I'm trying to avoid a 5th leg in the middle of the bed, for aesthetics and because I don't want it in the way of cleaning.
If the plywood needs more support, I was planning on a third rail running lengthwise down the center of the bed, and maybe a center leg at either end of it.
Ideally, If I do use the third rail, I could use 1/2" plywood, for weight and cost savings.
Any feed back would be greatly appreciated.

I think you have answered my question.
Even across 60 Inches, 3/4" plywood isn't enough.
I was hoping 3/4" plywood was enough because that is how thick the slats on a queen sized bed are.
Further review shows a middle rail , even on the models with out a center leg.
With this in mind, four 2 x 4 's , set on edge ,running lengthwise, should be enough support either for slats or a full platform of plywood.
I prefer to run them lengthwise rather than across the width of the bed, to avoid wasting wood.
8' lengths are the most efficient buy for me, and would give me a platform long enough to hold the mattress and give a place to sit while getting dressed/ undressed.
I have doped out a cut sheet for a 4' x 8' sheet of ply wood.
After accounting for the 16" x 60" seat at the end of the bed,I think I can get thirty-four 4" x 30" slats from a single sheet.
By laying two of these slats end to end across the four 2 x 4's, I should get a surface made up of 17 4" x 60" slats with one inch of opening between each slat.
I plan on one 2 x 4 along each edge, but I question the placement of the other two.
I could put them 20" in from each side, leaving each individual 30" slat cantilevered 10" into the center.
Or , I could run them side by side down the center, 30" in from each side, with the full 30" span between.
Honestly , 5 parallel 2 x 4 , 15" on center is probably the right answer.
