Key takeaways
- Covers: breathable covers prevent trapped moisture and mould. Avoid plastic sheets that cause condensation.
- Cushions: store them in a dry box or garage during winter and heavy rain.
- Feet: lift legs off wet ground with pads to prevent staining and rot.
- Cleaning: wash the frame twice a year with mild soap, then dry fully before covering.
The best garden sofa set for most households is a powder-coated aluminium frame with a polyethylene rattan weave and 4 to 5 inch quick-dry cushions, because it neither rusts nor needs refinishing. Resin sets such as the Keter Corfu are a lower-maintenance, lower-cost choice that avoids metal entirely, while teak and acacia suit buyers who accept yearly oiling. Pick the set by material and seating layout first, and by colour second.

Quick comparison of garden sofa set types
| Set type | Best for | Typical specs | Price range |
|---|---|---|---|
| Aluminium frame with PE rattan weave | Most gardens and patios, all-year use | Rust-proof frame, 4-5 in cushions, 4-6 seats | Mid to upper mid |
| Steel frame with PE rattan weave | Tight budgets | Heavier, powder-coated, can rust if chipped | Budget |
| Keter Corfu resin set | Low-maintenance, no metal | Three-seater sofa, two armchairs, small coffee table per DIY Garden roundup | Mid |
| Solid teak or acacia | Long-term investment, natural look | Needs oil or sealer once a year; heavy | Upper mid to premium |
| Corner sofa set with coffee table | Larger patios, dining and lounging | L-shape, 5-7 seats, modular sections | Mid |
| Two-seat or three-seat bistro-style sofa set | Balconies and small terraces | Compact footprint, 2-3 seats | Budget to mid |
Best overall: aluminium frame with a polyethylene weave
An aluminium frame does not rust, weighs less than steel, and survives rain, sun and salty air. Combined with a high-density polyethylene (PE) rattan weave, it gives a look similar to natural rattan without the cracking that comes with cheap PVC wicker. Look for a frame that is welded at the joints and a weave that is UV-stabilised, which means it is treated to fade slowly. The trade-off is price, and lightness: a light set can slide in strong wind, so choose a set with a weighted base or tie-down loops.
Best low-maintenance: Keter Corfu
A 2026 roundup from DIY Garden named the Keter Corfu its best value for money. The set includes a three-seater sofa, two armchairs and a small coffee table, and the review praised quick assembly and curved backrests that give a degree of lumbar support. It has no metal parts to rust. The reviewer also noted that the cushions mark easily, the plastic can get hot in direct sun, and the coffee table lacks a glass top. For a shady patio or covered porch it is an easy choice; for full sun, add light-coloured covers.
Best budget: steel-frame PE rattan sets
Steel-framed sets with a woven top cost the least per seat. The risk is rust where powder coat is chipped, especially at bolt holes. If you pick this route, buy a touch-up paint, store cushions indoors and cover the set in winter. These sets tend to be heavier, which helps in wind, but a rust-stained frame is hard to restore.
Best natural material: teak or acacia
Teak is naturally oily and resists rot, while acacia is cheaper and needs more care. Both need an annual coat of oil or sealer to keep their colour, or they can be left to weather to silver-grey. Wood sets are heavy, so they stay put but are hard to rearrange. They are a better long-term purchase than cheap rattan, but only for owners who will maintain them.
Best for large patios: corner sofa sets
Corner sets arrange modules into an L or U shape, with a coffee table in the middle. Seating counts are often optimistic: a nine-seat listing may mean nine places only when everybody sits tightly. Divide the advertised capacity by 1.5 for realistic comfort. A set that claims 8 seats usually seats five or six adults well.
Best for balconies: compact two- or three-seat sets
A small balcony needs a set about 28 to 32 inches deep and 55 to 70 inches wide. Look for folding or stackable pieces and a coffee table that doubles as a stool. Check weight limits on balcony floors, and ask building management if needed.
Frame material comparison
| Material | Rust risk | Weight | Upkeep | Typical lifespan |
|---|---|---|---|---|
| Aluminium, powder-coated | None | Light | Wipe clean | 8-12 years |
| Steel, powder-coated | Moderate if chipped | Heavy | Touch up chips | 3-6 years |
| Resin or plastic | None | Light to medium | Wipe clean | 5-8 years |
| Teak | None | Heavy | Oil yearly (optional) | 15+ years |
| Acacia | None | Heavy | Oil twice a year | 5-10 years |

How to choose: sizing and layout
Measure the space
Mark the footprint with tape on the ground. A three-seater sofa is usually 70 to 80 inches wide and 30 to 34 inches deep. Allow at least 30 inches between a sofa and a table or wall for walking.
Check the cushions
Look for 4 to 5 inch foam cores wrapped in quick-drying, UV-resistant fabric. Zippered covers are easier to wash. Reticulated foam drains faster than solid foam, which helps after rain.
Check the weave
Thicker, flat-section weaves tend to hold up longer than thin round strands. Ask whether the weave is made with high-density polyethylene.
Cover and store
Weather covers and storage boxes can add years. Store cushions during winter and heavy rain, even if they are water-resistant.
Cost per year: a worked example
If a steel set costs half as much as an aluminium set but lasts four years instead of ten, the aluminium set is cheaper per year of use. Add cover costs and replacement cushions, and the gap widens. For a rented flat where you may move in two years, the cheaper set makes sense.
Weatherproofing and winter care
- Covers: breathable covers prevent trapped moisture and mould. Avoid plastic sheets that cause condensation.
- Cushions: store them in a dry box or garage during winter and heavy rain.
- Feet: lift legs off wet ground with pads to prevent staining and rot.
- Cleaning: wash the frame twice a year with mild soap, then dry fully before covering.
Styling and layout ideas
Arrange the sofa so people face each other at a conversational distance of 6 to 8 feet, and keep a side table within arm’s reach. Weather-proof rugs define the seating zone and protect decking from table feet. In windy gardens, choose a heavier set or add weights to the frame. Shade from a parasol or pergola extends cushion life and keeps plastic seats cooler.
Reading listings: seat counts and sizes
Many retailers sell the same sets under different names, so compare dimensions and materials instead of titles. In the UK, rattan sets are usually labelled by seat count, such as 4 or 6 seater. In the US, the term patio conversation set is common. Measure the garden first: a 6-seat corner set typically needs about 8 by 8 feet, including walkway space.
Frequently Asked Questions
Which material lasts longest for outdoor sofas?
Teak and powder-coated aluminium last longest. Teak ages with oil or weathers to grey, while aluminium stays rust-free. Steel and cheap resin tend to last fewer years.
Are rattan garden sofas waterproof?
The weave itself is usually weatherproof, but cushions are only water-resistant and absorb moisture over time. Store them or use waterproof covers in heavy rain.
How many seats do I need?
Count your regular guests, then add one. For a family of four, a set with a three-seater sofa and two chairs works well; entertaining often points to a corner set.
Can garden furniture stay out in winter?
Aluminium, teak and resin frames can, but cushions should be stored. Use fitted covers and lift the legs off wet ground to reduce staining.
How do I clean a rattan set?
Brush off loose dirt, then wash with mild soap and warm water using a soft brush. Rinse and let it dry in the shade; avoid pressure washers on thin weaves.
