Specifications side by side

LIFEMENT Mattress Lineup Overview

The list ranks two memory foam models by their published specifications. The top pick is the LIFEMENT 12-Inch Full Graphite Memory Foam Mattress. It measures 12 inches thick and weighs 58.4 pounds. This medium-firm profile targets pressure relief. It features CertiPUR-US certification for material safety. The graphite-infused foam aims to manage heat for full-size beds. You get a bed-in-a-box design that arrives compressed. This model suits sleepers who want a standard height and certified materials.

The second option is the LIFEMENT 6 Inch King Cooling Gel Mattress. It stands only 6 inches tall and weighs 54 pounds. The cover uses cooling gel to enhance temperature regulation. It also offers medium-firm support for pressure relief. This lower profile fits King-size frames. It targets shoppers who prefer a thinner mattress. The gel cover provides a distinct cooling surface. Both models prioritize cooling and safety certifications in their construction.

Who LIFEMENT Mattresses Suit

LIFEMENT’s current lineup targets sleepers who need specific cooling or size solutions. The 12-inch Full model offers a standard height for those prioritizing pressure relief and CertiPUR-US safety in a medium-firm feel. The 6-inch King option suits those who prefer a lower profile without sacrificing support. You will not find Queen or Twin sizes here, nor any hybrid or innerspring options. If you need a taller bed or a different firmness level, this brand’s current range may not fit your needs. Stick to these two memory foam picks if cooling and safety certifications matter most to you.

How to choose the right LIFEMENT mattress

1. Check the height for your bed frame

   Mattress height determines how easily you can get in and out of bed. The LIFEMENT 12-Inch Full model offers a standard profile that fits most standard bed frames. If you prefer a lower silhouette, the 6-Inch King option provides a reduced height. A 6-inch thickness may suit platform beds or those who find higher mattresses difficult to climb. Verify your frame’s clearance to ensure proper airflow and stability. Choose the height that matches your mobility needs and existing furniture dimensions.

2. Select firmness for spinal alignment

   Both models in this guide feature a medium-firm feel. This firmness level supports spinal alignment for back and side sleepers. A medium-firm surface prevents excessive sinkage while cushioning pressure points. If you prefer a softer surface, neither option here may be ideal. The consistent firmness across the lineup simplifies the choice if you already know your preference. Focus on how this feel supports your body weight and sleeping position. This spec is critical for long-term comfort and pain reduction.

3. Review certifications for material safety

   Material safety is verified through independent certifications. The 12-Inch Full model carries CertiPUR-US certification. This indicates the foam meets standards for content, emissions, and durability. It ensures the absence of harmful chemicals like formaldehyde or heavy metals. If you prioritize non-toxic sleep environments, this certification is a key decision factor. It provides assurance regarding indoor air quality. Always check the product page for current certification details to confirm safety standards are met for your household.

4. Evaluate cooling features for temperature control

   Temperature regulation is vital for uninterrupted sleep. The 6-Inch King model highlights a cooling gel cover. This feature helps dissipate heat away from the body. The 12-Inch Full model uses graphite in its foam for similar heat management. If you sleep hot, look for these specific cooling technologies. Gel covers and graphite infusions are designed to maintain a cooler surface temperature. Compare these features against your personal sleep temperature needs to prevent night sweats.

5. Consider setup ease and portability

   Both mattresses arrive compressed in a box. This bed-in-a-box format simplifies delivery and setup. You can roll or slide the package through narrow doorways. Once unpacked, the foam expands to its full dimensions. This special feature is useful for upper-floor apartments or homes with limited access. The 12-Inch model weighs 58.4 pounds, while the 6-Inch King weighs 54 pounds. Consider the weight if you need to move the mattress into place yourself after unboxing.
