Molecule 2 vs Leesa Sapira Hybrid

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.

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).

Formerly known as the Sapira Hybrid, the Leesa Hybrid is a 5-Layer Construction:

• 1.5" Cooling Premium Foam Top Layer (IFD: 20. DENSITY: 3.65 PCF)
• 1.5" Contouring Memory Foam (IFD: 9. DENSITY: 4 PCF)
• 1" Core Support Foam Base (IFD: 32. DENSITY: 1.8 PCF)
• 6" Quantum core pocket coil system (14.5 gauge)
• 1" Core Support Foam Base (IFD: 32. DENSITY: 1.8 PCF)
• Seamless Iconic Four-stripe Cover.

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.

The Leesa Hybrid mattress combines Leesa's premium cooling and pressure-relieving foams with an advanced pocket spring system that actively responds to your body's pressure points throughout the night. As your body presses into the mattress, Leesa Hybrid's individually-wrapped coils gently push back, providing unparalleled support, edge to edge.

The firm base support fosters healthy spine alignment.

The Secret is in the Springs
Our pocket-springs were created after many hours of prototyping to find the perfect gauge wire that gives superior edge support. Once perfected, the coils are encased and placed between layers of foam for the perfect fusion of pocket springs and high performance foam.

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.

Cooling Premium Foam
The 1.5" top layer is a high performance 3.75 lb high density foam. This performance layer does not retain heat, is hole-punched to allow airflow cooling, and provides enough bounce for freedom of movement.

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.

Pressure-relieving Memory Foam
The 1.5" memory foam layer delivers the body contouring and pressure relief you've come to expect from memory foam.
Supportive Springs
Premium grade steel springs nestled between two layers of 1" stabilizing foam provide a unique core support layer.

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.

A single knitted length of fabric (made in the USA) is beautifully tailored to hug the mattress and your body. Subtle quilting and our signature "patterns" of life stripes add to the elegance and comfort.

Our deliveries are exclusively handled by FedEx, and you should expect your mattress within one week from when you place your order.
