How Often Should You Replace Your Mattress?

Jun 18, 2025

 

A good night’s sleep is essential for maintaining physical health, mental clarity, and overall well-being, making the condition of your mattress a critical factor in sleep quality. However, even the best mattresses degrade over time, raising the question: how often should you replace your mattress? 

The Lifespan of Different Mattress Types

The durability of a mattress depends on its construction and materials. On average, mattresses last between 7 to 10 years, but this varies by type:

  • Foam Mattresses: Memory foam and latex mattresses typically last 7-10 years. High-density foam offers better longevity, but sagging can occur if the material breaks down, especially under the weight distribution of stomach sleeping.

  • Hybrid Mattresses: Combining foam and innerspring coils, hybrids often last 8-10 years. The coil system provides durability, but foam layers may compress over time, necessitating replacement.

  • Innerspring Mattresses: Traditional coil mattresses generally last 5-7 years. The springs can lose support, leading to an uneven surface that exacerbates discomfort for stomach sleepers.

Regular use, body weight, and maintenance practices further influence lifespan, making periodic evaluation essential.

Signs It’s Time to Replace Your Mattress

Recognizing when a mattress no longer supports healthy sleep is key to maintaining optimal rest. Consider the following indicators:

  • Sagging or Uneven Surface: Visible dips or lumps, particularly in the pelvic area for stomach sleepers, signal loss of support, potentially causing spinal misalignment.

  • Persistent Discomfort: Waking up with lower back pain, neck stiffness, or numbness suggests the mattress fails to contour to your body’s needs.

  • Allergies or Respiratory Issues: Dust mites, mold, and allergens accumulate over time, especially in mattresses older than 7 years, impacting sleep quality.

  • Visible Wear: Tears, fraying edges, or protruding coils indicate structural failure, reducing effectiveness.

Experts recommend replacing a mattress every 7-10 years, with stomach sleepers potentially needing earlier replacement if firmness diminishes, as this position demands robust support.

Factors Influencing Replacement Frequency

Several variables affect how often you should replace your mattress:

  • Body Weight: Heavier individuals (over 230 pounds) may compress materials faster, shortening lifespan to 5-7 years.

  • Sleep Position: Stomach sleepers exert concentrated pressure on the mattress, accelerating wear if the firmness level is inadequate.

  • Maintenance: Rotating the mattress every 3-6 months and using a mattress protector can extend its life by preventing sagging and allergen buildup.

  • Manufacturer Warranty: Most warranties cover 10 years, but this reflects minimum durability, not optimal performance.

Monitoring these factors ensures timely replacement, preserving sleep health.

Health Implications of an Old Mattress

An aging mattress can compromise health, particularly for stomach sleepers. Prolonged use of a sagging mattress may lead to chronic lower back pain due to improper spinal alignment. Studies suggest that mattresses over 10 years old harbor significant allergen loads, potentially triggering asthma or allergies. Replacing your mattress proactively can mitigate these risks, enhancing sleep quality and overall wellness.

Expert Recommendations

Sleep experts, including those at the National Sleep Foundation, advocate replacing mattresses every 7-10 years, with adjustments based on personal comfort and health. For stomach sleepers, opting for a firm mattress (7-8 on a 10-point scale) and replacing it when signs of wear appear—typically around 7 years—ensures continued support. Regular assessments, such as a yearly check for sagging, can guide this decision.

 

Determining how often to replace your mattress hinges on its type, usage patterns, and physical condition. For stomach sleepers, prioritizing firmness and monitoring for wear can prevent health issues like back pain and improve sleep quality. Staying proactive with replacement every 7-10 years, or sooner if needed, is a proven strategy for maintaining optimal rest.
