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.	Our 7-layer hybrid mattress fuses the springy support of individually-wrapped coils with the plush comfort of gel memory foam. Experience out-of-this-world comfort, with the best of both worlds. Two one inch layers of special gel-infused Memory Foam absorbs and dissipates body heat as fresh air passes through the foam.
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 core of the GhostBed Flex features the patented Ghost Flex innerspring coil unit with our Spirited Edge Support design. Individual 8.5" coils create the weightless feeling you love, while wrapping them individually creates minimal motion transfer. Plus, two rows of specially reinforced coils along the edge of the bed make it easy to sit comfortably without slipping off. One inch of Ghost Flex Soft Transition Foam offers pure pressure relief. This layer of soft transition foam contours to your body and reduces the need to toss and turn. Individual coils offer the responsive support of traditional innerspring mattresses, without the worry of wearing out after just a few months. Additionally, the coils near the edge of GhostBed Flex are specially reinforced for better support - so you can sit on the edge of your bed without sliding off.

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 Flex Hybrid

How thick is a GhostBed Flex mattress?

The GhostBed Flex mattress is 13 inches thick, which is more than the average mattress thickness of 10 to 11 inches. This extra thickness contributes to the mattress's comfort, support, and durability.

How long does it take for a GhostBed Flex to expand?

You can sleep on your new GhostBed mattress almost immediately, but it can take anywhere from a few hours to a full day for the mattress to expand completely.

Is there a weight limit for the Ghostbed Flex?

The GhostBed Flex can support up to 750 lbs. when placed on a strong foundation. For customers over 300 pounds, it is recommended to purchase the King GhostBed Luxe and the companion King GhostBed All-In-One Foundation.
