Make your own doll mattress for American girl doll furniture and beds with this simple step by step sewing tutorial designed for beginners.

I'd be the first to tell you that sewing intimidates me.

Because a board does what I tell it too. And it stays straight when I cut it. Fabric, well, doesn't. At least not for me.

I've sewed doll mattresses before in the traditional "box cushion" style, which means cutting six different pieces of fabric, and then accurately sewing them together in a 3D box, with corners matching. It was never a fun or easy process.

But this time, Grace Grandma showed me something really neat. And 10 times faster. All you do is sew two squares of fabric together, and then you clip the corners with seams, and you've got a box cushion without all the fuss!

I could not believe how easy this doll mattress was to make for Grace's American girl doll. In this tute, I've included how to size for any size doll mattress (or even a dog bed or nap mat or floor cushion!) and you can skip the tufting to save steps.

Cut to size

Preparation

Shopping List

For one mattress finished size 10" x 19" I used:
1/2 - yard of fabric
Thread
Stuffing from recycled pillows and stuffed animals
Mix-matched buttons

Cut List

2 - Pieces of Fabric 2 1/2" wider and 2 1/2" longer than the desired finished mattress size (for 2" thick mattress)

General Instructions

Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!

Instructions

Step 1

Determining Size

Determine the desired length and width of your doll mattress. For Grace's American Girl, we decided to make the mattress overall 10" x 19" finished dimensions. This also fits the doll bunk bed (shown in photos and plans available here).
Then add 2 1/2" to each of these dimensions. For Grace's American Girl bed, the dimensions are 12 1/2" x 21 1/2". Cut two pieces of fabric to the determined measurements.

Sewing the Edges

Sandwich the two piece of fabric right sides together and pin. Baste with 1/4" inseams around all sides, leaving a 3" opening for inside/out-siding the doll mattress.

Step 2

Clip Stitching Corners

Now this a little tricky, but once you "get" it you'll breeze through. Open up the corners so the seams you stitched in step 1 are matched up, and the corner forms a 90 degree angle, with the seam down the center. Pin. Then line a ruler up with this seam and mark a 2" clip off the corner. Sew a seam right on the mark you made.

Grandma did the sewing on this one.  We are giving these mattresses away as a gift, and her sewing is so much better than mine.

Step 3

Seam Check

If done correctly the seam will look like the above diagram, and you can see the mattress taking on a box cushion like shape.

Step 4

Finished Corners

Once you have clipped seamed all four corners, inside outside the mattress and check your corners.  They should look like this corner.

Filling

You can fill the mattress with 2" thick foam, bean bag filler, or in our case, recycled pillow and stuffed animal stuffing. If you use pillow stuffing, fluff and fill but don't overfill.  Hand stitch opening closed.

Step 5

Step 6

Layout Buttons

Next, lay the buttons out in a desired pattern. Note that you will need twice as many buttons, for the top and bottom. Once you are happy, mark the location of the buttons on front and back.

Step 7

Pin Mattress

You will want to pin the mattress in multiple locations just to keep the mattress tops and bottoms from "moving" as you sew buttons on and ending up crooked.

Step 8

Sew Buttons

Then just start sewing the buttons on, one on top and one on the bottom.

Step 9

Admire Your Hard Work

Oh yeah, looking pretty!  Keep it up!

Step 10

Pillows and Blankets

With the remaining fabric scraps, Grace's Grandma made a blanket.  From her scraps from the 80's she found this quilted fabric and made a few pillows as well.  Just figure the finished dimensions, add 1/2" to length and width, cut and sandwich right sides together (step 1), inside outside and stuff.  

Step 11

No Buttons

And I wanted to show you that you don't have to have the buttons. You can make this mattress in just two simple step.
Finishing Instructions
Preparation Instructions
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

Oh yeah! Fake boxes. My favorite cushion technique.

If you are a perfectionist, you can sew a small tuck into the fabric from corner to corner to enhance the boxed look.

I combine that with an "envelope back" cushion cover, like used for pillow shams, where the back just overlaps. It makes nice couch cushion covers.

This project is more where my talent lies although I have high hopes of making the beds to put them on too. Last year I made all my girls in daycare baby doll diaper bags full of clothes, changing pads, etc. I love the idea of making them beds with mattresses and maybe blankets and rag dols to go with it. I'm very new to woodworking so we will have to see if I can figure it out well enough for gifts. I love your plans, so far on my first project very easy to follow. I can't wait to start on the baby doll stuff!

This is how I made my Grandaughters (x4) mattress for their doll beds, except I did NOT use buttons. In the place of buttons I used embroidery thread and make tucks. The reason I did this is because of their ages, 4 - 14 months. I am in the process of making the beds to go with the mattresses. Did it a bit backwards because of the heat in my state. Trying to plan ahead for Christmas gifts!!!

Thanks for all you do Ana!!!

At our daughter's request my husband made the bunkbed for our granddaughter for Christmas, so of course I got out my sewing machine and made the mattresses -- twice!

For the first 2 mattresses I used your dimensions: 12-1/2 x 21-1/2. Got the mattresses all stuffed and found them to be too short for the bed by about 2 inches! Well, I wanted the mattresses to fill the entire space, so I made another set using my dimensions: 12-1/2 x 24, and they fit perfectly.

