FAQs

Siena Memory Foam

What are Siena mattresses made of?

The Siena Memory Foam Mattress is made with a tri-layer design that includes gel-infused memory foam and two different types of polyfoam. The foam used in the mattress is CertiPUR-US certified, meaning it's free from harmful chemicals and additives.

Can you flip the Siena mattress?

The Siena mattress is not designed to be flipped. It has a high-density base foam layer at the bottom, and flipping it would compromise its pressure-relieving properties.

How long will the Siena mattress last?

The Siena mattress, being a budget mattress, is not made with as many high-quality materials and is therefore expected to last about five years. This is approximately half the lifespan of a typical mattress.

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.
