For some people, memory foam mattresses are too hot to sleep in comfortably at nighttime. This is because heat from the body is contained within the mattress to help the foam retain the body's shape. There are ways to reduce the amount of heat, however, without disturbing the memory foam's ability to conform to your shape as you sleep. Before you decide to return your mattress, consider these easy adjustments to help reduce the heat you feel while sleeping.

  1. 1

    Purchase sheets with a thread count of 350 or more. High thread count sheets are commonly made from natural materials like cotton or silk. These materials can help keep you cool while you sleep.

  2. 2

    Purchase a mattress topper made with a polyester filling. This helps redistribute body heat without compromising the ability of the memory foam to conform to your body.

  3. 3

    Make your bed using thin blankets or quilts instead of heavy comforters. Thin blankets and quilts can be removed during the night to help you feel more comfortable.

  4. 4

    Choose sleepwear made from natural materials such as silk, cotton, or blended cotton. Natural fibres allow for increased breathability, which can reduce sweating when sleeping. Avoid heavy flannel, rayon, or sleepwear made from polyester.

Tips and warnings

  • Purchase a memory foam mattress that has "air channels" built in to distribute heat more evenly. Memory foam mattresses that have a fibre comfort layer on top can also help reduce heat while you sleep.
  • Return your memory foam mattress to the manufacturer or mattress store within the trial period to receive a full refund. Returning after the trial period may result in no refund or a partial refund.
