Frequently Asked Mattress in a Box Questions

Need a new mattress? You’re in the right place! At Ashley, we carry a wide selection of top-quality mattresses and beds to suit virtually any bedroom style and sleeping preference. No matter what size or material you’re looking for, we can help you find the mattress of your dreams.

Do Mattresses in a Box Last?

The longevity of an Ashley Sleep mattress in a box depends largely on the materials the mattress is fashioned from and the quality of the product. Generally, however, the expected lifespan of a mattress that comes in a box is about the same as a mattress that doesn’t come in a box. Both types of mattresses should last approximately seven to 10 years.

Are Mattresses in a Box Memory Foam?

Memory foam mattresses are the most common type of mattress in a box, but boxed mattresses are also available in other materials.

What Is a Mattress in a Box Made Of?

Mattresses in a box are generally made of polyester or polyurethane memory foam, gel memory foam, or latex foam. Some are fashioned from a single type of foam, while others are hybrids that feature a combination of foam types and supportive inner springs.

How Long to Wait Before Sleeping on a Mattress in a Box?

The length of time you should wait before sleeping on a new mattress in a box depends on the type of mattress you get. Lower-profile mattresses generally take less time to expand to their full shape, while thicker mattresses usually take longer. Your new mattress should come with directions outlining the length of time expansion typically takes.

Is It OK to Sleep on a Memory Foam Mattress Before 24 Hours?

Although most mattress-in-a-box directions recommend waiting at least 24 hours after unboxing to use your new mattress, that’s not a hard-and-fast rule. It’s OK to sit on your mattress or even sleep on it before 24 hours have passed — doing so won’t damage it in the slightest. Just know that your new mattress may not feel its best until it expands to its full size.

What Types of Mattresses Are Mattress in a Box?

A mattress that comes in a box may be memory foam, gel memory foam, or dense latex foam. Hybrid mattresses in a box are also available, which feature a combination of gel, latex, or memory foam and inner coils that provide additional support.

How Long Does a Bed in a Box Take to Expand?

Some mattresses are ready to go within a few hours after unboxing, and others need up to 48 hours to expand completely.
