Things to Consider

Bear in mind that a bed topper isn’t always the solution. If your mattress is old, sagging or broken in some way - these are signs it’s time for a replacement. You need to ensure your bed provides high levels of support, particularly if you mattress is heavy. For example, if the slats are too far apart, this may cause your mattress to sag. Choose a high-quality bed frame to prevent this from happening.
