Felt Glides vs. Teflon Glides — Which Furniture Glide for Which Floor?

A felt glide protects delicate, smooth hard floors such as parquet from scratches, whilst a Teflon glide enables the effortless movement of furniture across soft or high-friction surfaces like carpets and tiles thanks to minimal resistance.

Choosing the correct glide underneath a piece of furniture is a technical necessity to dissipate kinetic energy during movement without damaging the flooring or compromising the structural integrity of the piece. Just as the tyres of a vehicle must be precisely matched to the road surface, the furniture glide defines the contact area between the furniture and the floor. The wrong glide results in severe wear, scratches, or snapped furniture legs.

This technical guide analyses the material properties, friction resistance, and correct installation methods of felt and Teflon glides for professional furniture construction and proper fitting.

What are Felt Glides?

A felt glide consists of compressed fibres, usually manufactured as needle felt or from synthetic blended fabrics. The material thickness typically varies between 3 mm and 5 mm. The primary function of felt is to provide soft cushioning between the hard edge of the furniture and the floor.

Technically speaking, felt has the property of absorbing micro-impacts and capturing fine dust or sand particles within its fibrous structure. This prevents hard dirt particles from acting like sandpaper when dragged across the floor. Felt glides are available in various configurations, from self-adhesive discs to securely screwable variants with plastic or metal bases. Matching options can be found in the felt glides category.

What are Teflon Glides?

A Teflon glide uses PTFE (polytetrafluoroethylene) as its sliding layer. This high-performance plastic is characterised by an extremely low coefficient of friction (approximately 0.04 to 0.10, comparable to wet ice on wet ice).

In contrast to felt, the surface of PTFE is completely non-porous, smooth, and hard. The material absorbs neither moisture nor dirt particles. Teflon glides usually consist of a shock-absorbing base material (such as natural rubber or synthetic rubber) to which the PTFE layer is bonded or fused. The total thickness is often between 5 mm and 7 mm. Due to the smooth surface, the physical effort required to move heavy furniture is drastically reduced, as the static friction is virtually identical to the dynamic friction.

Technical Differences in Detail

To make the right choice for an installation project, the physical differences between the two materials must be examined:

• Friction resistance: PTFE offers significantly lower resistance than felt. On textile surfaces, felt binds, whilst Teflon glides effortlessly.
• Particle absorption: Felt encapsulates dirt particles, protecting the floor. Teflon pushes particles ahead of itself. If coarse dirt lies on a smooth floor, a Teflon glide can drag it across the surface, causing scratches.
• Pressure resistance and deformation: Felt compresses over time under the static load of heavy cabinets. A 5 mm thick felt pad can compress down to 2 mm after one year. PTFE retains its dimensional stability even under high point loads.
• Moisture resistance: Felt absorbs mop water. If moisture penetrates the felt, the fibres harden as they dry, ruining their sliding properties. PTFE is entirely water-repellent.
• Shear forces: On floors with deep grout joints (such as rustic tiles), high shear forces act on the glide during movement. Felt frays or tears away on sharp tile edges. Teflon glides smoothly across the joints.

Which Glide for Which Floor? (Areas of Application)

The selection of the glide depends strictly on the nature of the flooring.

Applications for Felt Glides

Felt is the material of choice for delicate, smooth hard floors.

• Parquet and solid wood floorboards: The soft structure prevents indentation in the wood.
• Laminate: Protects the thin melamine resin layer from micro-scratches.
• Smooth tiles / marble: Prevents scuffs and dampens scraping noises when moving chairs.

Applications for Teflon Glides

Teflon is used where felt fails due to excessive friction or surface texture.

• Carpets and fitted carpeting: PTFE glides over textile fibres without catching.
• Rough tiles and stone floors: The hard surface withstands abrasion from coarse ceramics and deep joints.
• Resilient floors (vinyl, PVC, linoleum): On these high-drag surfaces, felt creates too much resistance. Teflon minimises tensile and shear forces that could otherwise stretch or damage resilient coverings.

Installation Methods: Stick, Screw, or Nail?

Regardless of the material (felt or Teflon), the mounting method determines the longevity of the connection between the glide and the furniture feet.

1. Self-adhesive glides: Primarily suitable for static furniture (such as dressers and display cabinets) that is moved rarely. The adhesive often fails after only a few weeks under regular shear loads (such as on dining chairs).
2. Nail-on glides: Driven into the end grain of the furniture leg using an integrated steel nail. Suitable for solid wood. With chipboard, there is a risk of splitting.
3. Screw-on glides: The technically superior solution for dynamically loaded furniture. The glide is fixed with a countersunk screw.

Professional Installation of a Screw-on Glide:

• Mark the centre point of the furniture leg.
• Pre-drill with a wood drill bit (typically 2 mm or 2.5 mm) to prevent the wood from splitting.
• Position the glide and drive in the screw (usually PZ or TX drive). The screw head must be set deep within the carrier material so that it does not scratch the floor when the glide material wears down. Suitable fixings for such installations can be found under wood screws and furniture screws.

For furniture with metal legs — such as those found under square metal furniture feet or chrome furniture feet — special insert plugs or clamp-on glides pressed into hollow steel tubes are frequently utilised. Height-adjustable systems, such as adjustable furniture feet, also often feature an integrated plastic or Teflon sliding surface straight from the factory.

Structural Loads and Force Dynamics During Movement

When a heavy wardrobe is shifted, enormous leverage forces act on the carcass. If the glide binds (such as felt on carpet), the force transfers directly to the connecting fittings of the furniture. This can cause cam-lock fittings to tear out or wooden dowels to snap. A low-friction Teflon glide not only protects the floor, but also relieves stress on the furniture connectors inside the carcass.

FAQ – Frequently Asked Questions About Furniture Glides

Can felt glides be used on carpet? No. The fibrous texture of felt catches in carpet fibres, causing extremely high friction resistance. The furniture becomes difficult to move, and shear forces will usually rip the glide off the furniture leg in short order.

How often should furniture glides be replaced? This depends on dynamic usage. On heavily used dining chairs over rough tiles, the sliding layer should be inspected every 6 to 12 months. If the material is worn down to the plastic carrier or screw head, the glide must be replaced immediately to prevent deep scratches on the floor.

Which glide is best for heavy wardrobes and cabinets? For the initial positioning of a heavy wardrobe on hard or soft floors, Teflon glides are optimal as they make pushing significantly easier. Once the wardrobe is in its final position, the type of glide is secondary, provided it withstands the static load without indenting the floor.

What should be done with angled furniture legs? If chair legs are angled relative to the floor (such as splayed retro legs), a standard flat glide will only rest on its outer edge. In this case, swivel glides must be used. These feature a ball joint that compensates for the angle of inclination, ensuring the sliding surface rests completely flat against the floor.
