levels that would surprise people in much warmer countries. If you own garden furniture, you're essentially leaving it in one of the least predictable climates in Europe. The good news? With the right materials and a bit of regular maintenance, outdoor furniture can handle anything the UK throws at it for years.
This guide covers every material you're likely to find in garden furniture, what the British climate actually does to each one, and how to look after your furniture so it lasts.
Understanding What British Weather Does to Garden Furniture
Before we talk solutions, let's be specific about the problems. UK weather attacks outdoor furniture in four ways, and each needs a different response.
Rain and Moisture
The UK averages 1,150mm of rainfall per year, spread across roughly 150 rainy days. But the damage isn't just from rain hitting furniture — it's from persistent dampness. Morning dew, mist, and high humidity mean your furniture can be wet or damp even on days it doesn't rain. That constant moisture exposure is what causes rust on untreated metal, mould on fabric, and rot in unsealed wood.
Frost and Freezing
Water expands when it freezes. Any moisture that has seeped into cracks, joints, or porous materials will push those openings wider each time the temperature drops below zero. Over multiple freeze-thaw cycles — and we typically get 30-60 frost days per year depending on where you live — small cracks become structural weaknesses.
UV Radiation
Even in the UK, cumulative UV exposure fades colours, breaks down plastic polymers, and dries out wood. South-facing gardens are hit hardest. UV damage is slow and invisible until you notice that your black rattan looks dark grey, or your teak bench has gone silver. It's not always bad — some people prefer weathered teak — but it's worth knowing it will happen.
Wind
Wind is the most underestimated threat. A gust can pick up a lightweight chair and throw it across a garden, into a window, or onto your car. Even furniture that stays put gets stressed by constant wind rocking it, loosening joints and fixings over time. Coastal areas and exposed hilltop gardens are especially vulnerable.
Material-by-Material Breakdown
PE Rattan (Polyethylene Rattan)
PE rattan is the most weather-resistant furniture material you can buy. It's synthetic, so it doesn't absorb water, doesn't rot, and won't swell or crack in frost. UV-stabilised PE rattan (which is what all our furniture uses) resists fading and won't become brittle in sunlight.
All of our egg chairs, conversation sets, lounge sets, and cube dining sets use hand-woven PE rattan over steel or aluminium frames. The rattan itself needs minimal maintenance.
Care requirements:
- Wash with warm soapy water and a soft brush 2-3 times per season
- Rinse thoroughly and let air dry
- Check for loose strands and trim with scissors if any are pulled free (this prevents further unravelling)
- No special treatments, oils, or sealants needed
Winter: PE rattan can stay outside all winter without damage. However, covering it will keep it cleaner and reduce the spring clean-up effort.
Powder-Coated Steel
Steel is the most common frame material for garden furniture, including hanging egg chairs and many patio sets. Raw steel rusts quickly in damp conditions, which is why garden furniture uses powder-coated steel — the frame is coated with a layer of electrostatically applied powder that's then baked at high temperature to form a tough, protective shell.
Powder coating is effective, but not indestructible. Chips and scratches in the coating expose bare steel to moisture, and once rust starts at a chip, it spreads underneath the coating from that point.
Care requirements:
- Inspect the coating at the start and end of each season, paying attention to joints, bolt holes, and areas where the frame contacts other surfaces
- Touch up any chips or scratches immediately with a metal primer followed by matching paint (or use a touch-up pen designed for metal furniture)
- Clean with soapy water and dry thoroughly — don't let water pool in frame joints
- If surface rust appears, sand it back with fine-grit sandpaper (240 grit), apply rust converter, then repaint
Winter: Cover steel-framed furniture or move it under shelter. Persistent winter moisture combined with freeze-thaw cycles accelerates rust at any point where the coating is compromised.
Aluminium
Aluminium doesn't rust. That alone makes it one of the best frame materials for UK gardens. It does oxidise — you'll sometimes see a dull white powdery film on old aluminium — but this oxidation layer actually protects the metal underneath from further corrosion.
Aluminium is also lighter than steel, which is both an advantage (easier to move) and a disadvantage (more likely to blow over in wind). Some of our bistro sets use aluminium frames for this reason — the lighter weight makes them easy to fold and store.
Care requirements:
- Wash with soapy water and a soft cloth
- For oxidation marks, use a specialist aluminium cleaner or a paste of bicarbonate of soda and water
- Don't use steel wool or abrasive pads — they'll scratch the surface
- If the frame is painted or powder-coated, treat chips as you would on steel
Winter: Aluminium can stay outside year-round without structural concern. Cover it to keep it clean, but there's no urgency compared to steel.
Wood (Hardwood and Softwood)
We don't sell wooden furniture at Rosewood & Stone — we specialise in PE rattan and metal-framed pieces — but many of our customers have wooden furniture alongside our products, so it's worth covering.
