Felt Glides or Teflon Glides? The Best Floor Protection for Parquet and Laminate

A felt glide protects delicate hard floors such as parquet from scratches using soft needle felt, whilst a Teflon glide made from polytetrafluoroethylene (PTFE) minimises frictional resistance on textile or matt surfaces.

Choosing the right floor protection under furniture is a technical decision that depends on the properties of the floor covering, the weight of the furniture piece, and dynamic loading. The wrong glide results in irreversible scratches in the wood, worn chair legs, or jammed furniture. This guide breaks down the mechanical characteristics, fixing methods, and specific application areas of furniture glides in detail.

Types and Materials: Felt vs Teflon

The industry provides different materials to control friction between a piece of furniture and the floor. The two dominant materials are felt and PTFE, which exhibit completely opposing physical properties.

The Felt Glide

Felt is a textile fabric, typically pressed from synthetic fibres or sheep's wool. In furniture manufacturing, high-density needle felt is predominantly used. This is characterised by high abrasion resistance.

The primary function of felt is cushioning. Like a shock absorber on a vehicle chassis, thick felt absorbs microscopic unevenness in the floor and prevents hard materials from meeting directly. Felt absorbs tiny dirt particles such as grains of sand into its structure instead of dragging them across the floor like sandpaper. Standard commercial material thicknesses range between 3 mm and 5 mm.

The Teflon Glide

Teflon is the well-known trade name for polytetrafluoroethylene (PTFE). This high-performance plastic has an extremely low coefficient of friction. PTFE glides are hard, smooth, and dimensionally stable.

Unlike felt, they do not cushion, but instead allow the furniture to glide across the substrate. They do not absorb moisture or dirt. This makes them the standard technical solution for heavy furniture on soft or textured floors, where felt would drag bluntly or fray.

Overview of Fixing Methods

The material of the gliding surface is only one part of the construction. The method of connection to the furniture piece determines durability, particularly for dynamically loaded furniture such as dining chairs.

Self-Adhesive Glides

The rear of the glide is coated with an industrial adhesive.

• Advantage: Fast, tool-free installation.
• Disadvantage: Low resistance to lateral shear forces.
• Application area: Static furniture such as wardrobes, chests of drawers, vases, or light side tables.

Nail-in Glides

The glide is firmly bonded to a steel nail (usually 1.5 mm to 2.5 mm in diameter). The nail is driven into the end grain of the furniture leg.

• Advantage: Secure fit, withstands light to moderate shear forces.
• Disadvantage: Risk of splitting thin wooden legs; difficult to remove.
• Application area: Wooden chairs, light to medium-weight tables.

Screw-in Glides

The most stable mechanical connection. The glide features a countersunk hole through which a screw is driven into the furniture leg.

• Advantage: Maximum pull-out strength, easy to replace.
• Disadvantage: Requires precise pre-drilling and the use of tools.
• Application area: Heavy dining tables, heavily used chairs in hospitality, solid wood furniture.

Insert Plugs and Caps

For furniture with tubular steel legs, glides are used either as tube inserts pressed into the hollow tube or as caps fitted externally over the tube. Here, the exact internal or external diameter of the tube (e.g. 20 mm or 25 mm) is the decisive dimension.

How to Choose: Criteria for the Right Floor Protection

Specifying the right glide requires analysing three factors: floor surface, type of load, and the geometry of the furniture leg.

1. Matching the Floor Covering

The fundamental rule of friction mechanics is: soft glide for hard floors, hard glide for soft floors.

• Parquet, laminate, wooden floorboards: Felt glides are mandatory. The soft material protects the sealant or oil finish of the timber. PTFE would cause scratches here if grains of sand become trapped.
• Tiles and natural stone: Thick felt glides or Teflon glides can be used here. For deep grout lines, PTFE is often advantageous, as felt quickly frays on sharp tile edges.
• Carpeted flooring: Teflon glides are mandatory. Felt causes strong drag on textiles, making furniture difficult to move and causing the felt to tear off. PTFE glides effortlessly over fibres.
• Vinyl and linoleum: Both materials are possible. On soft vinyl, felt is often preferred to prevent pressure marks during movement.

2. Weight and Dynamic Load

A distinction is made between static loading (furniture remains permanently in place) and dynamic loading (furniture is pulled, pushed, tilted).

A heavy wardrobe exerts a high static point load on the floor. Self-adhesive felt pads are sufficient here, as the furniture piece is not moved. The pads simply serve to protect the floor during initial positioning.

A dining chair, on the other hand, is subjected to extreme dynamic forces. A person sits on it, perhaps tilts it, and the chair is pulled towards the table and pushed back multiple times daily. These lateral shear forces rip self-adhesive glides off within days. Therefore, screw-in or nail-in glides are essential for chairs.

3. Geometry and Material of the Furniture Leg

The shape of the contact area dictates the shape of the glide.

• Round legs: Require round glides. The diameter of the glide should be approximately 1 mm to 2 mm smaller than the diameter of the furniture leg to prevent overhang and catching on edges.
• Square legs: Require square glides. Especially with square metal frames, common in industrial designs, it is worth looking at suitable square metal furniture legs, which often come fitted with integrated plastic or felt protectors.
• Angled legs: A particular technical challenge. If a chair leg stands at an angle (e.g. 15°) to the floor, a standard flat glide will only rest on its edge. This results in extreme point loading that damages the floor and wears out the glide immediately. In this case, swivel glides must be used. These feature a ball joint that compensates for the angle, ensuring that the felt or Teflon surface rests completely flat on the floor.

