Thanks for the tip on moving the struts. I moved them today and it made a difference. I moved the end under the mattress about 2" which kept the bracket on the little plywood block it was screwed to and moved the frame end about 4" toward the foot of the bed. This made the struts more vertical and when I piled all the bedding at the foot of the bed it held up. Of course we just bought a foam topper... so hopefully that won't be too much. If so I will have to move the little blocks. Our struts are labeled 80 lbs each.
The first photo shows relocating two of the screws that hold the block to the mattress platform and the bracket moved to the opposite end of the block.
The next photo shows the relocated base bracket. First I only moved it 3" but then had to move it another inch.
I hope this helps anyone else with this problem.
