How Long Does it Take to Break in a Mattress?

Key Takeaways

  • The Break-In Period Varies: When you invest in a new mattress, it’s essential to recognize that it will have a break-in period, often referred to as the “adjustment period.” This period is influenced by factors like mattress type and materials. On average, it can take 30 to 90 days for a mattress to fully adapt to your body and reveal its true comfort level.
  • Factors Affecting Break-In Period: The time it takes for your mattress to break in depends on several factors, including the type of materials used in the mattress, its density, your sleep habits, room conditions, frequency of use, and the mattress design. Understanding these factors can help you manage your expectations and optimize the break-in process.
  • Tips for a Smooth Break-In: To ensure a successful break-in period, be patient and persistent. Rotate your mattress regularly, try different sleeping positions, use the right foundation, and give your mattress a chance to adapt. If you find that your mattress remains too firm or too soft well beyond the break-in period, it may be a sign that it’s not the right fit for your comfort and support needs.

When you invest in a new mattress, you’re embarking on a journey to discover the perfect balance between comfort and support.

Just like a new pair of shoes that needs breaking in, a mattress also requires time to adapt to your body’s unique contours and sleep preferences.

But how long does it take to break in a mattress?

Let’s delve into this fascinating process and uncover the secrets to unlocking optimal comfort for a restful slumber.

The Break-In Period: What to Expect?

A new mattress might feel slightly different initially as it adjusts to your weight, shape, and sleep habits.

The break-in period, known as the “adjustment period,” varies depending on the mattress type and materials.

On average, it can take 30 to 90 days for a mattress to break in and reveal its true comfort level fully.

Factors Affecting the Break-In Period: Decoding the Comfort Evolution

The break-in period of a mattress is like the unfolding of a story, with each chapter revealing a new layer of comfort and support.

While there’s no fixed duration for this process, understanding the various factors that influence how long it takes for your mattress to reach its peak comfort level can provide valuable insights into your sleep experience.

1. Materials Matter:

Different mattress materials behave differently during the break-in period.

Here’s a look at how various materials can influence the adaptation process:

  • Memory Foam: Memory foam mattresses might require a longer break-in period due to their unique contouring properties. The viscoelastic foam responds to body heat, gradually molding to your shape over time.
  • Latex: Natural latex mattresses tend to have a shorter break-in period. They offer a consistent feel from the start, providing a balanced combination of support and responsiveness.
  • Innerspring: Innerspring mattresses with pillow tops might feel comfortable sooner due to the added cushioning, while those without a pillow top may take longer to conform to your body.

For different types of mattresses, here’s the average break-in time:

Mattress MaterialAverage Break-In Period
Memory Foam30 – 90 days
Latex14 – 30 days
Innerspring7 – 14 days
Hybrid (Memory Foam)30 – 90 days
Hybrid (Latex)14 – 30 days
Hybrid (Innerspring)7 – 14 days
Air Mattress7 – 14 days
Waterbed7 – 14 days


2. Density and Support:

The density of mattress foam plays a role in the break-in process.

Higher-density foams generally take longer to break in, but they also tend to provide more extended support over time.

These foams can offer a balance between initial comfort and long-term durability.

3. Sleep Habits and Weight Distribution:

The way you sleep influences how quickly your mattress breaks in.

If you sleep in various positions and distribute your weight differently across the mattress, it’s likely to adapt more evenly. Consistently sleeping in one position might cause that area to break in faster than others.

4. Room Temperature and Humidity:

Temperature and humidity can affect how materials respond during the break-in period. Extreme conditions might impact the feel of the mattress.

Maintaining a stable sleep environment is essential to ensure a consistent adaptation process.

5. Frequency of Use:

Using your mattress regularly is key to speeding up the break-in process. The more you sleep on it, the quicker it will adjust to your body.

If you use your mattress infrequently, it might take longer to conform to your shape.

6. Body Heat and Pressure:

Your body heat and pressure play a role in softening the mattress’s materials.

As you sleep on the mattress, your body weight and warmth help it gradually contour to your curves, resulting in improved comfort.

7. Mattress Type and Design:

Different mattress designs can influence the break-in period.

For example, mattresses with multiple layers or complex constructions might take longer to break in, while simpler designs might adapt more quickly.

8. Mattress Foundation:

The foundation you use can affect how the mattress breaks in. Using a foundation incompatible with your mattress type might hinder the adaptation process.

Breaking In Your Mattress: Tips and Tricks

The journey of breaking into a mattress is a tale of transformation – the evolution from a pristine surface to a haven of personalized comfort.

Just as a new pair of shoes needs time to mold to your feet, a mattress requires patience and care to reach its optimal comfort level.

Here’s a comprehensive guide with tips and tricks to help you navigate the process and ensure your mattress becomes your ideal sleep companion.

