How To Put a Mattress Cover On a Bed: Step‑by‑Step FAQ Guide

If you’re wondering how to put a mattress cover on a bed without it bunching, sliding, or feeling too tight, you’re in the right place. This guide walks through the process step by step and answers the most common questions about using a mattress cover correctly.

What Is a Mattress Cover, and Why Does It Matter?

A mattress cover (often called a protector or encasement) is a removable layer that goes over your mattress to help shield it from spills, dust, and everyday wear. Some covers fit like a fitted sheet, while others completely encase the mattress with a zipper.

Using one correctly can help:

• Keep your mattress cleaner over time
• Reduce direct contact between your body and the mattress surface
• Make it easier to wash just the cover instead of cleaning the whole mattress

Putting it on the bed the right way helps it stay smooth, comfortable, and effective.

How To Put a Mattress Cover On a Bed: Basic Step‑by‑Step

1. Prepare the Bed

1. Strip the bed
   Remove all bedding: pillows, sheets, blankets, and any existing mattress protector.

2. Check mattress size and depth
   Confirm that the cover matches your mattress size (twin, full, queen, etc.) and thickness.

   • If your mattress is extra thick, look for deep-pocket or “high-profile” sizing on the tag.

3. Position the mattress if needed
   If your mattress is heavy, it may help to move it slightly away from the wall so you can walk around it.

2. Identify the Corners and Orientation

Before you start, find the label or tag on the mattress cover. This often indicates:

• The head or foot of the bed
• The top surface (especially for waterproof or quilted covers)

Lay the cover out and make sure:

• The longer side aligns with the length of the mattress
• Any special surface (quilted, waterproof) is facing up, toward where you will lie

3. How to Put a Fitted-Style Mattress Cover On

Fitted covers work much like a fitted sheet.

1. Start at one corner
   Place one corner of the cover over a mattress corner at the head of the bed.

2. Secure the diagonal corner
   Move to the diagonal opposite corner at the foot of the bed and pull the cover over that corner. This helps keep the cover centered.

3. Fit the remaining corners
   Pull the elastic edges down over the other two corners, smoothing the fabric as you go.

4. Tuck and smooth
   Run your hands along the edges and surface:

   • Tuck in any excess fabric under the mattress
   • Smooth out wrinkles to avoid bunching under your sheet

🛈 Tip: If the cover feels very tight, lift each mattress corner slightly as you pull the elastic down instead of forcing it straight across. This reduces strain on the fabric.

4. How to Put a Zippered or Encasement Mattress Cover On

Encasement covers fully surround the mattress, often with a zipper.

1. Open the cover fully
   Unzip the cover completely so it lays flat or nearly flat.

2. Stand the mattress up (if possible)
   For large or heavy mattresses, it can be easier to:

   • Stand the mattress on its side
   • Slide the cover over like a large sleeve

3. Slide the cover on
   Gently pull the cover around the top and sides of the mattress. Take your time to avoid tearing seams.

4. Lay the mattress back down
   Once the cover is most of the way on, carefully lower the mattress back onto the bed frame or foundation.

5. Adjust and zip

   • Align the corners and edges
   • Fully close the zipper, making sure no fabric gets stuck
   • Smooth the surface with your hands

🛈 Tip: If you’re doing this alone, work in sections—pull the cover partway, adjust, then continue—rather than trying to pull it all the way on in one go.

Common Questions About Putting a Mattress Cover On

How tight should the mattress cover be?

A good fit is snug but not strained:

• The cover should stay in place when you sit or lie down.
• Seams and zippers should not look stretched or pulled.
• You should be able to slide a hand under the side without excessive effort.

If it’s extremely difficult to get the last corner on, the cover might be too small or too shallow for your mattress height.

Do I put sheets over the mattress cover?

Yes. Use your mattress cover first, then your fitted sheet on top. The typical order is:

1. Mattress
2. Mattress cover or encasement
3. Fitted sheet
4. Flat sheet (if you use one)
5. Blankets, comforter, or duvet

This keeps the cover protected and makes the bed more comfortable.

How often should I remove and wash a mattress cover?

Many people find it practical to wash their mattress cover when they wash their bedding regularly, or whenever there are spills or stains. Always check the care label for:

• Water temperature recommendations
• Whether it can go in the dryer or should be line-dried
• Any special instructions to protect waterproof layers or zippers

What if my mattress cover keeps slipping off?

If your mattress cover slides or pops off:

• Confirm the size matches your mattress.
• Make sure the elastic edges (for fitted types) are fully tucked under all corners.
• For very smooth mattress surfaces, placing the cover carefully and smoothing it out before adding your sheet can help it stay put.

Key points to remember about How To Put a Mattress Cover On a Bed

• Check size and depth first to ensure the mattress cover matches your mattress dimensions.
• Lay out and orient the cover so the long side and top surface are correctly aligned.

• For zippered encasements, open fully, slide on gently, then zip and smooth.
• Always place your fitted sheet over the mattress cover for comfort and protection.
