Mattress Firmness

Firmness of a mattress varies across different mattresses. What might seem soft to one individual could feel firm to another. Regardless of personal perception, a mattress should effectively support body weight, encourage proper spine alignment, and provide a comfortable and rejuvenating sleep experience. The categorization of a mattress as soft, plush, or firm is entirely determined by individual preferences, choices, and body characteristics.

Firmness of Molecule 1 Mattress

Molecule 1 is classified as a medium-firm mattress, ranking at 6 on the industry-standard firmness scale of 1 to 10. When lying on your back, you may initially experience a gentle sinking sensation into the comfortable top layer. However, rest assured that the mattress’s foundation delivers ample support, ensuring proper alignment of your hips and spine.

The strategically designed zoned support system caters to the specific needs of your back, hips, and shoulders. This mattress achieves its softer feel through a combination of a plush top comfort layer, a firmer transitional layer, and a supportive base layer beneath.

Material & Construction

Q1. What Are The Unique Technology, Design, And Materials Used In The Construction Of Molecule 1 Mattress?

Molecule 1 is a foam mattress constructed with layers of memory foam and polyfoam, thus making the brand a 100% polyurethane foam mattress. The mattress cover is 98% polyester and 2% lycra. The temperature-sensitive surface adjusts according to the body temperature of different sleepers, thus taking away heat and moisture.

The cover is breathable, soft, and very comfortable. The cover is an addition to the overall luxurious feel of the mattress.

The foams used in the construction of the mattress are eco-friendly, which helps to reduce emissions. The mattress is CertiPUR-US certified, implying low VOCs, without using heavy metals or harmful chemicals.

This mattress is designed to aid the body’s recovery after a heavy workout and advocates restful sleep. Given below is a detailed Molecule mattress review of the construction of Molecule 1 Mattress. The mattress is constructed in three different layers using foams of different densities, the detail of which is below:

  • Cover: The innovative cover of Molecule 1 mattress employs a distinctive blend of heat and moisture-wicking technologies, creating a balanced microclimate between your body and the sleeping surface. Utilizing MOLECULEshield™ treatment effectively inhibits the proliferation of odor and stain-causing bacteria, ensuring a more hygienic sleep experience.
  • Layer 1:The comfort layer of the Molecule 1 mattress features the brand’s proprietary memory foam known as the RESTOREFLO™. This layer has an open-cell structure to allow for greater airflow within the mattress. It is also infused with gel beads to wick away heat.
  • Layer 2:It is a thick polyfoam layer with a zoned construction to provide comfort. This foam blend, called RECOVERYFLO™, is a response layer that gives targeted support and contouring. This layer is softer near the head and feet and firm near the center. The zoned construction provides pressure relief to the sleepers, with proper support in the lumbar region.
  • Layer 3: This layer consists of 7 inches of firm polyfoam that is breathable CONTOURFLO™ foam that supports the mattress to offer spinal alignment. This breathable layer also dissipates heat and enables one to sleep cool. This layer is the foundation for the layers above. It helps to retain shape and extends the longevity of the mattress.

Q1. How would you rate Molecule 1 Mattress from a repositioning & responsiveness perspective? 


Repositioning means that sleepers can change position easily. The Molecule 1, a memory foam mattress, helps relieve pressure but restricts movement. Because of the two-inch comfortable memory foam layer, sleepers sink into the mattress, thus making changing positions harder.

The qualities of Molecule 1 offer excellent motion isolation and can also make sleepers feel stuck in the mattress. The foam layer returns to its original shape slowly, and there is minimal bounce to the mattress.


Responsiveness refers to how well your mattress adapts to your body’s weight and movements. Improved responsiveness leads to quicker shape recovery, making it easier to change sleeping positions without feeling stuck in the mattress.

Molecule 1 features foam that offers excellent responsiveness, allowing individuals to move freely on the mattress without experiencing any significant impediments. It provides pressure relief without the sensation of being trapped.

Comfort, Back Support, Pressure Relief


Q2. How would you rate Molecule 1 Mattress for providing comfort and pressure relief to sleepers? 

Most of us are unaware that our spine is responsible for most of our movements as it connects all the major muscles responsible for movements. Back pain is a common problem that impacts our daily lives and disrupts our sleep. Chronic back pain results in poor sleep, which can be very frustrating as it makes one feel significantly worse during waking hours.

Chronic back pain may sometimes be challenging to find a comfortable sleeping position. Thus, it is essential to understand that different sleeping positions require different cushioning, contouring, and mattress firmness levels to avoid worsening back pain.

