What you need

Around 1/2 yard (0.90m) of fabric for most 18-inch doll beds. Cotton fabric is the easiest to sew. I used quilting cotton.
Polyester or foam stuffing. If you don’t have stuffing, substitute fabric scraps. Using fabric scraps makes the mattress a little heavier but is a cheap alternative. Cut the scraps up into small pieces to minimize lumpiness.

Step 1: Measure the Bed

First, measure the base of your bed. This bed was purchased from IKEA and measures 12 by 19 inches (30.5×48.2cm) at the wooden base.

Tip: Make sure you are measuring just the base and not the sides of the bed. You want the mattress to fit snuggly inside the bed frame.

Step 2: Cut the Fabric

Cut 2 pieces of fabric the size of the base plus 1-inch (2.5cm) seam allowance all the way around.

So cut 14 x 21 inches (35.5cmx53.3cm) (Remember my base was 12×19″)

Step 3: How to Make a Doll Mattress – Stitch the Sides

With RIGHT sides together, stitch around the mattress pieces with a 1/4 inch (6mm) seam allowance leaving a 3-inch gap (7.5cm) at one of the short ends.

It always looks neatest if you leave your gap at the end of the bed.

Step 4: Box the Corners

Box the corners by finger pressing open the seams at the corners and then aligning the top and bottom of the seam. Mark across where it is 1 1/2 inches (4cm).

The purpose of boxing the corners is to give some height to the mattress.

Stitch across the boxed corners and trim them straight across.

Step 5: Stuff the Doll Mattress

Turn your mattress the right way out and start stuffing.

If you are using polyester fill it is best to break it into small tufts. You want your mattress to look flat and not overstuffed so go slowly. Make sure you have stuffing in the corners to give it a good shape.

Before you close the gap, try it on your bed to make sure it is sitting flat like a mattress.

Take time to stuff the mattress carefully. Dolly would not like a lumpy bed to lie on and no fairy tale princess would ever be able to sleep on your doll’s bed!

Step 6: Close the Gap

Hand stitch the gap closed with a ladder stitch for an invisible closure.
