A trundle can add so much extra storage or even an additional sleeping space to a room. This trundle features a clever design that creates a solid bottom on the trundle.

General Instructions

The most important factor in building a trundle is ensuring it will fit under the bed. With this in mind, I am going to encourage you to build your trundle to the specifications of your bed. If you would like to use the trundle with a standard twin mattress, the overall clearnance length of your bed (the length between the legs on the sides) must be at least 77″. If you are building a bed, make note of this and build your bed so the side rails are 77″ long.

Instructions

Step 1

You must also understand the overall height of the trundle. Make sure your trundle will fit under the bed. The trundle I designed uses 1x8s, and you will need at least 8″ of clearnance under the bed. If you have more clearance, you can use a 1×10.
Measurents you will need:
A) Overall height or clearance under the bed
B) Overall distance between the legs of the bed (or the length of the siderails)
C) Width of the bed. Overall width of the bed is approximately 39″ for a twin.
Subtract 2″ from the overall height (A). This is approximately the greatest height you could make your trundle at. Of course you could make the trundle shorter.
Subtract 1/2″ from the overall measurement (B). This is the greatest possible length of the trundle. Of course, you can make the trundle smaller.
Remember, a standard trundle mattress measures 75″ x 39″. I recommend staying close to these dimensions in order to use a standard twin mattress, standard twin sheets, etc. I will note, however, that I did make the top of my playhouse bed loft 72″ x 36″ and a mattress fit fine up there.

Step 2

Cut your plywood equal to the distance figured for C as the width of the plywood. Cut the length of your plywood the distance of A – 1 1/2″. In this example, B = 72, so the plan shows the trundle to be cut at 70 1/2″. C = 38 1/2″, and the plywood is cut at 38 1/2″. (Also note that these are the correct dimensions for a storage trundle for the Simple Daybed.)
Attach the ends, as shown above. This example shows the use of 1x8s. For a deeper trundle, you can use 1x10s (if your bed has at least 10″ of clearance). Leave a 2″ clearance under the plywood when attaching the trundle sides, this is shown above. Use the 2″ screws to predrill through the trundle sides and screw into the bottom. If you are using MDF, make sure you predrill the entire depth of the screw and use drywall screws NOT wood screws. Avoid screwing within 1″ of the end edges of the MDF.

Step 3

Attach the Trundle Sides. Attach the trundle sides in the same manner as step 1. However, make sure you also screw into the end edges of the trundle side ends.

Step 4

Caster Wheels. Worried about the middle of your trundle sagging? Don’t be. This trundle is not going to sag. Add trundle wheels to each of the four corners and two wheels in the center of the trundle, as shown above. The center trundle wheels will act as a support and prevent the center of the trundle from sagging.

Hi ana! I built this a few months ago for my girls who share a small room. I used the simple bed plans for the footboard and headboard. I didn't want the height so high with the casters, as the current height was already overwhelming the small room. After much thought I found a solution! We used gorilla glue to attach several furniture sliders to the bottom of the trundle (we have carpet). Several months later and it still works wonderfully (as was very inexpensive)! It pulls in and out with ease! Thanks for all your great plans! I'd attach a picture but a) the room is never that clean and b) it's hard to get a picture due to the size of the room and placement of the bed...

I am just getting into DIY, sewing and building . I really want to build a pop up trundle for my little girl's room . I can't find any information on the internet but to buy one . Any ideas ???? That would be magnificent and much appreciated by me and my two little girl's . :-) What I'm looking for is how to make the pop up frame part ... Do you think just building a frame with criss cross legs and a locking mechanism would work ???

Do you have plans for the actual bed? This is exactly what I've been looking for my sons big boy room! :)
