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.

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.
