Understanding the Firmness Scale System

The firmness scale, typically ranging from 1 to 10, serves as a universal benchmark to help consumers gauge the feel of a mattress. Here’s a more detailed breakdown of each firmness level:

Soft (1-3)

Description: These mattresses offer a plush and cushiony feel, allowing your body to sink into the surface. They are excellent for side sleepers who need relief for pressure points like shoulders and hips.

Ideal Sleepers: Side sleepers, individuals with joint pain, or those who enjoy a cloud-like sleeping experience.

Medium-Soft (4-6):

Description: This range strikes a balance between support and softness. It provides a comfortable feel without sacrificing spinal alignment, making it suitable for a variety of sleeping positions.

Ideal Sleepers: Combination sleepers, individuals who switch positions during the night, and those seeking a versatile mattress.

Medium (5-7):

Description: The goldilocks zone of mattress firmness, offering a harmonious blend of support and comfort. It caters to a broad audience, accommodating various sleeping preferences.

Ideal Sleepers: Couples with different sleep preferences, people who change positions frequently, and those who want a mattress suitable for multiple sleeping styles.

Medium-Firm (6-8):

Description: Stepping into the firmer territory, medium-firm mattresses provide additional support, making them suitable for back sleepers. They maintain a degree of softness for overall comfort.

Ideal Sleepers: Back sleepers, individuals with back pain, and those who prefer a supportive yet comfortable surface.

Firm (8-10):

Description: Firm mattresses provide maximum support with minimal sinkage. They are designed for stomach sleepers and those who require robust spine alignment.

Ideal Sleepers: Stomach sleepers, individuals with back issues, and those who prefer a mattress with a solid, supportive feel.

How to Measure Mattress Firmness

Determining mattress firmness involves methods like the indentation load deflection (ILD) test. ILD measures the force required to compress a mattress by a certain percentage. The higher the ILD, the firmer the mattress. This objective measurement helps consumers understand the degree of support a mattress can provide.

Factors Influencing Mattress Firmness

Several factors influence the choice of mattress firmness:

Body Weight

Lighter individuals may find softer mattresses more comfortable, while heavier individuals might lean towards firmer options for additional support.

Sleeping Position

Side sleepers typically prefer softer mattresses for better pressure relief, while back and stomach sleepers may opt for medium-firm to firm mattresses for spine alignment.

Personal Preference

Ultimately, personal comfort preferences play a significant role. Some may prefer the luxurious feel of a soft mattress, while others may prioritize the support of a firm one.

Different Types of Mattresses and Their Firmness

Different mattress types offer varying firmness options:

Innerspring Mattresses

Known for a firmer feel due to the coil support system.

Memory Foam Mattresses

Vary in firmness but often provide a medium to medium-firm feel, contouring to the body’s shape.

Latex Mattresses

Durable and available in various firmness levels, catering to different sleep preferences.

Hybrid Mattresses

Combine materials for a range of firmness options, blending the support of coils with the comfort of foam or latex.

Tips for Choosing the Right Firmness

Choosing the right firmness involves practical considerations:

Trial Periods

Look for mattresses with trial periods and generous return policies to ensure satisfaction.

In-Store Testing

Whenever possible, try out mattresses in-store to gauge personal comfort.

Consider Individual Needs

Take into account individual sleep preferences, health conditions, and partner preferences when selecting firmness.


It’s crucial to note that individual preferences play a significant role in choosing the right firmness level. What might be perfect for one person could be uncomfortable for another. Factors such as body weight, sleeping position, and personal comfort preferences all contribute to finding the optimal firmness for a restful night’s sleep.

When shopping for a mattress, don’t hesitate to inquire about the firmness level and utilize trial periods to ensure the chosen mattress aligns with your individual comfort needs. By understanding the nuances of the firmness scale system, you empower yourself to make an informed decision that positively impacts the quality of your sleep.
