Slumping bed

I have a '12 3740 Infinity 39' fiver which I purchased last year. We have taken the unit out two times this year and the mattress slumps in the middle. The mattress is a memory foam which we thought was probably a lower end model and time to change it out. We bought a new mattress. I started moving the old mattress and when I stepped on the platform at the head board the chip board platform sunk 3 inches. So we didn't have a mattress problem but a structural support problem.



I have two options:
1. take apart the existing structure and build a support under the platform.


2. Leave the chip board and strengthen it with 3/4" birch plywood.


Anybody dealt with this problem? Is there solutions I have not considered?

I went with the next thicker piece of good plywood and I added a couple of pieces of the perforated angle iron to the underside of the bed base as stiffeners. I placed them crosswise where the most weight was concentrated, i.e. hips and shoulders. It made a big difference. You might also have a mattress problem not very good foam in the OEM mattresses. We replaced the OEM with the same foam mattress that we have on our bed at home.

I added support lumber in the middle of the OSB. I thought about going with thicker OSB, but I already had the 1x4.
