How To Make a Mattress Cover: Step‑by‑Step FAQ Guide

If you’re searching for “How To Make a Mattress Cover,” you’re likely looking for a simple, clear way to protect your mattress using materials you choose yourself. This FAQ walks through what a DIY mattress cover is, how to make one, and what to consider before you start cutting fabric.

What is a DIY mattress cover?

A DIY mattress cover is a removable fabric layer you sew (or assemble) to fit snugly around your mattress. It can:

Help protect against everyday wear and surface dirt
Make an older mattress feel cleaner and fresher
Let you choose fabric type, thickness, and style

Unlike a fitted sheet, a mattress cover usually fully encases the mattress or at least wraps around the top and sides with a secure closure.

Why would I make my own mattress cover?

People look up How To Make a Mattress Cover for a few common reasons:

Customization: Choose fabrics that feel good against your skin or match your bedroom.
Fit: Create a cover that fits a non-standard mattress size, such as custom or extra-thick models.
Cost control: Use materials you already have, like sturdy sheets or fabric remnants.
Care: Make a design that’s easy to remove and wash regularly.

A DIY cover is mainly about surface protection and comfort, not about changing the internal structure of the mattress.

What materials do I need to make a mattress cover?

The exact list depends on your design, but most basic covers need:

Fabric: Cotton, cotton blends, or other woven fabrics are common.
Measuring tape
Fabric scissors
Sewing machine (or hand-sewing needle and strong thread)
Zipper, buttons, ties, or elastic for closure
Pins or clips

Many people choose medium-weight woven fabric that is durable but still soft and breathable. If you want extra cushioning, you can layer a thin quilted fabric on top.

How To Make a Mattress Cover: What are the basic steps?

Here is a straightforward method for a zippered encasement-style cover that wraps the top, bottom, and sides of your mattress.

1. Measure your mattress carefully

Measure:

Length (head to toe)
Width (side to side)
Depth/height (top to bottom)

Write these down, then add seam allowances, usually 1–2 cm (about ½ inch) to each edge you will sew.

2. Plan your fabric pieces

You’ll need:

Top panel: mattress length × mattress width
Bottom panel: mattress length × mattress width
Side panels: strips that match the mattress depth and wrap around all four sides

You can either:

Cut four separate side strips (one for each side), or
Cut one long strip that wraps around all sides (length = 2 × length + 2 × width).

Remember to add seam allowances to all edges.

3. Cut the fabric

Lay the fabric flat on a clean surface. Use your measurements to:

Mark the top, bottom, and side pieces
Check measurements twice before cutting
Cut smoothly with sharp fabric scissors to avoid fraying and uneven edges

4. Sew the side panels into a “wall”

Join the side pieces (right sides together) along their short edges
Sew to create a continuous band that matches the perimeter of your mattress
Press seams flat if possible; this can help the cover sit more smoothly

5. Attach the top panel

Place the top panel and side band right sides together
Align corners and pin around the perimeter
Sew around all four sides, keeping seam allowances consistent

You should now have a “lid” that looks like a fitted box without a bottom.

6. Add the zipper or closure

There are several ways to close the cover:

Full-length zipper along one long side and partly along two short sides
L-shaped zipper along one long side and one short side
Buttons, snaps, or ties along one side (simpler, but usually less snug)

Attach the zipper or closure to the edge of the side band and the bottom panel according to normal sewing practices, keeping right sides together while sewing.

7. Attach the bottom panel

With the zipper partly open, pin the bottom panel to the side band (right sides together)
Sew most of the way around, leaving the zipper or closure area open as planned
Turn the entire cover right side out through the open zipper or closure

Now you have a complete encasement-style DIY mattress cover ready to slide over your mattress.

Can I make a simpler mattress cover without a zipper?

Yes. If you want a very basic approach, you can make a fitted-sheet style cover:

Cut a top panel using your mattress length and width.
Add a wide border (to match depth) plus extra fabric to tuck under.
Sew elastic around the edges so it grips under the mattress, similar to a fitted sheet.

This design is generally easier to sew but usually protects only the top and sides, not the bottom.

What fabric should I choose for a homemade mattress cover?

When considering How To Make a Mattress Cover, fabric choice matters for comfort and ease of care:

For breathability: Light to medium cotton or cotton blends
For durability: Tightly woven fabrics with a bit more weight
For easy washing: Fabrics that can go through regular machine washing and drying

If you’re unsure, many people start with plain woven cotton because it is widely available, familiar to sew, and comfortable for most sleepers.

How do I care for a DIY mattress cover?

To keep your handmade cover in good shape:

Wash it on a gentle cycle the first time to see how it behaves.
Use mild detergent.
Dry according to the fabric’s general care guidelines (air-dry or low heat is often safest).
Re-check seams, zippers, and elastic occasionally and repair loose stitches early.

Regular washing helps keep your sleep surface feeling fresh and tidy.
