Get the Wet Okole seat covers!
I have the split bench and my console lid would always slam down when I didn't want it to. After I put my Wet Okoles on, it stays up till I say so.
Of course I'm sure there's a less expensive way to fix the problem. It seems that by adding the material back near the hinged part of the lid, it doesn't have the freedom to fall shut. Maybe start looking at it that way and you can install felt strips or something to create some "snugativity" back there.
