Sustainable materials

The journey to develop a sustainable and ethical Everpia starts with the selection of materials. Throughout the design, production, and disposal lifecycle, we prioritize materials having low impacts on the environment and society, from every thread in the Everon blanket to every spring coil in the KingKoil spring mattress. We collaborate with the supply chain to promote the use of certified eco-friendly materials and achieve our goal of increasing the use of sustainable materials over our main materials: fibers and fabrics.

Recycle fibers

With the main material to produce padding being polyester fiber, we move towards replacing the use of virgin fibers with recycled fibers. This is a type of fiber that is recycled from PET plastic bottles after use. The amount of recycled fiber we use every year for the production of padding is equivalent to recycling approximately 200 million of 500 ml plastic bottles.

Traditional fiber is gradually being replaced by Sorona fiber, a sustainable fiber whose main substance is Bio-PDO - a resin obtained through the fermentation of sugar-extracted corn. The natural process of fermentation reduces energy consumption by up to 40% and greenhouse gas emissions by about 20% compared to petroleum-based materials.

To verify the recycled content of products, environmental and social impacts, and chemical restriction, we apply the Global Recycling Standard (GRS), which is assessed and certified by Control Union.

Natural fabrics

All main fabric is 100% natural fabric derived from cotton or wood pulp:

  • Cotton Fabric: Cotton fabric is a synthetic fiber, made of natural cotton fibers or mixed with other man-made fibers.
  • Modal Fabric: Modal fabric is a bio-based fabric made of recycled cellulose from the oak tree. Modal fabric is considered one of the materials that have a positive impact on the environment, because the oak tree does not need pesticides or chemicals to fertilize, and the biodegradability of the Modal fabric itself.
  • Tencel Fabric: Tencel fabric, also known as Lyocell, is the safest and most environmentally friendly biological fabric on the market today. Tencel has produced entirely from cellulose found in the wood pulp of trees belonging to the bamboo family such as eucalyptus trees.
  • Bamboo Fabric: Bamboo fabric, also known as bamboo fiber, is a type of cellulose fiber extracted from natural bamboo and other additives.
  • Hanji Fabric: Hanji material literally means "Korean paper". The main material for making Hanji fabric is mulberry bark fiber. Thousands of exquisite paper crafts have been produced in Korea's long history using mulberry bark fibers to make Hanji. Since then, Hanji material has been considered a cultural heritage and has continued to be developed for use in the field of bedding production, in the hope of directing customers to special values.

They are not only environmentally friendly fabrics but also types of fabrics that can protect customers’ health while bringing a smooth and pleasant feel.


Because of the environmental impact of plastic packaging, it has become our key concern over the years. To minimize the impact, we used D2W plastic packaging, which helps the plastic to decompose without leaving debris and methane gas, as the packaging for the product with a single-color bed sheet. For other plastic packaging, we prioritize suppliers with sustainable production processes and gradually replace them with recycled packaging that still ensures product durability and good preservation.
