Wool felt vs. Polyester felt – the difference
Felt is not just felt: Polyester needle felt is the proven standard, wool felt is the premium natural fibre class. How to recognise quality and when the surcharge is worthwhile.
Polyester needle felt: the proven standard
With needle felt, polyester fibres are mechanically needled into a dense, dimensionally stable fleece. The result is a uniform, hard-wearing material with a very good price-performance ratio – the right choice for most furniture in the home.
Wool felt: the natural fibre premium class
Wool felt is felted from pure virgin wool. The natural fibre is denser and more elastic: it absorbs impact, runs even quieter and retains its shape even under continuous load. Added to this is the sustainability of the renewable raw material – and a haptic quality that you can see and feel.
How to recognise quality
- Density: High-quality felt feels firm and can hardly be pressed in – loose felt quickly flattens out.
- Uniformity: The surface is even, without thin spots or loose fibres.
- Adhesive: A strong, solvent-free acrylic adhesive is part of the quality picture – the best felt is useless if it falls off.
When wool felt is worthwhile
Wherever smooth running and durability make the difference: under chairs used daily on delicate floors, in bedrooms and living rooms, with high-quality furniture where every detail should match. For rarely moved furniture, polyester needle felt is perfectly sufficient.
