The other day I shared with you the plan for the Full-Size Farmhouse Pallet Bed for my son’s room.  One of the things that was very important to my son was that there be room for his buddies to spend the night. My extroverted son would have a friend spend the night every day of his life if we would let him.

So it was time to build a Rolling Trundle Bed!

By raising the side panel of the bed to 16” from the floor there was more than enough clearance for the rolling trundle bed with a mattress to slide underneath.  And the trundle only costs $38 in lumber.

That is a steal compared to what even a metal trundle retails for.  And it is a super easy build.

Here is the supply and cut list for both the Farmhouse Pallet Bed and the Rolling trundle.

TIP: Keep in mind that both a twin and a full-size mattress are 75” long.  So you are kind of shoving your mattress in to fit this trundle.  

Please measure your bed first before attempting this.  And read the comments below.

The trundle ends up being 73” long to fit the mattress in so it is a tight fit.  If your mattress doesn’t have much give you will have to make adjustments to both the trundle and the side pieces of the farmhouse pallet bed so you have adequate room to roll it under. 

I made sure to have 1” space left to right to roll the trundle in.

Also if your bed is wider than 35″ make sure to make adjustments to that dimension as well.

How to Make the Rolling Trundle

Step 1

Drill two pocketholes into each end of the 34” 2 x 6 pieces.  Attach that to the long 76” pieces.

Step 2

Next cut 6 – 2 x 4s to 34”.

Add two pocketholes to each end of those.

Then attach those to the frame with the 3 1/2” side facing up.  Make sure you add the braces all the way to the head and foot of the trundle.  This is what you will be attaching your wheels to.

Step 3

Flip it over and add your 1 5/8” rolling casters to the bottom with 1 1/4” screws.

Step 4

Make sure it is square. Then rip a piece of OSB to fit inside (33 7/8” x 72 7/8”) and screw that down with 1 1/4” screws.

I like to sand all of my pieces prior to assembly so it is ready for stain right away.

Always use a pre-wood conditioner on pine wood.  I used Minwax Special Walnut on mine.

  1. Love the bed!!! Might you be willing to share where you purchased his sheets and comforters? I’m looking for something like that for my son’s room!! Thanks!!

  2. Thank you so much, Jennifer! The bedding is actually an experiment. I found this zip it bedding from Bed Bath and Beyond. It zips on both sides, and I was hoping it would help my son be able to make his bed easier because all he has to do with zip it. The jury is still out on whether or not it’s going to work. 🙂

  3. On the trundle, what size pocket hole screws did you use on the 2×4 and 2×6? Did you use the Kreg regular jig or the HD jig? Thank you. Great pictures….can you also show how you fastened the wheels on the bottom?

  4. I’m a little challenged when it comes to measurements, and, I’m not seeing how the OSB platform measures 34-7/8″ x 72-7/8″ to fit inside the trundle frame.

    Wouldn’t it measure 34″ x 70″?

  5. Actually on my cut list it measures 33 7/8” by 72 7/8”. You are correct in thinking that the space is 34 x 73,” but I leave a little wiggle room to set the board into place. I hope that helps!

  6. How wide is your twin sized mattress? We made this trundle per your specs (admittedly, we should have measured our mattress first) and it is way too narrow. Both of our twin-sized mattresses are 37″ wide 🙁 No matter how we tried, we couldn’t cram it in there. Love the idea, though! We are going to use the trundle that we made for something else (not sure yet) and make another that should fit our mattress.

  7. Its great, still amazed how can its possible on as much cheap price. If buy in market one trundle bed will cost around 300 usd minimum.

  8. We too made this bed and found the measurements to not work for either a standard twin or a trundle twin. Wish we would’ve read the comments before making, since we now have to remake it and buy all new lumber.

  9. I want to make this for the toddler mattress I kept I’m wondering about the thickness of the OSB. I’m a laymen but what thickness is needed to carry the weight of mattress + preschooler weight (about 40 lbs)?

  10. Apparently, a standard twin is 38″ wide. Our fault for not double checking that as well. We made ours according to the cut list provided and it dis not fit. I think most people would assume there aren’t differences in sizes so you would have probably made the same assumption we all did. Are you maybe able to edit the post to give people that forewarning? We appreciate the information and the bed looks great!
