Understanding what causes a mattress to sag over time is key to getting the best support and longevity from your bedding investment. Over the years, mattresses naturally wear down, and sagging is one of the most common signs your bed might need an upgrade. If you’ve noticed dips or uneven spots forming where you sleep, you’re likely experiencing mattress sag, but what exactly leads to this?
Several factors come into play when exploring what causes a mattress to sag over time. Here are some key contributors:
Body Weight & Pressure: Continuous pressure in specific areas (such as the hips and shoulders) compresses the mattress materials, resulting in visible dips.
Material Fatigue: Over time, springs lose their tension, and foam or padding can soften,...

Several factors come into play when exploring what causes a mattress to sag over time. Here are some key contributors:
- Body Weight & Pressure: Continuous pressure in specific areas (such as the hips and shoulders) compresses the mattress materials, resulting in visible dips.
- Material Fatigue: Over time, springs lose their tension, and foam or padding can soften, both of which diminish support and structure.
- Improper Foundation: Placing your mattress on an old or unsuitable base can accelerate sagging, as the foundation may not provide adequate, even support.
- Moisture & Humidity: Accumulated moisture from body heat or the environment can weaken the mattress core, especially if proper ventilation isn’t maintained.
- Poor Rotation: Failing to rotate or flip (when designed for it) means one area bears most of the weight, leading to premature sagging.
Still weighing whether to replace your sagging mattress? Here’s a quick comparison of the pros and cons of living with a sagging mattress versus seeking a solution:

Cons |
