How To Put On Mattress Encasement: Step‑by‑Step Guide and Common Questions

If you’re searching for “How To Put On Mattress Encasement,” you’re likely trying to protect your mattress from spills, dust, or pests and want to avoid wrestling with a bulky cover. This FAQ-style guide explains what a mattress encasement is, how to put it on correctly, and how to avoid the most common mistakes.

What Is a Mattress Encasement?

A mattress encasement is a fabric cover that completely surrounds your mattress on all sides, usually with a zipper closure. It’s different from a simple fitted sheet or mattress protector, which only covers the top and sides.

Encasements are often used to:

Help keep dust, dirt, and debris off the mattress
Provide a barrier against spills or stains (depending on the material)
Create a full wrap around the mattress for added protection

Using one correctly can help keep your mattress cleaner over time and reduce the need for deep cleaning.

How To Put On Mattress Encasement: Step‑by‑Step

The easiest way to understand how to put on mattress encasement is to break it into clear steps. You may find it helpful to have a second person if the mattress is heavy or large.

1. Prepare the Mattress and Room

Before you begin:

Strip the bed: Remove all sheets, blankets, and toppers.
Check the mattress: Make sure it’s dry and free from visible debris.
Clear space: Give yourself room to move around all sides of the bed.

If your mattress is on a heavy frame, you might not need to move it, but having open access at least on three sides usually makes the process easier.

2. Unpack and Identify the Opening

Take the encasement out of its packaging and unfold it:

Find the zipper opening and note which end is the head or foot (if labeled).
Make sure the zipper is fully open so the encasement is like a large fabric “bag.”

Avoid dragging the encasement on rough floors to prevent snags.

3. Position the Encasement on the Mattress

There are two common methods.

Method A: Standing Mattress (often easier for two people)

Gently tilt the mattress on its side and lean it against a wall or sturdy support.
Slide the open encasement over the top of the standing mattress like a sleeve.
Pull it down evenly until the encasement reaches the bottom edge.

This method can make it easier to keep the encasement straight and avoid bunching.

Method B: Mattress Flat on the Bed

Lay the encasement flat on the bed with the opening at the foot.
Lift one corner of the mattress slightly and tuck that corner of the encasement underneath.
Repeat with all corners, gradually working the encasement around and under the mattress.
Gently pull the encasement up and over the mattress until it fully covers the top side.

Move slowly to keep the fabric from stretching or tearing.

4. Smooth and Adjust Before Zipping

Once the mattress is fully inside:

Check corners: Make sure each corner of the mattress is seated in the corner of the encasement.
Smooth wrinkles: Run your hands along the sides and top to flatten large folds.
Align the zipper so it closes easily without pulling too tightly across any section.

This step helps the encasement look neater and reduces tension on the zipper.

5. Zip the Encasement Carefully

Starting at one corner:

Gently zip around the mattress, guiding the zipper track with one hand.
Avoid forcing the zipper over thick seams or folds.
If the encasement has a zipper cover or fabric flap, secure it once closed.

A smooth, fully closed zipper is important for complete coverage.

Common Questions About Putting on a Mattress Encasement

Do I Need Help, or Can I Do It Alone?

You can often put on a mattress encasement by yourself for smaller or lighter mattresses. For larger or heavier mattresses, another person can make lifting and positioning much easier and reduce strain.

Should I Wash the Encasement Before Using It?

Many people prefer to wash textile products before first use. If the care label allows machine washing, you can wash and fully dry the encasement before putting it on. Always follow the care instructions to avoid shrinking or damaging the fabric.

Can I Use a Mattress Topper or Pad Over the Encasement?

Yes. The usual order from bottom to top is:

Mattress
Mattress encasement
Optional mattress protector or pad
Mattress topper (if used)
Fitted sheet and bedding

This way, the encasement stays in place, and you can wash the outer layers more often.

What If the Encasement Seems Too Tight?

A snug fit is normal, but you shouldn’t have to force the zipper:

Double‑check the size (twin, full, queen, king, etc.).
Make sure the mattress is not larger or thicker than the encasement’s listed dimensions.
Smooth out any bunching that might be stealing extra space.

If it still feels extremely tight, it may be a size mismatch.

How Do I Care for the Encasement Once It’s On?

To maintain your encasement:

Follow the care label for washing frequency and water temperature.
Avoid harsh bleach or very high heat if not recommended.
When removing it for washing, unzip fully and peel it back gently instead of yanking.

Most people wash the encasement less often than sheets, since it sits under other bedding layers.