I think what you forgot to figure was those nice boxy corners actually take up an extra 2-1/2 inches on each end of the mattress. Anyway, just thought I'd pass this along for anyone else making them.

The first set of mattresses won't go to waste, as I figure that our granddaughter's dolls will need a place to sleep when they come down with her to spend the night! It's all fun isn't it?! Thanks for the pattern!

Hey Loretta,
I know what happened because I almost did the same thing. At first I printed out the PDF format which does not show pictures. I realized my mattress was going to be the wrong size. I went back and looked at the pictures. On step 2, you place your ruler across the triangle and slide it down until the bottom of the triangle from side to side measures two inches - not from top down. When you do this, from top down only measures one inch. Does this make sense? Look at the picture and you see the two inches are across the bottom not up and down.

Lorretta.. I just started these this morning, same day as your post. I have them cut and everything, one even sewn completely... then I get on and see what you wrote! Now I am in a panic. My husband hasn't built the bunk bed yet.

Loretta.. will you do me a favor and measure your beds inside length. :-)

Oh ChelleWeezie, I didn't realize that you asked for these dimensions, so I'm really sorry to take so long to reply.

Inside dimensions of the bunk beds are 19" x 9.5"

I made my mattresses extra fluffy, so that may be why the first ones I made were too short. (I'm really surprised that no one else ran into this problem.)

You could just not stuff them quite so full and that would probably work. Or maybe add a nice big doll-size pillow, or even roll up the doll's blanket and place at the foot of the bed if you want to fill up the space. Your daughter will love the bunkbeds in any case!

My husband built the bunk beds last night for our oldest daughter for Christmas. Thankyou so much ! It was an answered prayer to find your sight ! Money is so tight this year and she was just dying to have an American girl Christmas. I was able to get the doll but when I looked at the accessories I almost cried in the middle of the store !!! But we found this site when looking to see if we could find someone who builds them and sales them. It was his first project EVER and he did awesome, I am quite fond of him but I think he may even have a talent for this. But the part that brings me to tears is this custom doll bed which was sturdy enough for my husband to sit on set us back a whopping 15 dollars ! Now for the scarrey part, I am going to have to try to sew for the first time ! lol Thank you so much and God Bless you ! You saved Christmas for my eight year old !

I just made the 'fancy' crib, bunk bed and mattress for all :) The girls couldn't decide on the fabric, so I used a pink fabric for one side and purple for the other! Super easy and quick!

if I was going to use an 1 1/2 '' thick matress instead of a 2 '"matress like the direction are shown - should I just subtract a 1/2 inch and only cut 2 pieces of fabric 2 inch wider and 2 inches longer than the desired finished matress instead of the 2 1/2 that is suggested for the 2" thick matress

This is so cute. My hubby just made it for our grandaughter. I will be making the mattress and pillows and then ship it to her. Hubby was so proud of himself after he finished it. We will be painting it to match her decor in her bedroom it is Disney colors. Thanks Anna

Hi -
I wanted to first Thank you for this tutorial. It was really helpful to me and my mom as we worked on making bedding for my daughters American Girl Doll beds. I also wanted to let you know that I am doing a post about our making of the bedding and mattress we just made. I will be linking to this post as it was the inspiration for how to make our mattress. Here is the link if you want to see the reference to your site. http://realcoake.blogspot.com/2012/10/american-girl-doll-bedding-patter…. Once again, thank you very much for your helpful tutorial. Have a great night.

I just finished making these mattresses for the bunk beds my husband is making. Thank you for such a simple method - I could not believe how quickly they were completed. I wanted to mention that I used coordinating bundles of 5 fat quarters (one bundle for the top bunk and one for the bottom) and used a different fabric for each side of the mattress so my daughter can flip it when she wants to. The fat quarters are 21", not the 21.5" required, so to compensate I just measured 1 3/4 inches for the clipped corners instead of 2 inches. They came out perfectly, and I used the other 3 fat quarters from each bundle to make both a double sided blanket and a pillow for each bed. It was an easy way to get a coordinated look!

My son is making the bunkbeds and I the bedding from my grand-daughter's birthday. If you want to make this even easier, go in your linen closet and find those pillow cases that you hate to toss even though they don't match anything else. The width of case was perfect for the length of the mattress, I just cut off the right size and had only one seam to sew.

Hi, Ana - Love the doll bed & bedding. I just made them for my granddaughter. The bedding took about two hours total for two beds. As a professional dressmaker of 30+ years, (and a woodworker for about 20), I wanted to suggest an amendment to the instructions for the mattresses. If you measure down from the corner 2", and mark a line across the corner, that line/seam will measure approximately 4", thus making a 4" thick mattress - not the 2" one that is mentioned in the tutorial. Measure down 1" for a 2"-thick mattress, which fits the little bed nicely. Also, I changed the cut size of the mattress, adding 2" for the 2" you're taking away in height, plus the 1/2" seam allowance, plus an extra 1/4" just for good measure. My dimensions were 12" x 21¾" for a 2" high mattress. For the original 4" high mattress, add 4" plus the doubled seam allowance. After filling all the nail & pocket holes, I sanded, then I spray painted the bed using Zinsser 123 spray primer, followed by Krylon all-surface spray paint. It looked gorgeous! Thanks for the darling bed and bedding. It was the hit of the birthday party with all the little girls!
