We Swapped mattress to a foam based queen instead of the crappy Simmons king. No issues with platform or the struts.
If the struts are not strong enough
You can move the mounting point to help them Moving the strut straighter makes them stronger to hold up
Move up to a stronger strut. They are sold bt weight they support in lbs and length.
Downside is stronger strut may flip up during travel
I also added more screws and bracing under ours to help the plywood
Livin the dream... Retired!
