Handmade mountain brown mattress, after a period of time with the surface of the unevenness of how it is

Mountain brown mats are generally not handmade, he is made of brown silk + gluing process, so its resilience is very poor, so it is easy to collapse. Will cause damage to the waist. And the glue contains formaldehyde and benzene is not environmentally friendly.

It is recommended to use a good spring bed, like brown mat people like to sleep in a hard bed, so it is recommended to change the hard spring bed. The U.S. Aimon's mat is good I use it
