If you regularly feel too warm in bed, your mattress may not provide the temperature comfort you prefer. Room temperature, bedding, sleepwear, airflow and personal preferences can all affect how warm or cool your sleep environment feels.

Your mattress is another important part of that environment. Sleep Number® mattresses offer a range of temperature-focused features, from cooling materials designed to help create a comfortable sleep surface to advanced active cooling and warming technology available on select mattresses.

If your current mattress no longer aligns with your temperature preferences, here are some reasons it may be time to explore your options.

You Often Feel Too Warm in Bed

If you frequently throw off the covers, flip your pillow or search for a cooler spot on your mattress, your sleep environment may feel warmer than you'd like.

Consider Your Entire Sleep Environment

Before replacing your mattress, consider the different factors that may be contributing to how warm you feel:

  • Room temperature

  • Humidity and airflow

  • Bedding materials and weight

  • Sleepwear

  • Mattress materials and construction

  • Personal temperature preferences

Making small changes to your bedding or bedroom may help. If you still feel uncomfortable, it may be helpful to explore a mattress with cooling capabilities.
