Can I use Ereada Mat on a waterbed

It depends on the type of waterbed.

Although the mat contains reflective layers that direct most of the heat upward, the bottom of the mat can still become quite warm.

For this reason, we usually recommend placing a towel under the mat if you use it on a foam mattress or hardwood floor, as these surfaces may be sensitive to heat.

If your waterbed can safely tolerate temperatures around 120–130°F on its surface, it should generally not be a problem.

Another important factor is the firmness of the surface. The mat needs some level of support. It does not have to be as rigid as a wooden board, but it should not be excessively soft.

If the waterbed maintains its shape and does not wrap tightly around your body when you lie on it, it should provide sufficient support for the amethyst mat.
