Felt Glides vs. Plastic Glides vs. Teflon Glides: Which Floor Protection?

Felt glides are ideal for scratch-sensitive wooden floors, plastic glides for uneven tiles and carpets, whilst Teflon glides make heavy furniture effortless to move across hard floors thanks to minimal friction.

Choosing the correct floor protection hardware beneath furniture determines whether flooring remains intact over time or suffers from grooves and scratches. A chair leg on untreated parquet acts like fine sandpaper under load. Anyone moving chairs, tables, or heavy cabinets must decouple the contact point between the furniture piece and the floor covering using glides. The materials felt, plastic, and Teflon feature completely different physical properties.

This article breaks down the technical differences between these three glide types and demonstrates which material is engineered for which flooring and application.

What Are Felt Glides?

Felt glides consist of compressed fibres. Typically, this involves synthetic needle felt or wool felt compacted under heat and pressure. The structure of felt is soft, flexible, and extremely gentle on smooth surfaces.

Advantages:

• Noise reduction: Felt heavily absorbs sound when shifting chairs on hard floors.
• Scratch protection: The soft fibre structure prevents hard wood or metal on furniture legs from contacting the floor.
• Contour adaptation: Felt yields slightly under pressure, compensating for microscopic irregularities in the floor.

Disadvantages:

• Wear: Felt wears away through constant movement. Under heavily used chairs, the glides must be replaced regularly.
• Dirt accumulation: Dust, pet hair, and tiny grains of sand can get caught in the felt. If hard particles become embedded, the glide itself can present a scratching risk.
• Moisture: Felt absorbs liquid. When mopping the floor, damp felt can swell or discolour light-coloured floors.

For a discreet look, glides are selected to match furniture colours or flooring, such as black felt glides for dark chair legs. The shape depends on the leg profile; round felt glides are the standard choice for classic tubular frames or turned wooden legs.

What Are Plastic Glides?

Plastic glides are predominantly manufactured from polyamide, polyethylene, or other rigid thermoplastics. They form a smooth, solid barrier between furniture and the floor. In furniture making, they are frequently combined with a thread as height-adjustable plastic furniture feet to level out uneven flooring.

Advantages:

• Hardness rating: Plastic wears down considerably slower than felt on rough surfaces.
• Moisture resistance: The material does not absorb water, making it suitable for damp rooms, kitchens, or outdoor use.
• Gliding ability on textiles: Hard plastic slides smoothly across carpeted floors because it does not snag in carpet fibres.

Disadvantages:

• Scratch risk on wood: On soft parquet or cork, hard plastic can leave indentations or cause scratches, especially if dirt particles become trapped underneath the glide.
• Noise: Moving furniture with plastic glides over tiles or laminate generates loud scraping noises.

What Are Teflon Glides?

Teflon glides are made of polytetrafluoroethylene (shortened to PTFE). This high-performance polymer features an extremely low coefficient of friction. It is the same material used for non-stick pan coatings. Frequently, the glide consists of a damping core (e.g. rubber) and a smooth PTFE sliding surface.

Advantages:

• Minimal resistance: Even heavy solid wood cabinets or large sofas can be slid across the floor by a single person using Teflon glides.
• Shock absorption: The integrated rubber core dampens vibrations and noise.
• Hygienic: Dust and dirt barely adhere to the extremely smooth PTFE surface.

Disadvantages:

• Pressure marks: Under very heavy furniture on soft flooring (e.g. thick vinyl), the contact area is sometimes insufficient to prevent pressure marks, as the material does not yield as much as thick felt.

Direct Comparison of Differences

To evaluate technical suitability, glides should be distinguished by three main criteria:

• Friction on hard floors: PTFE offers the lowest resistance. Felt provides slight braking but glides softly. Plastic resists on hard floors and tends to judder.
• Friction on soft floors (carpet): Plastic and PTFE glide exceptionally well over textile fibres. Felt is unsuitable here, as it catches on carpet fibres and tears off.
• Maintenance interval: Felt requires inspection and regular replacement. PTFE and plastic often last for years without significant wear.

Selecting the Correct Mounting Method

Alongside the material, the fixing method used on the furniture piece is essential for stability. A detached glide provides no protection.

1. Self-adhesive glides: The fastest method. The adhesive surface is pressed onto a cleaned, grease-free furniture leg. Suitable for static furniture such as chests of drawers or wardrobes. Under dining chairs, adhesive glides often detach after a few weeks due to continuous shear forces.
2. Nail-in glides: The glide is connected to a steel nail driven into the wooden leg. Provides high stability against lateral forces.
3. Screw-in glides: The most secure fitting. The glide is fixed into the furniture leg with a wood screw (usually PZ or TX). Even under heavy loads, the glide will not tear off.
4. Clip-on glides / inserts: Designed for tubular steel chairs (cantilever chairs). They are either pushed into the open tube or clipped around the frame.

Mounting tip for screw-in and nail-in glides: For solid wood legs, always pre-drill a pilot hole (e.g. using a 2 mm wood drill bit). Without pre-drilling, the chair leg may split when driving in the nail or tightening the screw.

Which Glide Should Be Selected for Each Scenario?

The choice depends primarily on the floor covering and how frequently the furniture item is moved.

Scenario 1: Dining Chairs on Parquet or Laminate

Here, felt is the preferred material. If you have grey dining chairs or white wooden dining chairs on oiled oak parquet, felt protects the wooden surface from scratches and muffles sliding noises. Opt for screw-in glides, as adhesive options cannot withstand constant movement.

Scenario 2: Heavy Furniture on Hard Floors

For a heavy sideboard or a solid wardrobe that needs to be moved periodically for cleaning, Teflon glides (PTFE) are ideal. The low frictional resistance prevents back strain when moving heavy loads and stops furniture from rattling across the floor.

Scenario 3: Furniture on Carpeting

On short-pile and deep-pile carpets, plastic is the best solution. The hard, rounded surface glides over textile fibres without resistance. Felt would fray immediately from the friction.

Scenario 4: Furniture on Rough Tiles or Outdoors

On tiled floors with deep grout lines or rough natural stone, felt tears off rapidly. PTFE can be scratched by sharp edges. Robust plastic glides excel here. They are unaffected by moisture during cleaning and endure the mechanical stress of wide joints.

Frequently Asked Questions (FAQ)

How often should felt glides be replaced?

This depends on usage. For chairs used daily on hard floors, the felt should be inspected every 6 to 12 months. Once the felt is compressed to under 1 mm or dirt has embedded into it, the glide must be replaced to protect the flooring.

Can plastic glides scratch parquet?

Yes. Plastic is harder than many wood species. When furniture is moved, the plastic itself can cause grooves in lacquer or oil finishes. It is even more dangerous if hard sand particles get caught beneath the plastic glide and drag across the parquet.

What is the difference between PTFE and Teflon?

There is no chemical difference. Polytetrafluoroethylene (PTFE) is the chemical term for the polymer. Teflon is simply a registered trademark of the Chemours company (formerly DuPont) for this exact material.

Which glides are suitable for vinyl flooring (LVT)?

Vinyl is an elastic, softer hard floor. Felt glides work well here to prevent scratches. For heavy furniture that is moved frequently, Teflon glides are preferable, as they ease shifting without leaving marks on the vinyl.

How do I remove old adhesive residue from chair legs?

Before fitting new glides, the wooden leg must be clean. Old adhesive residue from self-adhesive glides can be softened using rubbing alcohol (isopropanol) or a dedicated label remover, then scraped away with a plastic scraper.
