Cold Weather Impacts on Memory Foam

Memory foam is a popular material in mattresses, pillows, and other bedding products due to its ability to contour to the body and provide superior support. However, like many materials, memory foam can be affected by temperature changes—especially cold weather. If you’ve ever noticed your memory foam mattress feeling firmer on chilly mornings, you’re not going crazy. Cold temperatures can significantly impact the feel of memory foam.

How Cold Weather Affects Memory Foam

1. Increased Firmness

Memory foam is temperature-sensitive, meaning it reacts to body heat and ambient temperature. When the temperature drops or it gets colder, the material stiffens and becomes firmer. This is because memory foam is made of viscoelastic polyurethane, which hardens in lower temperatures, making it less responsive to body weight and pressure.

How This Affects Sleep:

• Your mattress may feel noticeably harder when you first lie down.
• It may take longer to conform to your body shape, reducing initial comfort.

2. Slower Response Time

Memory foam is known for its ability to “bounce back” slowly, molding around the body and returning to its original shape once pressure is removed. However, in colder temperatures, this process slows down significantly. You might notice that your mattress or pillow takes longer to return to its normal shape when you change positions.

How to Prevent Cold Weather Issues with Memory Foam

1. Maintain a Warm Room Temperature

Keeping your bedroom at a consistent temperature (ideally between 65-75°F) can help maintain the responsiveness and comfort of your memory foam mattress.

2. Allow Time for Adjustment

If your mattress feels firm after a cold night, give it some time to warm up with your body heat before expecting it to soften completely. Sitting or lying on the mattress for a few minutes can help speed up this process.

3. Avoid Storing Memory Foam in Cold Conditions

If you need to transport or store memory foam products, try to keep them in a temperature-controlled space. If they do get cold, let them warm up gradually before using them to prevent damage.

If you have any memory foam products shipped to you during colder temperatures, it’s very normal to experience slower expansion or extra firmness, due to the impact of the colder temperatures. Allow it to warm up in a temperature-regulated area for 72 hours and it will be good to go!
