Method 1: replace the filler.
First of all, we can consider whether we need to replace a filler. If the feather pillow collapses, it is likely that the filler inside is compressed or faulty. We can solve this problem by taking out the filler and refilling it, or buying soft fillers again.
Method 2: Vibration.
If it is not easy to replace the filler, then we can restore the original shape of the pillow by vibration. Specifically, we can put the pillow in a dry place, and then shake it hard to make the down or filler in it disperse again. This method is especially effective for down pillows.
Method 3: Change the usage habits.
Finally, we can change our habits and reduce the occurrence of pillow collapse. For example, we don't have to put the pillow in the same position for a long time, we can turn it over regularly to make it difficult to compress, and we can also choose a stronger filler to increase the retention of the pillow.
To sum up, the collapse of sofa feather pillow can be repaired by replacing filler, vibrating or changing usage habits. Different methods have different application scenarios, so we need to choose the most practical way to repair the pillow according to the specific situation.
