Slid it up front.. Now everything is back in place. Insulation under the plywood platform, painted platform and the den-dry air flow under the mattress.
I use a ratchet strap to roll it up just enough to remove the mattress. Try to take care of everything to avoid repeating the process.
While your at it, consider a moisture barrier like Aire-Flow, I also added a mattress encasement.

That can be done but all hell can happen if you are not careful....blinds drop...string disappear.
I have answered your question that you asked in another thread.

I am up next to try my hand moving mattress to work water pump and actuator install. Finish by adding a mattress air barrier to avoid mold. 2014-19. David
