Frequently Asked Questions

How does the Tranquillium® mattress feel?

The BedInABox® Tranquillium® mattress is a firm 12” all foam construction, featuring our CoolRest® Gel Foam comfort layer, a Pluralux® Foam transition layer and a Sure Align™Foam support layer. The transition layer helps maintain the cushioning of the comfort layer while slowly building support.

Which foundations are compatible with the Tranquillium® mattress?

BedInABox® mattresses are designed to be paired with any standard solid or slatted foundations for adequate support.

How does the Tranquillium® compare to other brands?

Unlike many other mattress-in-a-box brands who outsource materials and manufacturing, BedInABox® manufactures all of our mattresses in the United States. We oversee every component of the process, from foam pouring to shipping, to ensure our customer’s satisfaction.

Is the Tranquillium® CertiPUR-US® certified?

Yes, all BedInABox® mattresses are CertiPUR-US® certified. This means that the foams used to build the Original mattress have been tested for content, emissions, and durability by accredited laboratories and are certified free from a number of potentially hazardous compounds. This certification ensures that your mattress is safe for the consumer and the environment.

What benefits does the CoolRest® layer offer?

The CoolRest® comfort layer is infused with CoolRest® technology to keep you from sleeping hot while providing the perfect level of contour for that “hugging” sensation.

What is the Sure Align™ Foam in BedInABox® mattresses?

Sure Align™ is the firm support foam used in every BedInABox® mattress. It is designed to provide the perfect level of support and alignment for your spine.

What is a mattress in a box?

A BedInABox® mattress in a box is a high-quality memory foam mattress that is compressed and rolled into a box before shipping. We developed the technology to compress and roll mattresses in 2006, so that the mattress shopping and delivery process could be simplified by eliminating the need for in-store visits and traditional mattress delivery. We offer mattress in a box options in all standard mattress sizes and in firmness levels that support every sleep need.

How long can my mattress stay in the box?

Your BedInABox® mattress should be unboxed upon arrival. However, if you need to wait to unbox your new bed, it can remain roll-packed and boxed for no longer than 30 days. We ask that you unbox within this timeframe so that you do not void the warranty.

When can I sleep on my mattress in a box?

Your mattress is ready to go to bed when you are. BedInABox® mattresses are ready to use within minutes of opening.

Will I need to flip my mattress?

No, BedInABox® mattresses are not designed to be flipped. We do suggest rotating your BedInABox® every six months to prevent uneven wear and to prolong the life of your mattress.
