BOROSTYÁN FR mattress recommended over a tunable bed rail 

With our BOROSTYÁN mattresses, we have completely eliminated polyurethane foam from the production process with our proprietary technology, while retaining all the popular and well-known properties. The mattress core is not built into a foam cradle, but is enclosed by a twin edge frame system with auxiliary springs and corner protection. In this way, the lying surface is sprung from edge to edge, with the same elasticity character across its entire width.
Lying comfort feature: form fitting that is of medium firmness.

The cover of our >BOROSTYÁN FR< mattress is made of durable, flame-retardant fabric. Underneath the layer that covers the mattress and ensures comfort, we also place a water-repellent membrane layer to prevent liquids from penetrating the inner core of the mattress during wet cleaning, which may be necessary in some cases.
