Drag a chair back from the outdoor table and listen for the scrape. That sound is grit and bare chair feet grinding at the most expensive surfaces in the backyard — the deck boards or the alfresco tiles. The cheapest insurance against it is a set of chair leg protectors: the small glides, caps and cups that sit between chair and floor, and that almost nobody thinks about until the damage is done.
This guide covers how the damage happens, which protector suits which surface, and how to fit them so they stay put. The advice applies to nearly everything in our outdoor chairs and benches collection, and to every chair you already own.
Why chair feet damage decks and tiles
An outdoor chair concentrates a person's whole weight into four small contact points, and every time the chair moves those points slide or dig in. On a timber deck a bare metal foot works like a chisel; on tiles it scores fine scratches that slowly dull the glaze.
Grit makes everything worse. A film of sand under a chair foot turns even a smooth glide into sandpaper, which is why coastal and poolside areas mark faster than covered alfrescos. Wet feet cause their own trouble too: bare steel can leave rust rings on pale tiles, and timber legs standing in water wick moisture and leave dark shadows on deck boards.
Chair leg protectors compared: glides, caps and cups
Hardware stores sell chair leg protectors in a handful of families, and they are not interchangeable. Matching the type to the leg shape and the surface is most of the job.
| Protector type | Best for | Watch out for |
|---|---|---|
| Push-in nylon glides | Hollow metal legs; chairs dragged daily | Must match the tube's inside diameter or they work loose |
| Nail-in or screw-on glides | Solid timber legs on decks | Drill a pilot hole first — nails can split slim legs |
| External rubber or PVC caps | Quick fixes, rentals and odd leg shapes | UV hardens them; dark rubber can mark pale tiles |
| Castor cups and load spreaders | Benches and heavy settings on soft decking | They stop sliding entirely, so lift the piece to move it |
| Felt pads | Fully covered, always-dry areas only | Felt soaks up water and holds grit — it fails fast outdoors |
Before the table sends you shopping, tip each chair over. Most new outdoor chairs arrive with basic plastic feet fitted, and often the right move is simply replacing one that has worn through or fallen off. Think about how often each chair moves, too. A bistro-style chair such as the Manly Bistro Chair ($145) is pulled out, angled toward the sun and shuffled back several times a day. Its feet do more sliding in a month than a lounge does in a year. A dining chair like the Eton Chair ($244) lives the same life at the table — which is why our dining chair range is where we would fit glides first.
Matching the protector to the surface
Timber decks — merbau and spotted gum are the common Australian choices — want soft, smooth protectors. Nylon or rubber glides slide without gouging, provided the deck stays swept; grit trapped under any foot will scratch oiled boards. Avoid bare metal completely, and lift rather than drag anything heavy.
Porcelain and ceramic tiles flip the risk: gouging is unlikely, but trapped grit and exposed metal burrs leave scuffs and fine scratches. Hard nylon slides beautifully on tiles, while soft dark rubber can leave black lines on pale porcelain, so test a corner first. Concrete and pavers are the most forgiving surfaces of all — there, the protector mostly saves the chair's feet rather than the floor.
Benches deserve a special mention. A bench sends two or three people's weight through the same four feet a chair uses for one, so wide, load-spreading feet matter most. If you are settling a bench like the Geneva Bench ($844) onto a deck, choose its position once and fit wide glides or castor cups — benches are for settling in, not shuffling about.
Fitting glides and caps so they stay on
Start with clean, dry feet. Tip the chair, scrape off old adhesive, dried grass and salt crust, and let timber legs dry fully before fitting anything over them.
Measure before you buy. External caps need the outside width of the leg; push-in glides need the inside diameter of the tube, and round, square and oval legs each take a different fitting. Take one chair to the hardware store — and buy a spare set, because feet vanish one at a time, never four at once.
Fit PVC and rubber caps on a warm day, or soften them in hot water first; they stretch on more easily and grip tighter as they cool. Folding chairs earn extra attention because they are carried, dropped and leant against walls. A timber folder such as the Teak Folding Chair ($149) is naturally gentle on decks, but bare timber feet left standing in water still wick moisture, so caps remain worth fitting.
Make the check seasonal. The start of spring, when furniture comes back out for its first wash, is the natural moment: one summer of UV is enough to perish soft plastics, and coastal salt air shortens their life further. While each chair is tipped over, glance at the frame too — chalky patches or grey streaks on aluminium legs are a cleaning job, not a hardware one. Our guide to cleaning powder-coated aluminium outdoor furniture covers exactly that.
Chair leg protectors — frequently asked questions
What are the best chair leg protectors for a timber deck?
Soft nylon or rubber glides are the best chair leg protectors for a timber deck, because they slide without gouging the boards. Keep the deck swept so grit cannot get trapped underneath, and avoid bare metal feet and felt entirely.
Do felt chair pads work outdoors?
No — felt pads are an indoor product and fail quickly outside. Felt soaks up rain, holds grit against the floor and peels away once wet, so use it only under a fully covered, always-dry alfresco.
Why do chair legs leave black marks on tiles?
Black marks on tiles usually come from soft dark rubber feet scuffing, or from bare metal showing where a factory foot has worn through. Most scuffs lift with warm soapy water or a melamine sponge, and replacing the offending foot stops them coming back.
How often should you replace chair glides outdoors?
Check them every spring and expect to replace them every year or two. UV hardens and cracks soft plastics, so treat glides as a consumable rather than a fit-and-forget part.
Shop the range
The glides and caps themselves are a cheap hardware-store errand; the seats above them are where we can help. Browse our garden bench collection for pieces built to be positioned once and enjoyed for years, or start smaller with the Teak Backless Bench ($283). We deliver Australia-wide, with free delivery on orders over $100 — so the only trip left is the one for the feet.
