Your pillows and quilts may have accumulated sweat due to prolonged use, causing the down to clump together, as I said, the first step: put it in a dry and ventilated place for 2-3 days, or dry it in a dryer for 30 minutes Let the pillow dry well (remember not to expose it to the sun, which will yellow the cotton fabric). The second step is to wait until the pillow is dry, knead the pillow with both hands, fold it in half and beat it repeatedly, let the air fill the pillow, and the pillow will slowly return to a fluffy state.
We recommend drying your pillows and quilts once a month to help keep them fluffy and hygienic.
