It is no secret that getting a good night’s sleep is vital for overall health and well-being. Choosing the right mattress firmness for side sleepers is vital to ensure a comfortable and restful sleep. In this article, we will explore the different levels of mattress firmness and help you understand which one is best suited for side sleepers. From the benefits of softer mattresses to the advantages of firmer ones, we will cover everything you need to know to make an informed decision. So, let’s dive in and find out the best mattress firmness for side sleepers.

The importance of mattress firmness for side sleepers

For side sleepers, the firmness of their mattress plays an important role in providing the right level of support and comfort. Unlike those who sleep on their back or stomachs, side sleepers place increased pressure on their hips and shoulders. This can result in discomfort and shoulder pain if the mattress lacks adequate support. The right mattress firmness helps align the spine properly and allows the body to sink in just enough to relieve pressure points. It also helps prevent any misalignment that can result in aches and pains. Therefore, choosing the best mattress firmness is essential for side sleepers to ensure a good night’s sleep and a refreshed wake-up.

Understanding Mattress Firmness

What exactly is mattress firmness? Firmness refers to the initial feel you experience when lying on a mattress. It is determined by factors such as sinkage, contouring, and pushback. 

Now, let’s take a closer look at each level of firmness and which sleepers may benefit from them. The mattress industry employs a scale from 1 to 10 to describe how firm a mattress is, helping consumers understand its texture. A rating of 1 indicates the softest mattress, while a rating of 10 denotes the firmest. The industry’s typical standard for medium firmness is around 6.5 out of 10.

Soft Mattresses

They provide deep sinkage, body contouring, and pressure relief. These soft mattresses are often preferred by strict side sleepers or those in need of extra comfort at the shoulders, hips, and lower back.

Medium-Firm Mattresses

Medium-firm mattresses typically score around 6.5 out of 10 on the firmness scale. They achieve a balance between relieving pressure and providing support, which renders them suitable for a broad spectrum of sleepers. Combination sleepers and back sleepers may find medium-firm mattresses particularly comfortable.

Firm Mattresses

Firm mattresses usually score 7 out of 10 or higher on the firmness scale. They offer minimal sinkage and maximum support. Strict stomach sleepers and heavier individuals may appreciate the extra lift and support of firm mattresses.

Understanding the Firmness Scale

Now that we’ve discussed the different levels of firmness, let’s take a closer look at the entire firmness scale to understand better what each score represents. Remember that these interpretations are subjective, but they provide valuable insights into how different firmness levels translate into real-life comfort.

  • 1 out of 10, or extremely soft: A mattress scoring 1 out of 10 would offer excessive sinkage and lack of support. It is rare to find a mattress that is a true 1 out of 10 on the firmness scale.
  • 2 out of 10, or ultra-soft: A mattress with a firmness score of two on the scale would still lack support for most sleepers, although it would be marginally more realistic than a mattress rated 1 out of 10.
  • 3 out of 10, or very soft: Mattresses scoring 3 out of 10 starts to provide more support while still offering sinkage. Soft mattresses in this range are typically made of memory foam, known for deep pressure relief.
  • 4 to 5 out of 10, or soft: Mattresses scoring 4 to 5 on the firmness scale are soft but have a more balanced feel. Sleepers will experience less of a “stuck-in-the-bed” sensation than with softer mattresses.
  • 6 out of 10, or medium-soft: This score represents a common firmness level for many bed-in-a-box mattresses described as “soft.” They combine plush comfort layers with a supportive base.
  • 6.5 out of 10, or medium-firm: A true medium-firm mattress with a balance between pressure relief and support. Many mattresses on the market fall into this firmness range.
  • 7 out of 10, or slightly firm: Mattresses scoring seven on the firmness scale provide lift and support, making them suitable for combo sleepers, back sleepers, and stomach sleepers.
  • 8 out of 10, or firm: Mattresses scoring 8 out of 10 are very firm and offer minimal body contouring. These beds are great for back and stomach sleepers.
  • 9 out of 10, or very firm: Similar to an 8 out of 10, mattresses scoring 9 out of 10 provide even less hug and sinkage. They are particularly suitable for heavier sleepers.
  • 10 out of 10, or ultra-firm: It is extremely rare to find a true 10 out of 10 mattress, as they offer no pressure relief.

Factors to consider when picking the best mattress firmness for side sleepers

When selecting the best mattress firmness for side sleepers, it is crucial to consider several factors. Here are some key points to keep in mind:

  1. Body weight: Side sleepers with lighter body weights may find softer mattresses more comfortable, while those with heavier body weights might prefer a firmer mattress for better support.
  2. Pressure points: Consider any specific pressure points or problem areas you may have. Softer mattresses are better at relieving pressure points, while firmer mattresses provide more support.
  3. Personal preference: It comes down to personal preference. Some side sleepers may find a softer mattress more comfortable, while others may prefer a firmer feel. It is essential to test different firmness levels to find your ideal fit.
  4. Mattress materials: The firmness of a mattress can also be influenced by the materials used in its construction. Memory foam mattresses offer a more contouring and softer feel, while traditional innerspring mattresses are generally firmer.
  5. Motion isolation: When sharing your bed with a partner, consider the mattress’s capability to minimize motion transfer. Softer mattresses often excel in minimizing motion transfer, ensuring a disturbance-free sleep.

