All our filling line products are manufactured by our self to maintain our product quality standard as we don't rely on resourcing them from third parties. A grade virgin hollow conjugated fibre is used to stuff our products to enhance the cushion effect. we don't use regenerated or recycled fibre unlike some other sellers and they don't even mention clearly in the description of their product. You can easily identify this from a photo or when item arrives, if it has a grey like appearance or look then it is not a virgin fibre. Recycled fibre goes flat quicker than Virgin fibre.
