Frequently Asked Questions


What is the best mattress for all sleep positions?

A high-quality memory foam mattress is often the best mattress choice for all sleep positions. Our BedInABox® mattresses are designed to contour to your body, providing support and pressure relief whether you sleep on your back, side, or stomach.

How long can a 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 time frame so that you do not void the warranty.

How do I clean my mattress cover?

If something has happened to your mattress cover we recommend spot cleaning it with a mild household fabric or upholstery cleaner. The mattress cover is not to be unzipped or removed. Be sure to test a small area first to ensure that the cleaner doesn’t cause any discoloration or damage the fabric in any way. You should also avoid using any thick bristled brushes to scrub the cover as this can cause damage to the fabric as well. We do recommend a waterproof mattress protector to keep your mattress looking great and stain free.

Why is BedInABox® the best Mattress in a Box?

Because we are the only brand that makes our own foam, assembles every mattress and ships it all from our own factory in North Carolina. So not only is every component of your mattress in a box made in America, but your BedInABox® is made under one roof!

Will I need to flip my mattress?

No, BedInABox® mattresses are not constructed to be flipped! However, for a firmer sleep, you can flip your mattress to the support layer side. Should there be a significant weight difference between you and your sleep partner, we do suggest rotating the mattress every six months to prevent uneven wearing and to prolong the life of your mattress.

When can I sleep on my mattress?

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

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, as well. We recommend pairing your BedInABox® mattress with our Clever Connect® foundation or our MotionInABox® Adjustable Frame.