By taking these factors into consideration, you can narrow down your choices and discover the ideal mattress firmness that meets your particular requirements as a side sleeper.

Finding the Best Firmness for Your Sleep Position

The best firmness level for your mattress depends on your sleep position. Let’s take a closer look at the recommendations for each position:

Back Sleepers

Back sleepers need a mattress that offers a balance between support and comfort. A medium-firm mattress is typically recommended for back sleepers, as it lifts the spine into a neutral alignment, alleviating pressure and pain. Hybrid mattresses combine foam and coil layers and are often the best choice for back sleepers.

Side Sleepers

Side sleepers require a soft mattress that delivers substantial pressure relief at the shoulders, hips, and lower back. A mattress with zoned support, softer at the shoulders and firmer at the hips, can provide the necessary comfort and spinal alignment. Memory foam mattresses or those with plush top foam layers are ideal for side sleepers.

Stomach Sleepers

Stomach sleepers need a firm mattress that avoids excessive sinkage and maintains proper spinal alignment. A mattress with a thin pillow top layer on top of a supportive core is recommended for stomach sleepers. Innerspring or hybrid mattresses can provide the necessary support and comfort.

Soft vs. medium vs. firm mattresses for side sleepers

Now, let’s explore the advantages of different firmness levels of mattresses for those who sleep on their side.

Benefits of a softer mattress for side sleepers

Soft mattresses offer several advantages for side sleepers:

  1. Pressure relief: A softer mattress surface enables the body to sink in, alleviating pressure points and lowering the likelihood of waking up with aches and pains.
  2. Spinal alignment: Soft mattresses contour to the body’s curves, promoting proper spinal alignment and reducing strain on the back.
  3. Enhanced comfort: Side sleepers who prefer a plush and cozy feel will find softer mattresses more comfortable, especially if they enjoy the sensation of being cradled by their bed.

Benefits of a medium-firm mattress for side sleepers

Medium-firm mattresses achieve a balance between softness and support, which is why many side sleepers favor them. Here are the benefits they offer:

  1. Optimal support: Medium-firm mattresses provide adequate support to keep the spine aligned while still offering some contouring for pressure relief.
  2. Versatility: These mattresses are suitable for a wide range of body weights and sleeping preferences, making them a versatile option for side sleepers.
  3. Balanced comfort: A medium-firm mattress offers a comfortable sleep surface without sinking too deeply, allowing for easier movement during sleep.

Benefits of a firmer mattress for side sleepers

While not as common among side sleepers, some individuals prefer a firmer mattress. Here are the benefits they provide:

  1. Superior support: Firm mattresses provide robust support, helping to maintain proper spinal alignment and preventing sagging.
  2. Reduced sinking feeling: For side sleepers who do not enjoy the sinking feeling of softer mattresses, a firmer sleep surface can offer a more stable and supportive experience.
  3. Longevity: Firmer mattresses are more durable and have a longer lifespan than softer ones.

Is Firmness the Same as Support?

It is important to understand that firmness and support are not the same. Firmness describes the initial sensation of the mattress, whereas support pertains to how effectively it maintains the alignment of your spine. A soft mattress can still offer excellent support, and a firm mattress may lack support. It is crucial to consider both factors when choosing a mattress.

Finding the right balance: choosing the ideal mattress firmness for side sleepers.

Selecting the ideal mattress firmness for side sleepers requires searching for the right balance between comfort and support. While personal preference plays a significant role, it is crucial to consider your body weight, pressure points, and any specific needs or preferences you may have. It is recommended to test different firmness levels before making a decision.

Many mattress retailers offer trial periods, allowing you to sleep on the mattress for a designated period and determine if it suits your needs. By considering these factors and trying out various options, you can discover the ideal mattress firmness that guarantees a peaceful and revitalizing sleep every night.

Tips for testing and selecting the best mattress firmness for side sleepers

When testing and selecting the best mattress firmness for side sleepers, here are some helpful tips to keep in mind:

  1. Visit a mattress showroom: Visit a mattress showroom to test different firmness levels and get a feel for what suits you best. Lie down in your preferred sleeping position and spend a few minutes on each mattress to assess its comfort and support.
  2. Use trial periods: Take advantage of trial periods offered by mattress retailers. Most reputable brands allow you to sleep on the mattress for a specific period, usually 30 to 100 nights, to ensure it meets your expectations.
  3. Seek expert advice: Seek advice from mattress experts or professionals who can offer guidance tailored to your individual needs and preferences. Their valuable insights and recommendations can help you make informed decisions.
  4. Read customer reviews: Read customer testimonials to gather feedback from other side sleepers who have purchased mattresses. Their experiences can give you a better understanding of how different firmness levels perform in real-life scenarios.
  5. Consider adjustable mattresses: If you have a partner with different firmness preferences or if your preferences change over time, consider an adjustable mattress that allows you to customize the firmness level on each side.

By following these tips, you can make a well-informed decision and select the best mattress firmness for side sleepers that guarantees a comfortable and supportive sleep experience.
