Frequently Asked Questions
Here are some of the most frequently asked questions. If you can't find what you're looking for, please contact us.
What is Polar?
Fleece is a soft and lightweight synthetic fabric made primarily from polyester. It is known for its excellent thermal insulation properties, making it an ideal material for winter clothing such as jackets, blankets, and accessories. Highly comfortable and easy to care for, fleece retains body heat while remaining breathable. Its soft, fluffy texture makes it a popular choice for loungewear and cozy outfits. It is also often chosen for its durability and ability to dry quickly.
What types of fabrics do you offer?
- Cotton : natural, breathable, ideal for sensitive skin.
- Velvet and cotton velvet : soft, warm, perfect for winter.
- Polyester : lightweight, wrinkle-resistant, very easy to wash.
- Burlap : rustic and eco-friendly, perfect for a natural style.
- Coral fleece / sherpa / flannel : the ultimate cocooning materials, for super soft accessories.
- Imitation silk or satin : smooth and shiny effect, pleasant for the skin and hair.
How to wash textile products?
Each product sheet specifies specific recommendations, but here are the general rules:
- Cotton/polyester fabrics : machine wash at 30-40°C, gentle spin. Air drying recommended.
- Velvet, flannel, sherpa : delicate wash, dry flat or at low temperature.
- Products with filling or stuffing (cushions, poufs) : prefer hand washing or dry cleaning.
- Rugs and throws made from natural materials : dry clean or clean with a damp cloth to avoid damaging the material.
Why are some products made of polyester and not cotton?
Polyester offers significant advantages:
- It does not wrinkle , which makes it easy to maintain.
- It is more resistant over time and less prone to discoloration .
- It allows for texture effects (imitation silk, sherpa, etc.) that are often impossible to achieve with cotton alone.
We select quality polyester fabrics to ensure comfort and durability.
Do you use natural materials?
Yes, whenever possible. We offer:
- Hand-woven jute rugs
- Rattan or cotton rope baskets
- Products made from linen, cotton or mixed plant fibers
We ensure a good balance between natural materials , ease of maintenance , and affordable prices .
Are your covers, throws, and cushions removable?
It depends on the models:
- Decorative cushions : some have removable covers, others do not (check the description).
- Poufs and seat cushions : most often with zipper.
- Blankets and covers : not removable, but easy to machine wash.
How to maintain carpets?
Our rugs can be:
- Vacuumed regularly
- Tapped or shaken outside
- Clean with warm water and mild soap (avoid soaking)
- Some models support steam or machine cleaning (delicate cycle) .
👉 Tip: To remove wrinkles, unroll the rug upside down for a few days or apply a weight. A steam iron (on low heat) can also help.
