Malouf Isolus Mattress Topper

At two inches thick, this topper adds a noticeable layer of cushioning without completely changing the feel of your mattress. It is best for softening a bed that feels slightly too firm or for adding a responsive, contouring layer to an older mattress.

Memory foam is naturally insulating, but this topper is designed with an open-cell structure and ventilation channels to actively promote airflow. While it won't feel like a cooling gel pad, these features help dissipate heat more effectively than standard memory foam.

The topper does not include straps or a non-slip backing. Because it is a foam layer, it relies on the friction between your mattress and a fitted sheet to stay in place; using a deep-pocket fitted sheet over both the topper and the mattress is the most effective way to keep it secure.

Yes, the flexible nature of this two-inch memory foam allows it to bend and conform to the movement of an adjustable base without cracking or losing its shape.

While you can technically use it sooner, it is best to let the topper expand in a well-ventilated room for at least 24 to 48 hours. This allows the foam to fully decompress to its intended thickness and helps dissipate any initial manufacturing scent.
