1. Smell the odor. A good down comforter has a small or even no odor. If the taste is strong, the quality may not be good.

2. Check the workmanship. The main thing is to look at the stitching of the down quilt. A good down quilt should be evenly and meticulously stitched to ensure that there are no leaks or loose threads

3. Spread it out to see the rebound speed. Spread out the down jacket, and after two or three minutes, flatten it and observe its rebound recovery speed. The faster the rebound speed, the better the quilt. If the rebound speed is slow or does not rebound at all, attention should be paid.

4. Touch. Check the quality of the feel. A high-quality down quilt usually has a soft feel, with only a small amount of small hairs, which will quickly rebound when released. If there are many large hairs or hard substances in the quilt, then the quality of the quilt is usually not high.

5. Take a photo. Check if there is any fleece. Gently tap the down comforter to see if any fuzz or dust has escaped. A good down quilt will not have any shedding or dust leakage. In addition, during the tapping process, there should be no obvious hard particles or objects inside.

6. Dian. Look at the weight. Under the same volume size, the lighter the weight, the higher the velvet content, and the higher the warmth and comfort
