Silicone vs Rubber vs Felt: Choosing the Right Pad Material

Walk down the floor-protection aisle and you will meet the same three materials again and again: silicone, rubber, and felt. They look interchangeable, but they behave very differently, and the most common furniture-protection mistake is using one where another belongs. Here is how to tell them apart and choose well.

The one question that decides it

Before comparing materials, answer a single question: do you want the item to grip or to glide? A bookcase that must not creep, and a dining chair that must slide out easily, want opposite things. Grip and glide are the two ends of the friction scale, and the three materials line up along it — so the answer to that one question does most of the choosing for you.

Felt: made to glide

Felt pads are dense fabric discs with a low coefficient of friction. Their whole purpose is to let furniture slide smoothly and quietly over hard floors without scratching. That makes them ideal for anything you move regularly — dining chairs, stools, light tables, ottomans.

Their strengths and limits follow directly from that low friction:

• Best for: chairs and movable furniture on hardwood, laminate, and tile.
• Weakness: they let furniture slide, which is a problem if you wanted it to stay put. They also wear down, trap grit, and can peel if not stuck to a clean surface.

Never use felt where you need grip: a felt-footed shelf on a smooth floor is an accident waiting to happen. See our guide to stopping furniture sliding on hard floors for what to reach for instead when a piece needs to stay put.

Rubber: the all-rounder that grips

Rubber is the versatile middle of the range. It has a high coefficient of friction, so it grips; it is elastic, so it cushions shock and absorbs vibration; and it is tough, so it carries load and wears slowly. That combination makes rubber the default for feet, bumpers, grip dots, and non-slip pads.

• Best for: keeping things in place, cushioning impacts, carrying weight, damping vibration — appliances, cabinets, workbenches, electronics.
• Weakness: that same grip stops furniture sliding, so it is wrong for chairs you move often. Some cheaper rubbers can also mark light-coloured vinyl, so choose non-marking grades on soft floors.

If you are unsure and the item mostly sits still, rubber is the safe default. Its hardness, measured in durometer, lets you tune it from soft-and-grippy to firm-and-load-bearing; our durometer guide explains what those numbers mean, and the durometer & material reference lays out where rubber, felt-adjacent soft compounds, and hard plastics each sit on the same scale.

How hardness maps onto these three materials

It’s worth being specific about where each material actually sits on the durometer scale, since “rubber” on its own covers an enormous range. Feet and bumpers described simply as rubber are usually formulated somewhere in the medium 50–70 Shore A band — firm enough to carry a load, soft enough to grip and cushion. Silicone parts for furniture use typically run softer, often in the 30–60 Shore A range, which is part of why silicone feet can feel noticeably squishier by comparison at the same nominal size, even though softness itself isn’t what makes silicone special — its heat and weathering resistance are. Felt isn’t measured on the Shore scale at all, because it isn’t an elastomer in the same sense; its performance comes from fibre density and surface texture rather than indentation hardness, which is exactly why a durometer reading is meaningless for it and grip/glide is the only comparison that applies.

Silicone: rubber’s specialist cousin

Silicone is a rubber-like material with a few standout properties. It grips well, like rubber, but it also handles heat and cold far better, resists ageing and sunlight, stays flexible over time, and — importantly — is generally non-marking. That makes it the choice for demanding or delicate spots.

• Best for: hot or cold environments, outdoor use, contact with light-coloured or sensitive surfaces, and anywhere longevity matters — oven-adjacent trivets, appliance feet, delicate finishes.
• Weakness: usually costs more than plain rubber, and can be softer, so it is not always the best pick for heavy static loads.

Cost and lifespan, honestly compared

Felt is the cheapest of the three by a wide margin and the shortest-lived under real use — a pad that’s dragged across a floor daily wears down in visible, physical fashion, thinning until it stops protecting anything and needs replacing on a schedule measured in months for a busy chair. Rubber costs more per pad but lasts far longer under static or cushioning duty, typically only failing when the adhesive lets go or the compound eventually hardens with age rather than through mechanical wear. Silicone sits at the top of the price range but earns it in the specific conditions it’s built for: a plain rubber foot near real heat or strong sun will degrade far faster than a silicone one in the same spot, so the higher unit cost can be the cheaper choice over the item’s life if the environment genuinely calls for it. Buying silicone for a cool, dry living room, on the other hand, is paying for weather resistance you’ll never use.

A quick comparison

• Want it to slide? Felt.
• Want it to stay put, carry weight, or cushion a knock? Rubber.
• Same as rubber, but hot, cold, outdoors, or against a delicate finish? Silicone.

Mixing materials in one home

You rarely settle on just one. A typical home uses all three exactly where each belongs: felt under the dining chairs so they slide out quietly, rubber non-slip pads under the sofa and the freestanding bookcase so they stay put, silicone feet under the countertop appliances near the hob where it gets hot. Thinking in terms of the job each piece does, rather than buying one material for the whole house, is what gets every item the pad it actually needs.

When the surface itself decides for you

Sometimes the choice isn’t really about grip versus glide at all, because the surface underneath rules one material out before friction even enters the conversation. A hot surface near a stovetop or a radiator will soften and eventually degrade a plain rubber compound faster than it will silicone, regardless of which one grips better on paper. A delicate painted or lacquered finish can be marked by a cheap rubber’s migrating additives in a way felt or a non-marking silicone won’t risk. And a very low-friction plastic surface can defeat a standard adhesive backing on any of the three materials, which is a bonding problem rather than a material-choice problem — see our guide to why adhesive pads fall off for that side of it.

Telling them apart by touch

If a pad is unlabelled or you’re trying to identify what’s already fitted under a piece of furniture, a quick touch test gets you most of the way there. Felt has an obvious fibrous, fabric-like texture and doesn’t bounce back with any elastic snap when pinched — it just compresses. Rubber and silicone both feel smooth and springy, but rubber typically has a slight tackiness and a more “rubbery” smell, while silicone tends to feel a touch more slippery and rubbery-cool to the touch, with less odour, and often flexes back a fraction faster after being pinched. Neither of those last two tells is fully reliable on its own, since formulations vary, but combined with context — is it near heat, does it look worn in a way that suggests years of outdoor exposure — you can usually make a confident call without cutting a sample off to test.

Five common scenarios, answered directly

• Dining chairs on a wood floor: felt, so they slide out and back without scratching or fighting the floor.
• A freestanding bookcase that must not walk away from the wall: rubber non-slip pads, sized generously enough to carry the loaded weight.
• Feet on a toaster or kettle that sits near a hot hob: silicone, for the heat tolerance alone.
• A glass-top coffee table’s corner bumpers: either rubber or silicone works for grip on glass; pick silicone if the bumpers will see direct sun through a window.
• An outdoor bench or planter foot: silicone or a purpose-made outdoor rubber compound, never plain indoor felt or a basic rubber blend that isn’t rated for UV and weather.

Avoiding the common mismatch

Almost every disappointment with floor pads is a material mismatch: felt where grip was needed, or grippy rubber under a chair that now judders instead of sliding. Start from grip-or-glide, pick felt for glide and rubber for grip, and upgrade to silicone when heat, weather, or a delicate surface raises the stakes. Get that first decision right and the material almost chooses itself, and the size and spacing of whatever pad you land on is a separate question our other guides — on sizing a foot to its load and on spacing grip dots across an area — can help you answer next.
