Comfort	Siena means comfort. Comfort that helps you forget about the worries of the day. Comfort that tells your body, “relax, it’s time to recharge”. Comfort that helps you enjoy a long, deep, and soul nourishing sleep.	A naturally eco-friendly and sustainable resource, wool works to wick moisture and disperse your body heat, keeping you cool in the summer and warm in the winter. Plus, it’s naturally fire-resistant—so there’s no need for added chemicals or toxins.
Support	Some people love super soft mattresses. Some people love a rock hard one. Most people are somewhere in the middle. That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body.	The GhostBed Natural features two all-natural latex types, Talalay and Dunlap. Breathable, comfortable and extremely durable, Dunlop latex is truly the cream of the crop… while Talalay latex is supportive yet pillowy soft, contributing to the super-comfortable feel.

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.

GhostBed Natural

What makes Ghostbed unique?

GhostBed is created by experienced mattress professionals with decades of experience. It is designed to provide optimal comfort for all types of sleepers. Additionally, its gel memory foam and aerated latex foam interior help to dissipate heat, keeping you cool throughout the night.

Where is the Ghostbed Classic made?

GhostBed mattresses are proudly manufactured in the United States, ensuring high quality and fast delivery from various shipping locations across the country.

Do Ghostbed mattresses smell?

Similar to other high-end memory foam products, a slight smell may be noticed upon unboxing the mattress. This smell, comparable to a new pack of tennis balls or a new car, is normal and harmless, and will dissipate over time.
