Marketplace Roulette: How to Vet Second-Hand Garden Furniture Like Someone Who's Been Burned Before

There is a particular strain of Sunday-evening optimism that arrives with a cup of tea and a Marketplace scroll, when a six-seater teak table appears for eighty quid in a village twenty minutes down the road. The photos look decent. The photos always look decent. What they never show is the underside of the table top, where water has been sitting since 2014.

Buying garden furniture second-hand is one of the last genuinely good deals in British outdoor living. Good hardwood frames outlive their first owners by decades, and a set that cost well over a thousand pounds new really does turn up for the price of a decent lunch. The trouble is that the gap between a bargain and a burden is far narrower than the listings suggest, and the difference is almost entirely in the places the seller hasn't photographed.

Why the used market is worth the faff in 2026

New teak is expensive and has stayed expensive. Even mid-range hardwood sets have crept up, while the cheap end of the market is dominated by thin-section timber and tubular steel that will not see out a decade. Meanwhile there is a steady supply of decent pre-owned furniture coming out of gardens in every postcode: house moves, downsizing, probate sales, and the very British habit of buying a set, using it twice, and covering it with a tarp for eleven years.

You are not being cheap by buying used. You are buying a frame that has already proved it can survive a British winter, which is more than can be said for a lot of the flatpack on offer.

Start at the joints, not the timber

Everyone looks at the table top first. Wrong end. Flip a chair over and look at the joints — the mortise and tenon corners where the rails meet the legs. Wobble it gently with one hand on the seat and one on the backrest. A little flex is normal in old timber. A joint that moves independently of the rest is not a joint any more, it is a hinge.

Look for screws driven in at odd angles, metal brackets added later, or glue squeezed out along a seam. None of these are automatic disqualifiers — a properly repaired joint can outlast an untouched one — but they tell you the piece has already had a hard life, and that should be reflected in both the price and your expectations.

The slat test, and why your thumbnail beats your eyes

Table tops and chair seats trap water on the underside. Run your hand along the bottom of the slats and press a thumbnail into the timber near a join. Sound teak resists. Rot gives, just slightly, like a bar of soap left in the sink.

Then tap each slat sharply with the handle of a screwdriver. A dry, ringing click means solid timber. A dull thud means the wood is holding water. Check the ends too, where splits begin — a split that runs along the grain is usually cosmetic, a split that runs into the joint is not.

Silver-grey, or actually failing?

Teak goes silver. That is not damage, it is what teak does once the oil has washed out, and it is entirely reversible with a light sand and a couple of coats of oil. Don't let a weathered appearance put you off a good frame.

What you are looking for is a difference in kind rather than colour. Black mould sitting down in the grain, soft patches, checks so deep you can get a fingernail into them, or a patchy, oily surface where someone has slapped on a heavy stain to hide something. If a seller has recently painted a teak table, ask why. The answer is rarely interesting and often expensive.

Metal: rust is not a rumour

Powder-coated aluminium is the good news story of second-hand garden furniture. It doesn't rust, it doesn't rot, and a scratched frame is a cosmetic issue rather than a countdown. Check the welds at the corners and the feet, which sit in wet grass and take the brunt of it. White, chalky corrosion is manageable. Deep pitting is not.

Steel is the other story. Tubular steel chairs and tables rust from the inside out, and by the time bubbles appear in the coating, the wall of the tube has usually thinned. Look at bolt holes, the inside of legs, and anywhere the paint has chipped. If a steel set is showing rust at more than one or two points, walk on.

Rattan: read the weave, not the cushions

Half the rattan sets on the used market are PE, the hard-wearing synthetic that will happily sit outside for a decade. The other half are natural rattan, which will not. Synthetic weave should feel springy; if strands snap when you flex them, the plasticiser has gone and the whole weave is brittle. Natural rattan cracks at the bends and goes slack across the seat.

Assume the cushions are finished. Even good ones hold water, and a replacement set of decent cushions for a four-seater will often cost more than the frame did.

Where the damp hides

Feet caps that have been sitting in soil. Hollow metal legs, which can hold an inch of water for years. Cushion boxes with no drainage. The gap between a table top and its frame. Chairs stacked wet and left stacked. And the underside of anything that has spent five years on a north-facing patio, which in Britain is most things.

What refurbishment actually costs

A tin of teak oil or Danish oil is £15 to £25 and will do a whole set, plus sanding discs and a few hours of your time. Replacement feet caps are a tenner. Cushions are the big one: £60 to £150 per seat is realistic for anything worth sitting on. Professional powder coating runs £60 to £120 per frame, which is only worth it on a frame you genuinely love. Replacement slats, if you can source them, are cheap; if you can't, they become a joinery job.

Add it all up before you commit. If refurbishment, transport and your own weekends come to more than roughly two-thirds of a good new set, you are not bargain hunting — you are volunteering.

The walk-away checklist

• Any joint that moves independently of the frame
• Soft timber under a thumbnail, anywhere
• Rust bleeding through paint on steel at more than one point
• Snapping strands in synthetic weave
• A smell of damp that doesn't fade when you lift the piece clear of the ground
• Hollow legs you can hear water in
• Cushions priced into the deal as though they still have value
• A seller who won't let you turn the furniture upside down

The honest verdict

The best used buys are boring ones: solid teak, aluminium, and well-made synthetic rattan, bought from someone who looked after them and priced them to go. The worst are the ornate, the heavily repaired and the recently painted, sold with a story attached. Take a torch, take a screwdriver, take a friend who will tell you no. And only hire the van once all three have signed off.
