Guarantees good air circulation

Due to the large contact surface of my pocket spring mattress on a roller grate I had in the past - despite turning regularly - the problem is that the moisture could not be performed quickly enough from the mattress to the outside.
The result was unpleasant and unhealthy mold stains on the mattress.

Looking for a solution to my problem, I came across the mattress protectors offered here.
And am satisfied with the overall performance of the product.

The knobs are tight enough to ensure on narrower slatted those required for air circulation space between the mattress and rust.
The breathable material of Schones can ave a smooth air and moisture exchange.

Since then I have not had these problems.

Only when turning the mattress the schooner slipped like once. Here the knobs could be something like non-slip.

Conclusion:
I will now always make sure my bed in the future with an appropriate cover to be provided. Lowest cost for maximum benefit.
