- i used pine 2×10′s i had left over from another building project. make sure to choose ones that are nice and straight and flat. i used 11 pieces that were 8′ long to begin. that and a few 3″ wood screws were all the materials it took!

- as you can see from the pictures, there are three different sized boards (all made out of the 2×10′s, so 1.5″ thick by 9.25″ wide):
+ the 7 top boards that make up the platform are as long as the width of my mattress, minus one inch. i spaced them evenly, with about an inch of room between to allow air to circulate. the length of the platform ended up an inch shorter than my mattress. the reason for making this shorter in both width and length was to allow the mattress to overhang the platform ever so slightly, so that it visually floats, and so that the corners of the platform are padded.
+ the 2 “legs” are just as long as the length of the platform, minus 2″, so that they set back from the edges an inch on each side.
+ the length of the 2 cross braces between the legs are the the width of the platform, minus 3″ for the thickness of the legs, minus 12″ so that they set back about 6″ from each edge.

- you can also see that i shaped both the legs and the cross braces to add a little design flare, reduce the total weight of the frame, and also create more of a 4-feet platform rather than 2-long rails, which doesn’t tend to rest on uneven floors quite as nicely. i used a bandsaw for this, but you could also us a jigsaw.

- another detail i employed, that really made a big difference, is that i rounded the corners of all the boards after they were cut, before i assembled the frame. can you see the rounded edges? i used a 3/4″ router bit, in case you have access to a hand-router.

so, you should be able to measure the mattress you’d like to make this for, and get started!

good luck.