Hardwoods (teak, eucalyptus, acacia): These are naturally weather-resistant due to high oil content. Teak in particular can last decades outdoors without treatment. However, all hardwoods will turn silver-grey over time if untreated. If you want to keep the original colour, you'll need to apply teak oil or a specialist hardwood oil at least twice a year.
Softwoods (pine, spruce, cedar): These need more protection. Untreated softwood will rot within 2-3 seasons in a UK garden. Pressure-treated softwood lasts longer but still needs annual retreatment with a wood preservative. Cedar is the most resistant softwood, but even cedar benefits from annual oiling.
Care requirements:
- Clean with a stiff brush and soapy water in spring
- Sand lightly if the surface feels rough or splintered
- Apply appropriate oil, stain, or preservative based on the wood type
- Tighten all bolts and screws — wood expands and contracts with moisture changes, loosening fixings over time
Winter: Cover wooden furniture or move it to a dry shed. At minimum, get it off direct ground contact — standing water at the feet of wooden furniture accelerates rot dramatically.
Fabric Cushions
Cushions are the weakest link in any outdoor furniture setup. The filling absorbs water, the fabric can grow mould, and UV light fades colours and weakens fibres. Every piece of cushioned furniture we sell — from the Cotehele egg chair to the Cliveden 5-piece lounge set — comes with cushions that have removable, machine-washable covers. That's non-negotiable in our view.
Care requirements:
- Remove cushions from furniture when not in use, especially if rain is expected
- Machine wash covers at 30°C at least twice per season
- Spot-clean stains promptly with mild detergent and a damp cloth
- If the foam insert gets wet, stand it on its edge in a warm, well-ventilated area until fully dry — do not lay it flat, as this traps moisture
- Never tumble dry foam inserts
Winter: Bring all cushions indoors. No cover will fully protect them from months of persistent moisture. Store them standing upright in a dry cupboard, shed, or garage.
Covers vs Storage: The Great Debate
Should you cover your garden furniture or bring it inside for winter? This argument runs every October in garden forums across the country. Here's our honest take.
Furniture Covers
Pros:
- Quick and easy — throw the cover on, tie it down, done
- Furniture stays assembled and in place, ready for an unseasonably warm day in February
- Good covers are waterproof and UV-resistant
- Much cheaper than building storage space
Cons:
- Condensation can build up under covers, trapping moisture against the furniture
- Covers themselves deteriorate — UV, wind, and rain break them down over time, and a torn cover is worse than no cover
- Wind can pull covers off or fill them like sails, moving lightweight furniture underneath
- They don't protect against frost if moisture is already trapped inside
Our recommendation: Use covers made from breathable, waterproof fabric (not plain tarpaulin). Ensure they have ventilation flaps or mesh panels to prevent condensation. Tie them down securely — bungee cords under the base work well. Check them monthly and remove any standing water that pools on top.
Indoor Storage
Pros:
- Complete protection from all weather
- Furniture lasts significantly longer — potentially decades
- No condensation issues
- No risk of wind damage
Cons:
- You need space. A Blickling 9-piece cube dining set takes up a lot of shed space, even when cubed up
- Disassembly and reassembly each season is time-consuming
- Heavy items like double egg chairs are difficult to move
- Most people simply don't have a large enough garage or shed
Our recommendation: Store cushions indoors. Always. For the furniture itself, indoor storage is ideal if you have the space, but PE rattan furniture covered with a decent waterproof cover will survive UK winters without issue. The frames are powder-coated steel, and the rattan doesn't absorb moisture. A cover is sufficient.
The Practical Middle Ground
Most of our customers do this: cushions come inside for winter, furniture stays out with a cover. In spring, they wash the furniture, check for any chips in the frame coating, and put the cushions back out. It takes an hour or two, twice a year, and keeps everything in good shape for season after season.
Seasonal Care: A Month-by-Month Guide
March–April: Spring Preparation
- Remove winter covers and wash the furniture with warm soapy water
- Inspect all frames for chips, scratches, or surface rust. Touch up as needed
- Check all bolts and tighten any that have loosened
- Wash cushion covers (they'll have been stored since autumn — a refresh helps)
- Place cushions on furniture and check for comfort — replace any foam that's gone flat
- Apply wood oil to any wooden furniture in your garden
May–June: Early Season
- Furniture should be in full use by now
- Get into the habit of bringing cushions in if overnight rain is forecast
- Wipe down furniture weekly to prevent pollen and bird dropping build-up (both stain if left)
- Check that egg chair hanging mechanisms (chains, carabiners, S-hooks) are secure
July–August: Peak Season
- Mid-season wash: give all furniture a thorough clean in July or August
- Machine wash all removable cushion covers
- If you notice UV fading on cushions, consider repositioning the furniture so it gets afternoon shade rather than full sun all day
- Tighten bolts again — increased use means increased loosening
- Water any potted plants near furniture carefully — soil-stained water running onto rattan or metal is harder to clean once dried
September–October: End of Season
- Final deep clean of all furniture
- Remove all cushions, wash covers, dry thoroughly, store indoors standing upright
- Touch up any frame chips or scratches before covering — don't let bare metal face winter unprotected
- Fit winter covers and secure with ties or bungee cords
- If you have lightweight furniture (bistro sets, rocking chairs), consider bringing these indoors entirely — they're light enough to store easily and light enough for wind to damage
November–February: Winter
- Check covers monthly — ensure they haven't blown loose, torn, or accumulated standing water
- Brush off snow if it accumulates heavily on covered furniture (weight can stress frames)
- If you get an unexpectedly warm winter day and want to sit outside, go for it — but bring the cushions back in before evening
- Don't store cushions in unheated garages or sheds where they can get damp from condensation. A cupboard inside the house is better
Product-Specific Advice from Our Range
Egg Chairs (All Types)
The PE rattan pods on our single and double egg chairs handle weather well. The most vulnerable point is the top of the hanging frame where the hook or eyebolt sits — water can pool here and work its way into the frame tube. When covering your egg chair, make sure the cover sits high enough to shed water off the frame apex rather than letting it pool.
