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.

Purple Hybrid

How long does Purple Hybrid last?

Purple mattresses are designed to last approximately 10 years with normal use. Sagging should not occur as long as the mattress is used as intended within its 10-year lifespan.

Is Purple Hybrid good for stomach sleepers?

Yes, the Purple Hybrid Mattress is a good choice for stomach sleepers. It is designed to provide the necessary support for those who prefer this sleeping position.

What happened to Purple Hybrid?

The Purple Hybrid and Premier mattresses have been discontinued and are no longer available for purchase. Purple now offers new hybrid mattresses in their Premium and Luxe collections, including the Purple Hybrid, and the Purple Hybrid Premier 3 and 4.
