FAQs

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.

Serta iComfort

How long should a Serta iComfort mattress last?

The Serta iComfort mattresses, made with high-density foams, are expected to last for a minimum of 10 years. Regular rotation of the mattress can help prolong its lifespan.

Is Serta iComfort good for back pain?

The Serta iComfort mattress could be beneficial for those experiencing back pain or discomfort at pressure points. Its carbon fiber memory foam core provides firm yet adaptable support, making it a good choice for back sleepers.

Does Serta iComfort have coils?

Yes, the Serta iComfort mattress does contain coils. The new Smooth Hybrid line features Serta's 100 Series 5-Zone Quad Coil Support System, made with 85% recycled steel, which provides targeted pressure relief and support.
