What are the challenges of outdoor furniture fillings?

When it comes to choosing fillings for your outdoor furniture, it is important to consider any practical challenges you may face.

  • Weather resistance requirements: The unpredictability of British weather is a challenge that must be factored in when selecting fillings for outdoor furniture. From heavy rain to mini heatwaves, it is vital that fillings possess exceptional weather resistance to ensure the longevity of your outdoor furniture.
  • Durability needs: Your outdoor furniture will be subjected to more rigorous use in comparison to indoor furniture. That’s why it is important that your filing materials for outdoor furniture can withstand constant compression and retain their shape and support. A filling material that quickly loses its loft will not only compromise comfort but also the overall appearance of your furniture.
  • Comfort expectations: The comfort of your fillings mustn’t be compromised. Your filling materials should be the correct balance of support and plushness, allowing for a relaxed seating experience.
  • Maintenance considerations: Different fillings require differing levels of maintenance to ensure they provide both comfort and longevity. Opting for low-maintenance, easy-to-clean fillings can save you valuable time and effort, allowing you to focus on enjoying your outdoor space.

Think Group’s unique fibres and fillings product range

At Think Group, we offer a range of high-quality products that are perfect for your outdoor manufacturing needs:

Hollow Conjugate Fibres

Hollow Conjugate Polyester Fibres are superior fibres known for their enhanced resilience and loft, thanks to their unique three-dimensional crimp. This makes them an ideal choice for filling your outdoor furniture cushions.

Hollow Fibres

Hollow Polyester Fibre is a type of polyester staple fibre that is characterised by its hollow structure, offering both comfort and durability. This enhances insulation, providing excellent thermal retention and making it a popular choice for filling materials in outdoor cushions.

Springbond Ultraflex

Ultraflex is our high-performance, chemical-free alternative to PU foam. Using next generation performance fibres, carefully engineered in a sweeping ‘s’ shape structure, Ultraflex provides unrivalled rebound, comfort & long-lasting performance, typically outperforming commensurate foams in hardness loss testing. Ultraflex is also less insulating than foam and five times more breathable than PU foam. This makes it a very comfortable and moisture resistant cushion filling material.

As Ultraflex is hydrophobic and free draining, it means that water will not be absorbed, making it suitable for the outdoors. All you have to do is simply stand the seat cushions upright, and the water will drain straight out.

Our commitment to sustainability

Our polyester fibres are made from repurposed materials including plastic bottles, and to date, we have diverted over 65 million bottles from landfill and oceans, highlighting our commitment to sustainable manufacturing

Recycled polyester has a low environmental impact due to reduced plastic waste and energy consumption during the manufacturing process. 

In comparison, virgin polyester is produced from petroleum-based raw materials, which requires more resources, and therefore has a significantly higher carbon footprint. While virgin polyester remains a popular choice for performance and comfort, recycled polyester offers a more environmentally responsible alternative by reducing plastic waste and energy use in production.

“We pioneer innovative and sustainable solutions that

inspire our customers and their customers to think

differently about textile fibres, applications and their impact on the world”
