Molecule 2 vs Serta iComfortECO Foam

On a scale of 10, our mattress has a 6.5 firmness level. We like to refer to it as a "medium firm" - soft at the top, firmer in the middle.

The base model (CF1000) is a medium comfort. Choose the cooling upgrade (CF2000) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000) and Max Cooling & Pressure Relief Upgrades (CF4000) offer a selection of feels - medium, plush, ultra plush and firm, plush, ultra plush.

Each component of the MOLECULE mattress has been engineered to work synergistically to maximize support, comfort and heat dissipation for the best recovery-focused sleep. Featuring a 4 layer construction:

• 1" BioCharge™ layer
• 2" AirTEC™ layer
• 3" RecoveryFLO™ layer (Density: 1.65lbs, ILD: 40)
• 6" ContourFLO™ layer (Density: 1.5lbs, ILD: 35).

With the iComfort by Serta® mattress, cool, supportive sleep is the priority. The base model (CF1000) has these layers:

• Carbon Fiber Memory Foam
• EverCool® Fuze Gel Foam.

Better sleep leads to peak performance. It's not just the quantity of your sleep, it's the quality. Your body restores itself most during Slow Wave Sleep - replenishing blood and oxygen and releasing essential hormones. Sleep scientists and athletes engineered Molecule's unique sleep system so you benefit from the most revitalizing stage of rest, optimizing your body's recovery and performance.

Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available:

• Cooling Upgrade (CF2000): 11.5" Additional cooling and firmer support.
• Max Cooling Upgrade (CF3000): 12.5" Cooler and more breathable.
• Max Cooling & Pressure Relief Upgrade (CF4000): 13.5" Feels and sleeps cooler, with air support layer to take pressure off joints.

The firm base support fosters healthy spine alignment.

Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever.

The most restorative rest happens when your body temperature is cooler. Only Molecule offers this revolutionary airy, extreme open-cell structure for consistent cooling even when compressed by your body weight. Cozy support with more than seven-times the airflow of traditional memory foam. Active people need more support and airflow than traditional egg-crate foam mattresses can deliver.

Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.

Ergonomically-engineered Molecule features a meticulously-engineered matrix of hexagon-shaped channels that respond to your unique anatomy and promote airflow even at the deepest depression points. You awake refreshed with relief from sore muscles and joints. Larger hexagon zones in the center designed for additional support and pressure relief in the lumbar region. Varying hexagon zone density around the legs and feet to support the lower body.

Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
Air Support™ Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.

Cover is 98% Polyester, 2% Lycra. It wicks away heat and moisture to keep skin comfortably cool. As your body temperature changes throughout the night, Molecule's advanced cover material responds dynamically, adjusting evaporation and cooling. Microban® antimicrobial treatment keeps your mattress fresh and clean.