For standing egg chairs like the Waddesdon or Tyntesfield, the base is the area to watch. Standing water around the base encourages rust, so position them on a well-drained surface. If they're on decking, make sure the decking drains properly.
Rocking Egg Chairs
The Studley (£99.99) and Fountains (£169.99) rocking chairs have curved runners that sit directly on the ground. These runners can trap moisture underneath, so flip the chairs onto their backs periodically to let the runners dry, or prop them up on their side when not in use.
Bistro and Folding Sets
Our bistro sets like the Hidcote folding set (£199.99) are designed to fold flat. This is a genuine advantage for winter — fold them up and store them vertically in a shed or against a garage wall. They take up minimal space when folded and are completely protected from weather.
The Nunnington, Sissinghurst, and Stourhead 3-piece sets (£219.99 each) can also be stored compactly. Their smaller size makes indoor storage practical where it wouldn't be for larger furniture.
Conversation and Lounge Sets
The Claydon (£319.99) and Polesden (£319.99) conversation sets and the larger Cliveden 5-piece lounge set (£699.99) and Brimham (£849.99) are too large to bring indoors for most people. Cover them well and bring the cushions inside. The PE rattan and steel frames will be fine under a properly fitted cover.
Dining Sets
Cube dining sets like the Blickling 9-piece (£699.99) have a clever advantage: the chairs tuck under the table to form a compact cube. In this position, only the outer surfaces are exposed to weather. Cover the cubed-up set and the inner surfaces — including the chair cushions if you've left them in place — stay dry. That said, we'd still recommend removing the cushions for winter storage.
Corner dining sets like the Montacute (£699.99) are harder to cover neatly due to their L-shape. You may need a specifically shaped cover rather than a generic rectangular one.
Common Mistakes That Shorten Furniture Life
After years of hearing from customers, these are the most common errors we see:
- Using a pressure washer on rattan. The high-pressure stream can force water behind the weave, loosen individual strands, and strip UV-protective coatings from PE rattan. Use a garden hose and soft brush instead.
- Leaving cushions out "just for one night" repeatedly. One rainy night won't ruin a cushion. But a habit of leaving them out leads to cumulative moisture absorption, and eventually mould. Be honest with yourself — if you won't bring them in reliably, buy a waterproof cushion storage box.
- Covering furniture while it's still wet. Putting a cover over damp furniture traps moisture against it. Always let furniture dry before covering.
- Ignoring small chips in frame coating. A 2mm chip in powder coating becomes a 20mm rust spot within one winter. Keep a touch-up pen handy and address chips when you spot them.
- Storing wooden furniture on a concrete floor. Concrete wicks moisture upward. Store wooden furniture raised off the floor on bricks or pallets.
- Using bleach-based cleaners on PE rattan. Bleach can discolour the rattan and weaken it over time. Stick to mild washing-up liquid and warm water.
What "Weatherproof" Actually Means
No garden furniture is completely maintenance-free. When manufacturers (including us) describe furniture as "weatherproof" or "weather-resistant," they mean the core materials — PE rattan, powder-coated steel, aluminium — can withstand outdoor exposure without structural failure. They don't mean you can ignore it entirely.
Think of it like a car. A modern car is built to handle rain, sun, and cold. But you still wash it, check the tyres, and get it serviced. Garden furniture is the same. The better the materials, the less maintenance it needs — but some is always required if you want it to last.
All our furniture at Rosewood & Stone is built from materials chosen specifically for UK outdoor use. PE rattan, powder-coated steel, and UV-resistant fabrics go into every product. But we'd rather be honest about care requirements than pretend you can leave anything outside for years without touching it.
A bit of effort each spring and autumn. That's genuinely all it takes. Look after it properly and you'll spend your summers sitting in it rather than shopping for a replacement.
