Do you need something under the mat? Do you need sheets under the mat?

1, the mat can be laid directly or in the middle.

2, this is nothing to pay attention to, just sleep comfortably on it. Of course, if the weather is not very hot, it would be better to cover it with a sheet, and you can take off your mat at any time. If the weather is too hot, laying one less layer can also slightly increase the heat dissipation.

3. Try to make the back of the mat transparent. The softer the bottom, the easier it is to affect the effect of the floor mat. But a too hard bottom will make the mat slide easily and make it uncomfortable to sleep.
