How Long Does It Take for an EGOHOME Mattress to Fully Expand?

If you’ve just unboxed your new bed-in-a-box, you might be asking: How long for EGOHOME mattress to expand? Understanding the expansion timeline and how to properly set it up is key to unlocking its full comfort and performance.

Let’s break down what to expect and how to get the most out of your EGOHOME memory foam mattress.

What Happens When You Unbox an EGOHOME Mattress?

EGOHOME mattresses come compressed and vacuum-sealed to allow for convenient delivery. Once unboxed and unrolled, the mattress begins expanding within moments. The process involves:

• The mattress inflating as it takes in air

• Memory foam layers gradually decompressing

• A soft initial rise followed by a firmer structure as it settles

Make sure to place it on a flat, ventilated surface and remove all plastic layers completely.

How Long for EGOHOME Mattress to Expand Fully?

On average, it takes 24 to 72 hours for your EGOHOME mattress to fully expand. However:

• Initial usable form: within 4 hours, most users can sleep on it that night

• Full height and performance: up to 72 hours, depending on room temperature and mattress thickness (e.g. 12" vs 14")

💡 Tip: A warm room (above 68°F / 20°C) speeds up expansion. Cold rooms slow the process.

Can You Sleep on an EGOHOME Mattress Right Away?

Yes, you can sleep on the mattress within hours of opening. However, it's best to allow:

• Full expansion for optimal support and pressure relief

• Initial off-gassing (minor foam odor) to dissipate

If comfort feels uneven or the height isn't fully restored, wait another day.

Signs That Your Mattress Has Fully Expanded

Wondering if your mattress is ready? Look for:

• Mattress height matches its labeled thickness (e.g., 12" or 14")

• Surface is flat and even

• No lingering creases or indentations

• Firmness has stabilized

Troubleshooting: What If the Mattress Doesn’t Expand?

Sometimes, the mattress may take longer due to:

• Cold temperatures slowing foam recovery

• Incomplete unwrapping or folded corners

• Placing the mattress on a non-ventilated or soft surface

If it’s been over 72 hours with no significant change:

• Double-check all packaging has been removed

• Place the mattress in a warm, dry space

• Contact EGOHOME customer support for guidance

Fortunately, such issues are rare thanks to EGOHOME’s high-quality foam and U.S.-based production.

Why EGOHOME Mattresses Stand Out

When it comes to expansion time and performance, EGOHOME mattresses are crafted for excellence:

• CertiPUR-US® certified memory foam

• Fiberglass-free, safe for families and sensitive sleepers

• Designed for adjustable and platform bed frames

• Cooling gel foam layers to promote airflow

Whether you choose the 12" or 14" option, EGOHOME delivers premium comfort with reliable structure.

Real User Reviews on Expansion

“I was surprised—it looked flat at first, but within 2 hours it was 90% expanded. By the next morning, it felt amazing!”
“Unboxed it in the afternoon and slept like a baby that night. Perfect support.”

Tips to Speed Up the Expansion

• Unbox the mattress immediately after delivery

• Let it rest on a firm, flat surface

• Keep the room temperature above 20°C (68°F)

• Avoid adding bedding or sleeping until initial shape forms

• Allow at least 24 hours before judging final feel
