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.

Zoma Hybrid

Do you need a box spring for a Zoma hybrid?

Zoma advises against using a box spring with its hybrid mattress. Instead, the company recommends using a platform or slatted base, with the slats being no more than three inches apart and at least half an inch thick.

Does Zoma hybrid mattress have fiberglass?

No, Zoma Mattress does not contain fiberglass, contributing to a healthier sleep environment. The mattress also features breathable comfort foams and a fireproof layer for added safety.

What makes the Zoma Hybrid Mattress unique?

The Zoma Hybrid Mattress stands out due to its sleep-enhancing technologies that promote deeper sleep and faster recovery. It features Triangulex™ zoned support for healthy alignment and gel foams for temperature regulation.
