There is so much to share in this entire “Kristy” platform bed plan that I had to break it up into manageable parts. That way it doesn’t get overwhelming for anyone (including me). :-) Here is the plan for the middle section including the pull out storage box that spans the full length of the bed. It’s big enough for a Christmas tree!
Now you need to build a middle section that will space your side boxes the correct distance apart and support the middle of your mattress. There is no bottom on this box as the casters need to be able to run in and out. Once you build this 4 sided box, you’ll move your side cabinets in on either side. Make sure you keep the front of the middle section square while you shove the side parts in. There is a back on this middle section but not a front so you can push it out of square if you aren’t careful. Measure to make sure the spacing is the same in the front as it is in the back.
If you are building wardrobe towers on either side of the Storage Bench, you’ll want to wait until after those are built to add the large face on the outside of the entire platform bed as shown in the picture below. If you are not building towers, you can add a decorative face as shown below but have it extend all the way to the head of the entire bed.
Buy your casters before you build the box so you make sure not to build something too high that won’t fit in the space you have. For this long of a trundle, 6 casters are needed.
Build a simple box making sure it will fit easily in side the middle cavity. I have us a little wiggle room. The length of
Roll the trundle into place.
You’ll want to build drawer fronts like you did for the sides that fit the faceframe on the end of the bed. Make one that fits the center space as well and on that one, you can add false bottom faceframe rail (horizontal piece) behind it so it matches the sides.
No one would ever know there is a big ‘ole storage box behind there!