  1. Be Patient But Persistent: Understand that breaking in a mattress is a gradual process, and you won’t experience instant comfort from day one. Give it time to adjust to your body contours, sleep habits, and weight distribution.
  2. Rotate Regularly: Rotating your mattress regularly during the break-in period helps evenly distribute your body weight and pressure across the surface. This prevents certain areas from breaking in faster than others, ensuring a consistent feel.
  3. Sleep All Over: During the first few weeks, try different sleeping positions to allow the mattress to adapt evenly. By alternating between the side, back, and stomach sleeping, you encourage a balanced break-in process.
  4. Use the Right Foundation: Ensure you use a compatible foundation or bed frame for your mattress type. The proper support prevents uneven wear and aids in the break-in process.
  5. Give It a Chance: While you might notice immediate changes in the feel of your mattress, it’s essential to continue using it regularly for at least a month before making a final judgment about its comfort level.
  6. Add a Mattress Topper: A high-quality mattress topper can help soften the feel of a new mattress, making it more comfortable during the break-in period. Opt for a topper with a thickness and material that complements your mattress type.
  7. Gradual Transition: If your previous mattress had a different firmness level, transitioning to a new mattress might require adjustment. Start by spending a few hours on the new mattress each night and gradually increase the duration.
  8. Avoid Jumping or Placing Heavy Objects: During the break-in period, avoid jumping or placing heavy objects on the mattress. This can cause uneven compression and impact its overall feel.
  9. Stay Hygienic: Use a mattress protector to clean your new mattress during the break-in process. This prevents any spills or accidents from affecting the comfort of your mattress.
  10. Monitor Your Comfort: Regularly assess your comfort level while using the mattress. Take note of any changes in your sleep quality or any discomfort you may be experiencing.
  11. Follow Manufacturer Recommendations: Each mattress type and brand might have specific recommendations for breaking in. Refer to the manufacturer’s guidelines to ensure you’re treating your mattress in the best possible way.
  12. Seek Professional Advice: If you’re unsure about the break-in process or have concerns about your mattress’s comfort level, don’t hesitate to contact the manufacturer or retailer for guidance.

Signs Your Mattress Is Too Firm

Even though a mattress may be initially firm, it’s important to differentiate between being inherently firm and needing time to break in.

Here are signs that your mattress might feel too firm during the break-in period:

  1. Initial Discomfort: When you first sleep on a new mattress, especially if made from materials that need to conform over time, it might feel excessively firm. This initial discomfort can be mistaken for the mattress being inherently too firm.
  2. Lack of Conformity: During the break-in period, you might notice that the mattress cannot conform to your body’s shape. This can make it feel unyielding and less comfortable than expected.
  3. Pressure Points: A new mattress might create pressure points if it hasn’t fully adjusted to your body’s contours yet. These pressure points can lead to discomfort until the mattress softens and molds to your body over time.
  4. Stiffness: Due to the firmness and lack of initial flexibility, you might experience stiffness in your muscles and joints, especially if your body is used to a softer mattress.
  5. Reduced Hug: Mattresses that become softer with time often provide a “hugging” sensation as they conform to your body. This sensation might be limited during the break-in period, making the mattress feel too firm for your preference.
  6. Restlessness: As the mattress adjusts to your movements and body shape, you might experience restlessness during the break-in period. This can be mistaken for the mattress being too firm.
  7. Sleep Disruption: Similar to restlessness, the lack of immediate comfort and adjustment might disrupt your sleep initially, making the mattress seem firmer than it is.
  8. Change in Feel: If you’ve previously had a softer mattress, transitioning to a new, firmer one can initially feel uncomfortable, even though it’s just a matter of getting accustomed to the new feel.

Signs Your Mattress Is Too Soft

During the break-in period, a mattress might also feel overly soft, especially if designed to conform to your body’s shape gradually.

Here are signs that your mattress might feel too soft during the break-in period:

  1. Excessive Sinking: If your mattress is excessively soft, you might notice that you sink too deeply into it. This sinking can lead to an uncomfortable alignment of your spine and joints.
  2. Lack of Support: A too-soft mattress might lack the necessary support for your body, leading to poor spinal alignment. This can cause discomfort and even pain, especially in areas like your lower back.
  3. Feel of Unevenness: A mattress that is too soft might feel uneven as it molds to your body. This unevenness can result in discomfort and prevent you from finding a comfortable sleeping position.
  4. Quick Wear: Excessive softness can lead to quicker wear and tear of the mattress, as the materials might break down more rapidly than with a firmer mattress.
  5. Loss of Edge Support: An overly soft mattress might lack proper edge support, causing you to feel like you’re rolling off the bed and making it harder to sit or sleep near the edge.
  6. Difficulty Changing Positions: Too much softness can make it challenging to change sleeping positions at night, as you might feel trapped or engulfed by the mattress.
  7. Heat Retention: Some softer mattresses, especially those with thick memory foam layers, can trap body heat and lead to discomfort from overheating.
  8. Allergies and Dust: Extremely soft mattresses might accumulate more dust and allergens, potentially causing breathing difficulties for sensitive individuals.
  9. Body Aches: If your mattress is too soft, you might wake up with body aches and pains, indicating that your body isn’t receiving the necessary support during the night.
  10. Restlessness: Similar to a too-firm mattress, an excessively soft one can also cause restlessness during the break-in period as your body adapts to the new feel.

It’s important to give your mattress ample time to break in and for you to get accustomed to its feel.

However, if you consistently experience discomfort and the signs of excessive softness persist well beyond the break-in period, it might indicate that the mattress isn’t a good fit for your preferences and needs.
