How to Add Firmness to a Memory-Foam Mattress
- 1). Keep your room at 55 to 60 degrees Fahrenheit. Memory foam becomes firmer at colder temperatures.
- 2). Allow the mattress to adjust to the cooler temperature before using.
- 3). Place a mattress pad on top of the memory-foam mattress. These mattress pads can be found at most home-goods stores and come in a range of firmness levels. Eggshell-crate mattress pads can instantly add firmness to the mattress and are also easily removable if needed.
