1.Slow Spring Back

The best time to bounce is 3 to 5 seconds. The memory foam is temperature sensitive. It changes through temperature changes. This rebound will be different every season. This is normal and you don't have to worry about using it.

2. Odor problem

The memory foam is made of polyurethane material and has been tested by international testing agencies. It has a slight odor and is not harmful to human health. After a while, the slight smell will disappear. It is much better to put the inner layer in a cool, ventilated place for 2-3 hours every 2-3 weeks.

3.Bubble

Memory foam pillows are technically molded and foamed at one time. This is normal and acceptable when some bubbles are created because the air in the mold is not completely removed when the sealing mold is molded.

4.Attentions

The interior of the memory foam pillow should not be exposed to the sun! Memory foam pillows can not be washed inside!

I believe that our cooperation will be long-lasting and win-win!
