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.

Helix Midnight Luxe

Is the Helix Midnight Luxe worth it?

The Helix Midnight Luxe is recommended, especially for couples, due to its memory foam layers that minimize disturbance from a partner's movements. It's less firm than the original Midnight, making it more suitable for side sleepers.

Is Helix Midnight Luxe too soft?

The Helix Midnight Luxe, a hybrid mattress, is rated 6-7 out of 10 on the firmness scale, indicating medium firmness. It should be suitable for most people, providing both pressure relief and support through its combination of foam layers and coil unit.

How thick is the Helix Midnight Luxe mattress?

The Helix Midnight Luxe has a thickness of 14 inches.
