Understanding Mattress Firmness: How to Choose the Right Level for You

Selecting the right mattress is essential for a comfortable and restful night’s sleep, and one of the most critical factors to consider is mattress firmness. With numerous options available, it can be challenging to determine which firmness level is best suited to your individual needs and preferences. In this article, we will explore the various mattress firmness levels, discuss their benefits and drawbacks, and provide guidance on how to choose the right firmness level for you.

  Mattress firmness scale

Mattress firmness is typically measured on a scale of 1 to 10, with 1 being the softest and 10 being the firmest. Most mattresses on the market fall within the 3 to 8 range. To better understand the different firmness levels, here is a brief overview of the firmness scale:

  • Soft (1-3): Soft mattresses offer a plush, cushioned feel that allows for significant sinkage and contouring. They are best suited for side sleepers or those who prefer a “hugging” sensation from their mattress.
  • Medium (4-6): Medium-firm mattresses provide a balance of comfort and support, with a moderate level of sinkage and contouring. They are suitable for a wide range of sleepers, including side, back, and combination sleepers.
  • Firm (7-10): Firm mattresses offer a solid, supportive sleep surface with minimal sinkage and contouring. They are ideal for back and stomach sleepers or those who require additional support for proper spinal alignment.

  Factors to consider when choosing mattress firmness

Several factors can help guide your decision when selecting the right mattress firmness for your needs. Consider the following aspects to ensure a comfortable and supportive sleep experience:

  • Sleep position: Your preferred sleep position plays a significant role in determining the ideal mattress firmness. Side sleepers generally require a softer mattress to allow for proper contouring and pressure relief, while back and stomach sleepers often benefit from a firmer mattress to maintain proper spinal alignment.
  • Body weight: Your body weight can also influence the level of support and comfort provided by a mattress. Heavier individuals (230 lbs or more) may require a firmer mattress to prevent excessive sinkage and maintain proper support, while lighter individuals (130 lbs or less) may find more comfort in a softer mattress that allows for adequate contouring and pressure relief.
  • Personal preference: Ultimately, your personal preference plays a significant role in determining the right mattress firmness. Some individuals may prefer the plush, cushioned feel of a softer mattress, while others may enjoy the supportive, stable feel of a firmer mattress. It’s essential to consider your own comfort preferences when making your decision.

  The benefits and drawbacks of various firmness levels

Each mattress firmness level has its own set of benefits and drawbacks, depending on your sleep position, body weight, and personal preferences. Here is a brief overview of the advantages and disadvantages of soft, medium, and firm mattresses:

  • Soft mattresses:
    • Excellent pressure relief and contouring, particularly for side sleepers
    • A plush, luxurious feel that provides a “hugging” sensation
    • May help reduce joint pain and pressure points for lighter individuals
  • Drawbacks:
    • May lack adequate support for back and stomach sleepers
    • Heavier individuals may experience excessive sinkage and misalignment
    • Tends to have a shorter lifespan than firmer mattresses
  • Medium-firm mattresses:
    • A versatile option suitable for a wide range of sleepers
    • Provides a balance of comfort and support, with moderate contouring
    • Ideal for combination sleepers who change positions throughout the night


  • May not be soft enough for some side sleepers, particularly those with joint pain or pressure points
  • May not be firm enough for some back and stomach sleepers, particularly those with higher body weight
  • Firm mattresses:
    • Offers excellent support for back and stomach sleepers, helping maintain proper spinal alignment
    • Provides minimal sinkage, ideal for heavier individuals who require additional support
    • Tends to have a longer lifespan than softer mattresses

  Testing and adjusting mattress firmness

When selecting a mattress, it’s essential to test various firmness levels to determine which is most comfortable and supportive for your needs. Many mattress retailers offer in-store trials, allowing you to lie down on different mattresses and compare their feel.

In addition to in-store testing, consider purchasing a mattress with a sleep trial or adjustable firmness. Sleep trials allow you to test a mattress at home for an extended period (usually 100 nights or more) and return it for a full refund or exchange if it’s not suitable. Adjustable firmness mattresses, such as airbeds or those with removable comfort layers, provide the flexibility to adjust the firmness level to your preference over time.

Understanding mattress firmness and choosing the right level for your needs is crucial for a comfortable and restorative night’s sleep. By considering your sleep position, body weight, personal preferences, and the benefits and drawbacks of various firmness levels, you can make an informed decision and find the ideal mattress to support your sleep needs. Don’t forget to test different firmness levels in-store or take advantage of sleep trials and adjustable firmness options to ensure the best possible sleep experience.
