Should You Remove the Plastic Cover from a New Mattress?

Furniture Experts Share an Important Reminder Many People Miss**

When buying a new mattress, many people choose to leave the plastic cover on, believing it will keep the mattress clean, dust-free, and protected from moisture. However, according to furniture experts, this seemingly careful habit can actually shorten the mattress’s lifespan and negatively affect sleep quality.

A furniture store owner recently shared a reminder that surprised many customers: the plastic wrapping is only meant for transportation and storage, not for sleeping on. Once the mattress arrives in your home, the plastic layer should be removed promptly.

Why leaving the plastic on is a mistake

1. Poor ventilation and heat buildup
Plastic does not allow air to circulate. When you sleep, body heat and sweat become trapped, creating a warm, humid environment inside the mattress. Over time, this can lead to discomfort, night sweats, and restless sleep.

2. Increased risk of mold and bacteria
Moisture trapped by plastic creates ideal conditions for mold, mildew, and bacteria to grow. This is especially risky in humid climates and can trigger allergies, asthma, or skin irritation.

3. Faster mattress deterioration
Foam, latex, and spring systems are designed to “breathe.” Trapped moisture can damage internal materials, causing sagging, unpleasant odors, and a shorter overall lifespan.

4. Reduced sleep comfort
Sleeping on a plastic-covered mattress often feels noisy, sticky, and hot. This can interfere with deep sleep and affect overall sleep quality.

What is the right way to protect a mattress?

Instead of keeping the plastic on, experts recommend using a breathable mattress protector made of fabric. These protectors shield the mattress from spills, dust, and stains while still allowing proper airflow.

The takeaway

The plastic cover protects your mattress before delivery, not after. Removing it early helps maintain hygiene, improves comfort, and preserves the mattress for years to come.

As the furniture store owner put it:
“Plastic looks like protection, but in reality, it slowly damages the mattress from the inside.”

Sometimes, a small change in habit can make a big difference — and many people only realize it after years of uncomfortable sleep.
