What is a mattress in a box?

A mattress in a box, often a foam mattress comes compressed in a conveniently sized box before shipping. This way, it creates less hassle when shopping and is often more affordable.

Typically, when you open a mattress in a box it will quickly unfurl and start to grow in size once on the bedframe or floor. This is because the mattress has been packed so tightly into a box and requires time to expand. Most mattresses will only take a few minutes to fully expand but others may take a few hours or even days. It's best to consult the instructions that will come with your mattress in a box.



What are some signs that you need a new mattress?

Every case is unique and while some mattresses may last 10 years, others may be perfectly fine for even longer. Here are some of the most common signs it's time to swap out your mattress for something new:

Mattresses typically range from being extra soft, soft, medium, medium firm to firm and extra firm. Choosing a firmness level usually depends on a few different factors which include body weight and sleep positions. Those who are lighter in weight usually find soft to medium mattresses more comfortable, as opposed to those with heavier builds that would typically go for a firmer mattress.
