The total of 3/4 ply and the bigger mat is the issue,they need Larger PSI struts! Youroo!!
I for sure need bigger struts, but for right now I just live with it. I just store my satellite dish in there anyways so I don't need to open it often.
If you placed the other plywood on top of what was there why don't you just take out the bottom layer of plywood and screw the hinges in the one you added. Less weight.
If I took out the plywood underneath the head of the bed would be higher. I essentially had to go head to toe with the plywood to keep it even underneath the mattress. Not sure that makes sense or not, with my poor use of the english language?
Don't know what I be done wrong but I had to remove the two 125 lb struts that came with the C and install 2-50 lb. struts. The 125 lb were just to heavy. They ripped up the hinges on the plywood and the plywood would bend when trying to put the bed closed back down. I tryed changing the mounting points several times but just couldn't seem to out smart those darn struts.
For those of you who need higher pressure ones, pull off one of your existing ones and you will find the part number. This part number will correspond with the pressure it takes to compress the strut. I went from 100# to 120# on each side to hold my bed up. The great part about using the same brand you have is you can get the higher rated struts and install on your existing brackets. Just use a flat head screwdriver to pop off the retaining ring on each end and they come right off. Then pop the new ones on. It's a 1 minute job that only costs about $12 a side.
This is what I installed so the lift would stay up with the weight of the mattress. Love it. Lift all the way and set down on the locks, lift up again to release the locks and lower bed down.
Youroo!!
