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.

Bear

Do Bear mattresses last?

Like the average memory foam mattress, you should expect to get at least eight to 10 years out of your Bear mattress.

Are Bear mattresses hot?

In comparison to other all-foam mattresses, the Bear does maintain good temperature neutrality and doesn't get too hot.

Where is Bear Mattress from?

Bear mattresses are proudly made in America.
