Leveling bed floor fr carpet?

[BIG ORANGE]

Any idears on how yr leveling yr floor before placing carpet down?
I cut strips of sound deadening and placed those in the low area's of the floor, then cut the same material out and fit itin the bed over the entire floor area then put carpet down.
Unless someone has a better idear, I'm open fr suggestions.
Thanks.

I think that’s probably the best way to do it. Strips of rubber in the slots may work since. I’m lucky enough to have leveling mats in mine. Too bad they aren’t reproduced.
