Final Thoughts on the HyperVent
For the product to work properly, you need to ensure you allow air to flow in the newly created space underneath your mattress. If the mattress is pushed up against a wall, or the sides are covered with a heavy blanket, air won’t be able to flow through the HyperVent.
Like many RVs, our bedroom is on the small side. The head of the mattress pushes up against the wall. In an effort to increase airflow we have gotten in the habit of pulling the mattress away from the wall by just a few inches. We also fold the covers up and away from the sides of mattress to allow air to flow under the mattress and through the HyperVent.
