How Long Do Nectar Mattresses Take To Expand? A Clear FAQ Guide

If you’ve just unboxed a new foam mattress and are wondering “How Long Do Nectar Mattresses Take To Expand”, you’re not alone. Many sleepers want to know when it’s safe to sleep on the bed, how long it needs to “inflate,” and what’s normal during the expansion process.

This FAQ-style guide walks through what to expect, why expansion time matters, and how to tell if your mattress has fully taken shape.

What Does “Expansion Time” Actually Mean?

When a mattress arrives compressed and rolled in a box, it needs time to regain its full size and shape after unboxing. This process is called expansion.

For foam mattresses, expansion involves:

  • The foam re-inflating with air
  • Layers settling into their intended thickness
  • The cover smoothing out and relaxing

Understanding How Long Do Nectar Mattresses Take To Expand helps you plan when to unbox, set up your bed frame, and start using your new mattress comfortably.

How Long Do Nectar Mattresses Take To Expand on Average?

Many boxed foam mattresses begin expanding as soon as you remove the plastic. In typical conditions:

  • They often reach a usable shape within a few hours
  • They may continue to firm up and fully expand over 24–72 hours

So when people ask “How Long Do Nectar Mattresses Take To Expand”, the practical answer is usually:

  • You can often lie on it the same day, once it looks evenly expanded
  • Full expansion and feel may take up to a few days

This time frame can vary slightly depending on room conditions and how long the mattress was compressed before delivery.

Can You Sleep on the Mattress Before It Fully Expands?

Many sleepers choose to sleep on their mattress the first night, as long as it appears:

  • Flat and level
  • Close to its normal height
  • Comfortable and supportive enough for them

A few points to keep in mind:

  • Lying on the mattress during the first day or two can sometimes help the foam loosen and expand more evenly.
  • If parts of the mattress still look noticeably compressed or lumpy, it can be helpful to give it more time before using it as your primary sleep surface.

When considering How Long Do Nectar Mattresses Take To Expand, it’s useful to think of comfort and appearance as your main guides rather than exact clock time.

What Affects How Fast the Mattress Expands?

Several everyday factors can change how quickly a foam mattress reaches its full size:

1. Room temperature
Foam typically responds faster in a warm room and more slowly in cooler temperatures. A very cold bedroom can make the foam feel firmer and slow expansion.

2. Humidity and airflow
Moderate humidity and some airflow can help the mattress decompress more smoothly. A very damp, closed-off room may slow things down.

3. Time in the box
If a mattress has been compressed for a longer time before delivery, it may take a bit longer to fully expand once opened.

4. Mattress size and thickness
Thicker models and larger sizes generally have more foam layers to expand, which can slightly extend the time until they feel fully settled.

How Do You Know If It Has Fully Expanded?

Instead of focusing only on How Long Do Nectar Mattresses Take To Expand, it helps to look at visual and feel-based signs that it’s ready:

  • The mattress height is close to the listed thickness
  • The surface looks even, with no deep dips or corners that appear crushed
  • The cover is smooth and taut, not wrinkled or bunched
  • It feels consistent and supportive from edge to center

If you notice persistent low spots or sagging areas after a few days in normal room conditions, that may be a sign to monitor more closely.

Is It Normal for One Side to Expand Faster Than the Other?

Yes. It’s common for:

  • Corners to take a little longer to rise
  • One side to look slightly lower for the first several hours

You can gently help the process by:

  • Lightly pressing or smoothing the cover toward stubborn corners
  • Ensuring the mattress is on a flat, supportive surface (not slats that are too far apart)
  • Letting it breathe by keeping sheets and protectors off for the first few hours

These minor differences usually fade as the mattress settles over the first day or two.

What About New Mattress Smell During Expansion?

Many new foam mattresses release a temporary “new product” odor as they expand. This is often more noticeable in the first 24–48 hours.

To help:

  • Open windows or doors to increase ventilation
  • Let the mattress air out uncovered before adding bedding
  • Use light bedding at first instead of heavy comforters that trap air

The slight smell typically diminishes with time as the mattress finishes expanding.
