DIY Co-Sleeper Plans

Well, I’m finally getting around to posting the plans for my DIY Co-Sleeper.  I hope you find them helpful :)  See the step by step process complete with photos here.

DIY Co-Sleeper @ Ordinary Happily Ever After

Shopping List

  • ½ sheet ¾ inch plywood
  • 1- 2 x 4 – length will depend on the height of your bed (5 feet long should be plenty unless you have an unusually tall bed) **you could use the left over plywood to fashion some 2 x 4’s if you wanted to save on the expense.**

Tools

Cut List

  • Body
    • 1 – ¾ inch plywood @ 15” x 36”
    • 2 – ¾ inch plywood @ 15” x 12” (round off one corner of each piece with jigsaw and sander)
    • 1 – ¾ inch plywood @ 12” x 34 ½”
    • Co-Sleeper Legs
      • 2 – 2X4 @ * (measure the distance from the bottom of co-sleeper to the floor when fitted to your bed)
      • Under Mattress Support
        • 2 – ¾ inch plywood @ 4” x 3’

Instructions

  •  Step 1 – Build the box
    • Use your Kreg Jig to drill pocket holes in the side pieces

    • Attach sides to the base using 1 1/4 inch screws.

    • Drill pocket holes for the back

    • Attach the back to the bottom first, then to the sides (if you find the 1 ¼ inch screws too troublesome, try 1 inch screws)

  • Step 2 – Attach under-mattress sliders
    • Screw the sliders to the underside of the base (no pocket holes here.  Just screw them straight down into the wood).  You want the sliders to be pretty far underneath the box, but make sure you leave enough room for the legs.  I used four screws on each slider, two towards the back of the box, two towards the front.

  • Take your box to the bed you will be using it with.  Slide the sliders underneath the mattress (if you use a box spring side it between the mattress and box spring) and push it as tight up to the mattress as you can (your mattress will act as the fourth side of the crib).  Measure from the floor to the base of the box.  Then cut your boards.  You can see how I did it here:  My legs needed to be just over 16 1/2 inches.  I cut them at 16 1/2 and made up the difference with felt to protect the floor.

Step 4- Attach legs to the base.

  • Drill some countersink spaces and drive the screws into the legs from the top using 2 1/2 inch screws.

Voila!  Fill your holes, nooks and crannies, sand it down, paint, stain it upholster it or just plain make it pretty!  Add a foam mattress and it’s perfect for you to keep your little one close for those midnight feedings!

  1. wow, that’s a clever idea. I had all my babies in our bed — five. I used to have the crib up against the bed and the side removed. It’s cozy when you get two young-ones in there!

  2. Awesome!

  3. You mention 1/2 sheet of plywood for materials. What are the dimensions of a full sheet?

  4. Pregnant for my 5th as well, cant wait to make one of these

  5. Hi, love your co sleeper design! My husband and I r getting materials today to build one. Scheduled 3 weeks from today with dd #2. I have 2 questions. What r the pocket holes for? Is that for air ventilation? Second question is how deep of a pad did u get for it and is the pad level with your mattress or does it sit slightly lower than your mattress? Thank u and so glad u posted this diy! :)

    • Hey Nichole, thanks for commenting! The pocket holes are where I put the screws to join the pieces of wood together. I used a Kreg Jig to drill them and have found that it makes some really great joints. If you have more experience in carpentry I’m sure you could use more sophisticated joints, but for me the pocket holes are great. You can read this post for step by step instructions with pictures.

    • I used a four inch thick piece of foam and found that it was MORE than enough. I honestly think a two inch would have been perfect, but I was worried about him being comfortable (turns out a 10 pound baby doesn’t need much support). With the four inch foam, the sides of my co-sleeper are about six to eight inches above his mattress and only three inches above mine. So his mattress is a few inches below my mattress. Hope that helps :)

  • Hi!
    You’ve completely inspired me to make this for my first baby, due in February. I was wondering if you possibly knew the inner dimensions of the co sleeper? Thank you for posting this!(:

  • I would love to make one of these. My only concern is the type of bed we have: an Ikea bed frame (Malm style) with adjustable support slats and a memory foam mattress on top. About one inch of the mattress is nested inside of the frame, and by the very nature of the slats, there aren’t any flat surfaces (like you would have with a traditional mattress/boxspring). I’m afraid that the support slats for the co-sleeper will either damage the slats or be damaged by the weight of my body on top of them. Do you have any ideas around this?

    • It seems like that would be simple enough to customize. I would probably use a solid plywood board under the mattress since you already have slats that has an inch indentation customized for your bed. Either that or I would build a platform to put under the mattress to lift it up. Hope that helps!

  • Hi, my husband and I want to make a co-sleeper for our 3 month old who ends up in our bed every night. I’ve been looking for a foam mattress I can cut to size and I’m not finding much online that seems like it would work with the co-sleeper. Can you tell me what you used and where you bought it? Thanks!

    • Hey Emilee, I tried looking for where I bought our mattress but couldn’t find it anywhere. It was just a 4 inch piece of foam that we cut down to the right size. It think it was six by three or four feet. Four inches ended up being too much and I could have gotten away with half of that. I think I ended up paying around $60 shipped but I had enough left over to use as a mattress in our pack and play.

  • I was just gonna mention for people with mattresses going below the frame, a few L shaped metal joints might work. Their just a small metal L shaped solid metal that screws on both ends. Use it to simply hang on the bed frame. Use four to be safe.

  • As far as foam goes, those nap time pads that they use at day cares are easy enough to cut open and that’s all that’s in them. Those only cost like $5.