Molecule Mattress product, Molecule 1, is believed to relieve discomfort, thus providing enough back support to those who weigh less than 230 pounds. For the spine to be appropriately aligned, back sleepers need lumbar support. Firm support is provided by the zoned layer of Molecule 1 for the lower back, with the memory foam layer giving pressure relief.

With the zoned construction, one shall feel soft near the shoulders and hips while getting ample support near the lumbar area. The mattress does not let one sink in uncomfortably and promotes spinal alignment. Thus, the Molecule 1 mattress performs excellently in providing pressure relief.

The mattress is a great choice for back and side sleepers and those weighing less than 230 pounds. Stomach sleepers more than 230 pounds may sink into the mattress more, thus putting pressure on the lower back.

Cooling & Temperature Control


Q3. How would you rate the cooling and overall temperature control characteristics of the Molecule 1 Mattress?

The most critical condition that determines the quality and duration of the body’s recovery during sleep is an adequate decrease in the core body temperature. As we sleep, the thermoregulation of our body is not proactive enough, so other factors that can control the temperature of the body can be the products that we use to sleep on becomes essential.

Molecule 1 dissipates heat and regulates temperature more effectively than other memory foam mattresses. The fabric covered with temperature-sensitive polymer helps to keep away heat and moisture. The gel-infused comfort layers have an open-cell construction that allows for greater airflow. Thus, one does not have to sleep hot and sweaty with the cooling features of the Molecule 1 mattress.

Motion Isolation and Sharing a Bed


Q4. Does Molecule 1 Mattress provide reasonable motion isolation when sharing a bed with others?

The Molecule 1 mattress from Molecule Mattress brand offers excellent motion isolation. The mattress is at par with other foam mattresses mainly due to its comfort system. The dense foam layers absorb motion transfer and prevent you from feeling any movement when your partner makes position changes. This makes the Molecule 1 mattress a good fit for those who do not wish to get disturbed while sleeping with their partners.

Edge Support


Q5. How would you rate the edge support of Molecule 1 Mattress?

Molecule 1 mattress does not perform as well in providing strong edge support. The foam layers get compressed near the edges when pressure is applied. Though the firm polyfoam support core tries to make up for it, you may feel some sinkage while sitting or lying near the edges. The lack of strong edge support is important for those who find it difficult to get in and out of bed.

Recommendation based on sleeping style

Every individual possesses distinct sleeping needs, which are influenced by factors like their weight, height, and preferred sleeping position. Regardless of the position we choose to sleep in, it is crucial for all of us to ensure that we get quality rest to enable our bodies to heal and revitalize. Sleep focused on recovery is especially vital for individuals leading highly active lives and engaging in intense workouts.

There are essentially three primary sleep postures: side sleeping, back sleeping, and stomach sleeping. Consequently, each of these positions entails distinct requirements and unique preferences when it comes to mattress comfort, support, and flexibility. Additionally, there are individuals who are combination sleepers, and they enjoy shifting positions throughout their sleep.

This Molecule mattress review provides insight into the adaptability of Molecule 1 Mattress across different sleeping postures.

Molecule 1 Mattress and Side Sleepers

  • Molecule 1 Mattress offers generous cushioning to support the shoulders and hips, making it an ideal choice for side sleepers. Its specially designed foam layers provide the perfect balance, allowing the shoulders and hips to sink in just the right amount while maintaining proper spinal alignment. Individuals with body weights ranging from 130 to 230 pounds will experience the most advantages from this mattress.

Molecule 1 Mattress and Back Sleepers

  • The National Sleep Foundation recommends that the optimal sleeping position is lying on your back with your arms resting at your sides. This sleeping posture promotes a neutral alignment of the head and spine, reducing the pressure that can lead to discomfort. It enables the relaxation of the muscles in the back. Back sleeping is particularly advantageous for individuals experiencing back pain or stiffness.
  • This mattress is ideal for individuals who predominantly sleep on their backs and have a light to average body weight, weighing less than 230 pounds. It provides excellent support and cushioning for them. Nevertheless, if you’re a back sleeper with a body weight exceeding 230 pounds, you might perceive Molecule 1 as somewhat too soft.

Molecule 1 Mattress and Stomach Sleepers

  • Sleeping on the stomach can challenge the spine’s natural alignment, but it may be beneficial for individuals who snore. Those who favor stomach sleeping exert more pressure on the mattress, particularly in the midsection area. Therefore, an ideal mattress choice would be one that offers robust support to prevent sinking and potential spinal issues.
  • Molecule 1 mattress offers excellent support for lightweight stomach sleepers who weigh under 130 pounds. Its high-density foam layers effectively maintain spinal alignment while ensuring a comfortable sleep experience. However, individuals weighing over 130 pounds might not experience the same level of support with this mattress.
