Do New Mattresses Get Softer? How Firmness Changes Over Time

Wondering “Do new mattresses get softer?” after your first few nights on a bed that feels firmer than expected? You’re not alone. Many people notice their new mattress softens over the first weeks and want to know what’s normal, what’s not, and how long it should take.

This FAQ-style guide explains why and how new mattresses get softer, what to expect with different materials, and when a mattress may simply be too firm for you.

Do New Mattresses Get Softer Over Time?

In most cases, yes, new mattresses do get softer during an initial “break‑in” period.

When you first sleep on a new mattress, the materials are fresh, tight, and not yet adjusted to your body weight and sleeping style. As you use the mattress:

Foams compress and adapt
Fabrics relax
Support layers settle into a more natural position

This usually leads to a slightly softer, more conforming feel compared to day one.

However, a very firm mattress will not transform into a plush one. Break‑in typically means a modest softening, not a complete change in firmness level.

How Long Does It Take for a Mattress to Soften?

Most people experience noticeable softening within the first few weeks of regular use.

General timelines (can vary by brand and build)

Days 1–7: Mattress may feel firmer than expected; materials are still tight.
Weeks 2–4: Many sleepers notice the mattress becoming more comfortable and less “stiff.”
Weeks 4–8: The feel tends to stabilize into its long‑term firmness, with only gradual changes after that.

This is why many mattress companies suggest trying a new mattress for at least several weeks before deciding whether it’s too firm or too soft.

Do Different Types of Mattresses Get Softer Differently?

Yes. The answer to “Do new mattresses get softer?” depends partly on the materials used.

Memory foam & other foam mattresses

Often feel quite firm at first, especially in a cool room.
Tend to soften noticeably over the first few weeks as the foam cells open up and respond to body heat and pressure.
Over time, they usually develop a more conforming, cushioned feel, but quality and density affect how much and how quickly.

Hybrid mattresses (foam + coils)

Usually have a shorter break‑in period than all‑foam beds.
Comfort layers (foams, fibers) soften somewhat, while coil support stays fairly consistent.
Many sleepers feel moderate softening without a dramatic change in support.

Innerspring mattresses (mostly coils with thinner comfort layers)

May feel springy and firm at first.
Pillow tops or foam layers on top can soften slightly, but the overall support often remains relatively stable.
Changes can feel more about the top layer relaxing than a deep softening.

How Much Softer Will My Mattress Really Get?

A new mattress usually becomes more comfortable and slightly less firm, but you should not expect a major change in firmness level.

Think of it this way:

A “firm” mattress may relax into “medium‑firm.”
A “medium‑firm” mattress might soften to feel closer to “medium.”
A very firm mattress is unlikely to ever feel “plush.”

If your mattress feels extremely uncomfortable from the start, hoping it will soften into your ideal feel may not be realistic.

Can I Help My New Mattress Soften More Evenly?

You cannot change the basic firmness design, but you can help the break‑in feel smoother and more even.

Some commonly used approaches include:

Sleeping on it every night so materials adjust to your body.
Changing your sleeping position occasionally to avoid compressing the same spots only.
Walking or gently pressing across the surface (without jumping) to encourage uniform softening.
Using a light mattress protector rather than very thick pads at first, so you feel the mattress more directly.

If you prefer a much softer surface but like the underlying support, some people add a mattress topper for more cushioning while the mattress continues its natural break‑in.

When Is a Mattress Just Too Firm?

If you’ve given your bed several weeks and you’re still asking “Do new mattresses get softer, or is this it?”, you may be near its natural limit.

You might consider that the mattress is simply too firm for you if:

You consistently wake up feeling stiff or sore from pressure points.
You struggle to stay comfortable in your usual sleeping position.
The mattress feels about the same after several weeks of regular use.

In these cases, it’s often more about personal preference and body type than a defect. Some sleepers feel best on firmer surfaces; others need more cushioning for comfort.

Does Softening Mean the Mattress Is Wearing Out?

Normal break‑in is different from long‑term sagging or deterioration.

Early softening (first weeks/months):
- Usually light and even.
- Mattress still feels supportive and balanced.
Wear and tear over years:
- May show visible impressions, dips, or uneven areas.
- Can feel like reduced support, not just softness.

A small amount of softening early on is expected and does not automatically mean the mattress will wear out quickly. The rate of long‑term change depends on build quality, materials, and how the mattress is used.

✅ Quick Mattress Takeaways

Key points about “Do New Mattresses Get Softer”

Yes, most new mattresses get softer during a normal break‑in period.
Softening is usually most noticeable in the first 2–8 weeks of use.
Foam mattresses often show the greatest early softening; hybrids and innersprings tend to change more mildly.
Break‑in typically means a slight shift in firmness, not a complete transformation from firm to plush.
You can encourage even softening by using the mattress regularly and varying where you lie.
If your mattress still feels uncomfortably firm after several weeks, it may be the wrong firmness for your needs, rather than just “not broken in” yet.
Normal softening is expected and different from long‑term sagging or loss of support.

Understanding how and why new mattresses get softer can make the first weeks on a new bed less confusing and help you judge whether your mattress is simply breaking in—or not the right firmness for you.
