Rotate the mattress: Every three to six months, rotate your mattress to ensure even wear. This practice prevents specific areas from becoming overly compressed and maintains the mattress’s shape. Research indicates that rotating can prolong mattress life by distributing weight evenly (Mattress Research Institute, 2021).
Use a mattress protector: A high-quality mattress protector can shield the foam from spills and stains. According to the National Sleep Foundation (NSF, 2020), a protector also adds a layer of comfort. Opt for a breathable, waterproof option that allows airflow while safeguarding your investment.

Allow airflow: Ensure your mattress is properly ventilated. Elevate it occasionally to help moisture escape, as trapped moisture can lead to mold growth. The Environmental Protection Agency (EPA, 2021) emphasizes maintaining indoor humidity levels to prevent mold.
Store properly: If you need to move or store your mattress, keep it flat and in a cool environment. Avoid bending or folding it, as this can permanently damage the foam. The Better Sleep Council (BSC, 2020) advises that proper storage preserves mattress integrity.
