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.

Emma

Is the Emma Sleep mattress a good investment?

The Emma Sleep mattress is an excellent choice, particularly for those who sleep on their backs. Despite being an all-foam mattress, it offers a perfect blend of comfort and support that back sleepers require. It also provides adequate support for stomach sleepers, which is quite an achievement for an all-foam mattress.

What makes the Emma Mattress unique?

The Emma Original is made with Visco Memory foam, which perfectly conforms to your body shape, providing relief to sensitive pressure points and ensuring spinal alignment. The mattress also has a high-resilience extra foam layer at the bottom that offers additional back support as you sleep.

Why does the Emma mattress feel warm?

The warmth you experience with the Emma mattress is due to its construction from synthetic foam, including memory foam. These materials are known for their heat retention properties. Vasco elastic foams like memory foam respond to, retain, and build up heat to function effectively.
