Open cell structure increases air flow, contributing to a cooler sleep. |

That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body. | The CoolRest® advanced memory foam has been softened (just slightly), creating more contouring qualities, while retaining the same great support. CoolRest® advanced memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning. Sure Align support foam designed to support & correctly align your spine so you can sleep better. This works in tandem with the memory foam and provides perfect support for long lasting comfort and helps to distribute body weight evenly across the mattress. |

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.
BedInABox Original
What sleep setup do you recommend for my BedInABox?
Each BedInABox® mattress is designed to work with any standard foundation. Foam mattresses need as much direct support under them as possible in order to properly support the sleepers. Keeping a slatted or platform foundation under your BedInABox® will help you avoid mattress sagging or breakdown of the memory foam. It is recommended to pair your BedInABox® mattress with the Clever Connect foundation or the MotionInABox™ Adjustable Frame.
Is there a weight limit on your mattresses?
BedInABox® uses high-quality support foam, so there are no weight limits for any of their memory foam mattresses. However, certain foundations do have weight limits. Their foundations are rated for up to 1000 lbs.
Why is BedInABox® the best Mattress in a Box?
BedInABox® claims to be the best Mattress in a Box because they are the only brand that makes their own foam, assembles every mattress, and ships it all from their own factory in North Carolina. This means that every component of your BedInABox® is made in America and under one roof.