Practical Applications

Floor Protection for Tables

Tables carry significant self-weight. For wooden tables, screw-in glides with thick felt (5 mm) should be used. If the table features heavy metal runner bases, wide, rectangular felt strips can be glued on. As tables are rarely moved, the adhesive holds adequately here.

Floor Protection for Chairs

As analysed, a screw fitting is the gold standard here. Use suitable wood screws and furniture screws with a flat head if the glide only has a hole but no integrated screw head. The screw head must be deeply countersunk within the glide so that it does not scratch the floor as the felt wears down.

Alternatives for Mobile Furniture

If a piece of furniture needs to be moved regularly across parquet (e.g. a mobile pedestal or serving trolley), glides are the wrong choice. Furniture castors should be used instead. For hard floors like parquet, castors with soft polyurethane tread (often contrasting in colour) must be selected. Hard plastic castors would damage the wood. When replacing fixed furniture legs with castors, ensure the correct thread size (typically M8 or M10) for the mounting plate.

Installation and Technique: Fitting Glides Correctly

Correct installation determines the durability of floor protection. Below are the technical procedures for the most common fixing methods.

Required Tools

• Cordless screwdriver
• Wood drill bit (typically 1.5 mm to 2.5 mm)
• Rubber mallet
• Sandpaper (120 grit)
• Cleaning agent (isopropanol or methylated spirits)

Installing Self-Adhesive Glides

1. Preparation: The underside of the furniture leg must be completely free of dust and grease. Sand rough timber areas flat using sandpaper.
2. Cleaning: Wipe the surface with isopropanol and allow it to evaporate completely.
3. Application: Peel off the backing film, position the glide centrally, and press firmly for at least 30 seconds. Final adhesive strength is usually reached only after 24 hours; do not move the furniture during this time.

Installing Screw-in and Nail-in Glides into Timber

1. Locate centre: Mark the centre of the furniture leg.
2. Pre-drilling: This step is mandatory in hardwoods (oak, beech) to prevent the leg from splitting. The drill diameter should be slightly smaller than the screw or nail diameter (e.g. a 2 mm drill bit for a 3 mm screw). The drill depth matches the length of the shaft.
3. Fixing: Drive the screw flush using a cordless screwdriver (on a low torque setting). For nail-in glides, drive the pin straight into the pilot hole with gentle taps from a rubber mallet. Do not use a steel hammer, as this will shatter the plastic base of the glide.

Readjustment on Uneven Floors

If a cupboard wobbles despite glides being fitted, it is usually due to an uneven floor. This is where flat felt glides reach their limit. The technical solution is adjustable furniture legs. These feature a thread that allows height levelling to the exact millimetre. Thin felt pads can then be adhered beneath these adjustable plastic or metal bases.

Maintenance and Wear

Floor protectors are wear components. Under load, a felt glide compresses over time and becomes thinner. In addition, dust, hair, and fine sand particles collect within the fibre structure. When the felt hardens and discolours dark, it loses its protective function and becomes abrasive.

Check the glides under heavily used chairs every six months. Screw-in glides can be replaced in seconds simply by loosening the screw and fitting a new component.

FAQ – Frequently Asked Technical Questions About Furniture Glides

Why do self-adhesive felt glides constantly fall off my chairs? Chairs are subjected to severe lateral shear forces when moved back and forth. The adhesive gives way under this dynamic load, causing the glide to shift and fall off. For chairs, screwed or nailed glides must be used without exception.

Which glide is right for angled chair legs? On angled legs, a rigid glide only contacts the floor on its edge. This leads to extreme point loading and ruins the floor. You need swivel glides. These feature a ball joint that adapts to the angle of the chair leg, ensuring the felt surface rests entirely flat on the floor.

Can I use Teflon glides on parquet flooring? Technically it is possible, as PTFE glides very smoothly. However, it is not recommended. If a hard grain of sand gets between the Teflon glide and the parquet, it will not be absorbed like it would by felt; instead, it is pressed into the wood, carving deep scratches into the finish. For parquet, felt is always the safer choice.

How thick should a felt glide be for heavy furniture? For heavy tables, beds, or solid wood cabinets, the felt thickness should be at least 5 mm. Thinner felts (e.g. 2 mm or 3 mm) compress too quickly under heavy weight and lose their cushioning properties.

What do I do for chairs with tubular steel legs? Do not drill into hollow steel tubes. Insert glides are used here, which are pressed into the tube via ribbed fins. Alternatively, caps can be fitted externally over the tube. Accurately measuring the internal or external tube diameter in millimetres is crucial.

How do I remove old, stubborn adhesive residue from furniture legs? When switching from self-adhesive to screw-in glides, the timber must be clean. Mechanically remove bulk residue with a scraper. Sticky residues can be softened and wiped away using isopropanol, white spirit, or a dedicated label remover. Lightly abrade the surface with sandpaper afterwards.

Is there an alternative to glides if I need to move furniture often? If pieces of furniture are primarily to be rolled rather than slid, fitting furniture castors is the professional solution. For parquet, always ensure castors have a soft polyurethane tyre.
