If you’re wondering “Can You Sleep On a Leesa Mattress The First Night?”, you’re likely about to unbox a new mattress and want to know if it’s ready for immediate use.

Can You Sleep On a Leesa Mattress The First Night?

In most everyday situations, yes, you can sleep on a Leesa mattress the first night after unboxing.

These mattresses are usually compressed, rolled, and boxed. Once opened, they start expanding right away. Many sleepers lie on them the same day they arrive and use them like a regular mattress.

However, it can be helpful to understand a few common first-night details before you do.

How Long Does It Take to Fully Expand?

Is it safe to use before it’s fully expanded?

After unboxing, a new foam or hybrid mattress usually reaches a usable shape within minutes to a few hours. It may continue to firm up and expand over the next day or so, but:

It typically looks like a regular mattress within a short time.
You can usually lie and sleep on it the same day without harming the mattress.

Some people feel the mattress get slightly more supportive over the next 24–72 hours as it completes expansion.

Will sleeping on it too soon damage it?

In ordinary home conditions, sleeping on the mattress the first night does not usually cause damage. These products are designed to be used in real-life settings, where people are eager to sleep on them right away.

If you’re concerned about performance, you can:

Give it a few hours to rise before making the bed.
Check that the corners and edges have mostly expanded.

What About the New Mattress Smell?

Is off-gassing normal?

When considering “Can You Sleep On a Leesa Mattress The First Night”, many people are really asking about the new mattress smell, sometimes called off-gassing.

Common points to know:

A noticeable but temporary odor after unboxing is common with foam-based mattresses.
The smell usually fades over time, especially with good airflow.
Opening windows or using a fan can help the scent dissipate more quickly.

Is it okay to sleep on it while it airs out?

Many people choose to sleep on the mattress while it’s still airing out, especially if the smell doesn’t bother them. Others prefer to:

Open the mattress in the morning.
Let it air out for several hours.
Put on bedding and use it later that day or night.

If you are particularly sensitive to smells, you may want to allow extra airing time before your first full night on the mattress.

Will It Feel “Right” the First Night?

Does the comfort level change over time?

Even though you can sleep on a Leesa mattress the first night, it may not feel exactly the same on day one as it does after a few weeks.

Common experiences include:

The mattress softening slightly as materials relax.
Your body adjusting to a new level of support, especially if your old mattress was worn out.
Some sleepers noticing minor body aches or stiffness during an adjustment period.

This is normal when switching to a different type of mattress, such as going from a very old or sagging bed to a more supportive foam or hybrid design.

How long is the adjustment period?

Many sleepers feel they fully adapt over several nights to a few weeks. During that time:

Try to sleep in your usual positions.
Give your body a chance to get used to the new surface.
Avoid judging comfort based on only one or two nights.
