Back seat soft/air mattress for 2.5 gen?

I have a 2013 Tacoma double cab. I am 6’2” I’m wondering is there a good mattress or air mattress that would be good for the backseat??
Folded up or down doesn’t matter to me.
I off-road and going over landing/ camping in two weeks.
Not just that I don’t really carry more than 1 passenger. In rare cases I have 3 I’m considering the double seat delete and keep one.
yes I’m gonna hear some of yall say get a hard shell or soft shell.
Maybe even a bed tent and bed mattress. Bed tent and mattress are my go to but I have a toolbox and that’s my issue.
Suggestions would be greatly appreciated.

 

This is the truck btw.
