Why your new mattress feels firmer: The key factors
Experiencing a surprisingly firm mattress after getting it home is a very common scenario. This phenomenon can be attributed to several factors, with the most significant being the material's adaptation process, often referred to as the "break-in period."
The mattress break-in period
Just like a new pair of shoes, a new mattress needs time to adjust. The materials, such as foam, coils, and fibers, are compressed during manufacturing, shipping, and packaging. Once unrolled and placed on your bed, these materials need time to decompress and relax. This process is the primary reason why is my new mattress firmer than the store.
- Foam layers: Memory foam and other types of foam soften with use, body heat, and pressure. A new foam mattress will feel denser and more rigid until these factors have worked their magic.
- Coil systems: Innerspring mattresses also have a break-in period. New coils are at their maximum tension and will soften and become more pliable as they are used.
- Fibers and upholstery: The surface layers and padding can also be stiff initially. These materials will become more flexible over time as they conform to your body shape.
Showroom wear and tear
The mattresses you test in a showroom have been tested by dozens, if not hundreds, of people. This constant use has already completed the break-in process for you. The store model is a well-used representation, not a factory-fresh one.
- Constant pressure: The constant body weight and movement of potential customers have pre-softened the materials, giving you a false sense of what the mattress will feel like straight out of the box.
- Environmental factors: Showroom floors are typically temperature-controlled, which can also affect foam responsiveness. Your bedroom temperature might differ and influence how the mattress feels.
Comparison of new vs. showroom mattress
| Feature | New Mattress | Showroom Mattress |
|---|---|---|
| Firmness | Maximum firmness, can feel stiff | Softer, has already broken in |
| Materials | Compressed and dense | Relaxed and adaptable |
| Support | Can feel overly rigid at first | Contoured to many different bodies |
| User History | None | Extensive, many people have tested it |
| Feel | Awaits your customization | Already personalized by use |
Shipping and compression effects
Modern mattresses, especially memory foam and bed-in-a-box models, are often compressed and vacuum-sealed for shipping. This intense compression can temporarily change the material structure. It takes time for the mattress to fully decompress and reach its intended size and feel.
- Boxed mattresses: These require up to 48 hours or more to fully expand after being unboxed. During this time, they will feel much firmer than they ultimately will.
- Traditional mattresses: While not compressed in a box, they are often wrapped tightly, which can affect the initial feel of the top layers.
Foundation and support issues
The base you place your mattress on can significantly affect its feel. A weak or unsupportive foundation can make even a soft mattress feel firm. Conversely, a firm, solid base can make a brand-new mattress feel even firmer.
- Bed frame type: Ensure your bed frame is compatible with your mattress. A box spring on a foam mattress, for example, is generally a bad idea and can alter its feel.
- Slats and spacing: For slatted bases, the slats must be close enough together to provide adequate support and prevent the mattress from sagging or feeling too hard.
What you can do to speed up the process
While the break-in period is necessary, you can take some steps to accelerate it:
- Walk on the mattress: Spend a few minutes walking on the surface of the bed. This applies pressure and helps soften the foam and fibers.
- Regular use: The best way to break in a mattress is to sleep on it every night. Your body weight and heat are the most effective tools.
- Rotate the mattress: If your mattress is one-sided, you can rotate it head-to-toe every few weeks to ensure even wear across the surface.
- Increase room temperature: A slightly warmer room can help memory foam and similar materials become more pliable faster.
Give it time: The 30 to 90-day window
As mentioned in the introduction, most manufacturers recommend a 30 to 90-day adjustment period. This is the window during which your body adjusts to the new mattress and the mattress adjusts to your body. Many people notice a significant difference after just a few weeks.
If you're still experiencing excessive firmness after this period, it may be worth investigating the manufacturer's return policy or comfort exchange options. Understanding that your new mattress requires a period of adaptation is key to a successful transition.

Conclusion: Patience is key for better sleep
The initial feeling of excessive firmness from your new mattress is a temporary phase. The difference between the showroom model and your new bed is primarily due to the break-in period. By understanding this process and giving your mattress the necessary time to adapt, you will be well on your way to enjoying a comfortable and supportive night's sleep.
