FAQs

MOLECULE 1

What firmness is Molecule 1 mattress?

The Molecule 1 mattress has a medium firmness, rated as a 6 out of 10 on the firmness scale.

Is Molecule mattress safe?

Yes, the Molecule mattress is safe. The foams used are CertiPUR-US certified, meaning they're free of certain harsh metals and chemicals.

Is Molecule 1 or 2 better?

Both Molecule mattress models are constructed with proprietary foam layers. The Molecule 1 is more affordable, while the Molecule 2 offers more zoned support and a comfort layer with improved airflow.

Helix Dusk

Do your mattresses offer different levels of support?

Any strong and solid base is suitable, including adjustable bases. Avoid slatted foundations with gaps of more than 3" and box springs with actual springs. While a slatted base can improve breathability, it's not required as the latex foam in the mattress is naturally breathable. A slatted base can help prevent mold on the mattress cover in high-humidity environments.

What is the lifespan of the Helix Dusk mattress?

The Helix Dusk mattress is designed to last between seven to ten years, with a warranty protecting against premature sagging and manufacturing defects for ten years after purchase. The Helix Dusk Luxe variant offers an extended warranty of 15 years.

Is the Helix Dusk a soft mattress?

The Helix Dusk is not considered distinctly soft. It is a medium-firm mattress with two foam layers providing cushioning, but overall, it has a balanced feel rather than a plush one.
