Mattress in a Box: How Long to Inflate and What You Need to Know

Ah, the mattress-in-a-box. The Netflix of sleep. The Uber of dreamland. It's fast, convenient, and incredibly comfortable - once it's fully inflated. But that "fully inflated" part can be a little tricky.

How long does it take? And what do you need to do to ensure your mattress reaches its full, cushy potential? Read on, because it's time to sleep better, smarter, and faster.

What is a Mattress in a Box?

First things first, what exactly is a mattress in a box? Despite what you might be imagining, it's not some deflated version of a traditional mattress. It’s a fully-structured mattress compressed and rolled into a compact box for easier shipping and handling.

How to Inflate a Mattress in a Box

Your brand new mattress arrives, all boxed up. Now what? Inflating - or as experts like to say, "decompressing" - your mattress is almost as easy as clicking 'Add to Cart'.

  1. Unbox Carefully: Be cautious while using sharp objects to open the box to avoid damaging your new mattress.
  2. Position It Right: Place the rolled-up mattress on your bed frame and carefully cut open the plastic wrap.
  3. Let It Unroll: Your mattress will start expanding as soon as the plastic is removed, but be patient - it's not done yet.

How Long Does a Mattress in a Box Take to Inflate?

The time it takes for your mattress to fully inflate can vary, but most will reach about 90% inflation within 4-6 hours.

The Final 10%

That last 10%? It can take up to 24-48 hours for some mattresses. If after 72 hours your mattress still doesn’t feel quite right, it may be time to consider reaching out to the manufacturer.

Factors Affecting Inflation Time

Several elements can affect how long it takes for a mattress to inflate. These include:

  • Room Temperature: Cold rooms can slow down the expansion process, as foam expands faster in warmer environments.
  • Mattress Thickness: The thicker the mattress, the longer it might take to expand to its full dimensions.
  • Mattress Type: Hybrids generally take longer to inflate than all-foam models.

What Not to Do While Waiting for Your Mattress to Inflate

While it's inflating, avoid:

  • Sleeping On It: If you sleep on it before it's ready, you might affect the mattress’s structure.
  • Stacking Heavy Objects: This can interfere with the expansion process.
  • Rushing It: Don’t expect it to be a perfect sleep environment instantly. Give it time.


So, in a world where we want everything yesterday, the mattress in a box forces us to exercise a bit of patience. But don't worry, it's worth the wait. When it comes to "mattress in a box: how long to inflate," now you've got the lowdown.
