Does Lull Mattress Smell? Odor, Off‑Gassing, and What to Expect

If you’re asking “Does Lull mattress smell?”, you’re usually trying to find out whether there’s any noticeable odor when you first unbox it, how long it might last, and if it’s something to worry about. This guide walks through what that smell is, how common it is with foam mattresses in general, and simple steps to reduce it.

Does Lull Mattress Smell When You First Open It?

Many people notice a light to moderate “new mattress smell” when they first unbox a foam mattress. This is often called off‑gassing.

Off‑gassing is the release of trapped odors from:

  • Fresh foams
  • Adhesives
  • Packaging materials

When people ask “Does Lull mattress smell?”, they are usually describing:

  • A slight chemical or plastic-like scent, or
  • A “new product” smell, similar to a new car or new furniture

For most sleepers, this smell:

  • Is strongest in the first few hours
  • Tends to fade significantly over the first few days
  • Often becomes barely noticeable after the mattress has fully aired out

Why Does a New Mattress Smell at All?

What Causes the Initial Odor?

Foam mattresses are manufactured, compressed, and sealed in plastic. While they’re wrapped, some of the natural odors from new materials build up inside the packaging. When you open the box, those trapped scents are released at once.

Common sources of odor include:

  • Foam layers made from synthetic materials
  • Glues or adhesives used to bond layers
  • Plastic wrapping and shipping materials

This is why many new foam mattresses share similar off‑gassing characteristics, even if they’re made by different companies.

Is the Smell Permanent?

The new-mattress smell is generally temporary. Over time:

  • Air circulation helps dissipate odors
  • The foam layers settle and stabilize
  • Most people notice the smell disappears or becomes very faint

If you’re especially sensitive to odors, it may feel stronger or more noticeable, but it still tends to improve with ventilation and time.

How Long Does the Smell Usually Last?

There is no single exact timeline that applies to everyone, but in typical experiences with new foam mattresses:

  • First 24 hours: Smell is often most noticeable
  • Days 2–4: Many sleepers report a clear reduction in odor
  • After the first week: Most people find the scent minimal or gone

When wondering “Does Lull mattress smell for a long time?”, it may help to remember that:

  • The height of the foam layers
  • Room size and ventilation
  • Temperature and humidity all play a role in how quickly odors fade.

A well‑ventilated, warm, and dry room tends to reduce odors faster than a small, closed, or humid space.

Does the Smell Mean the Mattress Is Unsafe?

Understanding Odor vs. Safety

A noticeable smell does not automatically mean a product is unsafe. Many everyday items have a scent when new, including furniture, cars, carpets, and shoes.

However:

  • Some people are more sensitive to smells in general
  • Others may experience temporary irritation or discomfort from any strong odor

If you’re very sensitive:

  • Consider airing out the mattress in a separate room before sleeping on it
  • Give it a few days of ventilation with windows open, if possible

If you have any concerns about how odors affect your personal health, it’s best to talk with a qualified professional for individualized guidance.

How Can I Reduce or Avoid the New Mattress Smell?

When people search “Does Lull mattress smell and how do I get rid of it?”, they’re usually looking for practical solutions. These common steps can help minimize and shorten the off‑gassing period:

  • Unbox it quickly
    Don’t leave the mattress compressed in the box for longer than necessary. Once it’s in your home, open it so it can start airing out.

  • Ventilate the room
    Open windows and doors if you can. Air movement helps Odors disperse more quickly.

  • Use a fan
    A simple fan aimed across the mattress surface helps speed up airflow and odor release.

  • Wait before adding bedding
    Let the mattress breathe for a few hours before putting on sheets, a protector, or a topper.

  • Consider a mattress protector
    After airing, a breathable protector can create a light barrier between you and any remaining scent.

For most households, a combination of fresh air, time, and patience is enough to bring the smell down to a comfortable level.

What If I Can Still Smell It After a Few Days?

Odor sensitivity varies widely. If you’re still noticing a smell and wondering again, “Does Lull mattress smell this way for everyone?”, the answer is usually no—people perceive scents differently.

You might:

  • Air the mattress in a different, more ventilated room
  • Increase airflow with additional fans
  • Give it a few more days, especially if the room is small or closed

If the smell continues to bother you over time, it can be helpful to contact the seller’s customer support for mattress‑specific guidance.
