How to Make a Memory Foam Mattress Firmer

Memory foam mattresses conform to your body and should provide added comfort due to their innovative technology. The secret to memory foam mattresses is their temperature-based technology. They become softer and conform to your body based upon your body heat. Therefore, they're firmer in cooler temperatures. If your memory foam mattress is too soft for you, make it firmer by adjusting the temperature of the mattress.

Instructions

    • 1

      Purchase Coolmax sheets, which cool the temperature of your bed. Sheets with Coolmax technology allow your body heat to pass through the fibers of the fabric, allowing for more breathability and less body heat retention, which makes your memory foam mattress cooler. This makes your memory foam mattress firmer, because memory foam mattresses become firmer when they're cooler.

    • 2

      Add a mattress topper or pad to your memory foam mattress. The added padding can provide you a firmer foundation upon which to lie.

    • 3

      Set your thermostat to approximately 65 degrees Fahrenheit. Again, pulling from the principle above, because memory foam mattresses adjust to temperature, a cooler temperature makes your mattress feel firmer.
