How Long Does a Nectar Mattress Take To Expand? A Clear FAQ Guide

If you’ve just unboxed a new bed-in-a-box, it’s natural to wonder: How Long Does a Nectar Mattress Take To Expand and when is it actually ready to sleep on? This guide walks through what to expect from expansion, why timing matters, and how to tell if your mattress has fully taken shape.

What Does It Mean for a Mattress To “Expand”?

When a mattress is shipped compressed and rolled, the foam layers are tightly vacuum-packed to fit in a box.

Expanding simply means:

  • The mattress regains its intended height and shape
  • The foams return to their normal density and feel
  • Any minor wrinkles or compressed areas smooth out

This process begins as soon as you remove the plastic wrapping and let air reach the mattress.

So, How Long Does a Nectar Mattress Take To Expand?

For people searching “How Long Does a Nectar Mattress Take To Expand”, the core answer is:

  • The mattress usually expands most of the way within a few hours
  • Many users notice it is sleepable the first night
  • Full expansion and fine-tuning of feel can take up to 24–72 hours

In other words, you can typically use the mattress relatively quickly, but peak performance and true contouring may not be fully noticeable until it has had at least a day or two to settle.

Why Does Expansion Time Matter?

Understanding How Long Does a Nectar Mattress Take To Expand helps you:

  • Plan your first night: Decide whether to sleep on it immediately or give it extra time.
  • Set realistic expectations: Newly opened foam may feel slightly different on day one than it will after a few days.
  • Avoid unnecessary concerns: A mattress that looks a little short or uneven at first is usually just finishing its expansion.

Common Questions About Expansion

Can I sleep on the mattress right away?

Many sleepers do choose to sleep on the mattress the same day they open it. The surface is usually supportive enough once it has had a couple of hours to rise.

However, leaving it to expand closer to the full 24–72 hours may allow:

  • A more consistent height from corner to corner
  • Foam layers to fully decompress
  • A more accurate feel compared to long-term use

What if the corners look a bit squished?

Slightly rounded or compressed corners and edges are common at first. These areas often:

  • Improve within the first 24 hours
  • Continue to even out over the next 1–3 days

If the rest of the mattress looks normal and the corners are gradually improving, this is generally part of normal expansion.

Is it bad if I use it before it fully expands?

Using the mattress during expansion is usually acceptable, as long as:

  • It has had some time to rise after unboxing
  • You’re comfortable with the feel in its current state

Sleeping on it early may slow expansion slightly in the areas where you lie, but the mattress typically continues to expand over time when it’s not in use.

Factors That Affect How Long Expansion Takes

Several conditions can influence How Long Does a Nectar Mattress Take To Expand:

  • Room temperature:
    Warmer rooms often help foam expand more quickly. Cold environments can make foam feel firmer and slower to rise.
  • Ventilation:
    A well-ventilated room can support a more even expansion and help any initial packaging odors disperse.
  • Foundation type:
    A flat, supportive base helps the mattress expand evenly. Very widely spaced slats or uneven surfaces may lead to minor dips until the mattress settles.
  • Time in the box:
    Mattresses that remain compressed for a long time before opening may need the full 24–72 hours to completely come back to shape.

How Do I Know If My Mattress Is Fully Expanded?

Look for these simple signs:

  • Height is close to the stated profile (within a small margin)
  • Surface looks smooth, with no large dips or ridges
  • Corners and edges appear fuller than they did immediately after opening
  • The feel has stabilized and no longer changes from one day to the next

If these conditions are met after a day or two, your mattress is likely expanded as intended.

Simple Tips to Help Expansion

A few easy steps can support a smoother expansion process:

  • Place the mattress in a room-temperature or slightly warm environment
  • Use a flat, supportive base
  • Give it airflow by removing bedding while it’s still expanding
  • Avoid heavy pressure on one small area during the first several hours
