Make a 1 X 8 frame for the size mattress you want.
I bought a queen sized ... AIR MATTRESS
That's right, you heard me.
Here's the comfort ..
I got a memory foam pad from walmart for 100 bucks.
Put that on top (with a blanket or two between air matt and the pad to prevent sweating)
Blow it up to your "sleep number"
Play with the pressure and you'll sleep like a baby
Welcome home, bro.
Jim-
Welcome home!
Knarf-
I found the same thing, except I got a 2” thick mattress pad-thing from Ikea to put on top. Best bed I’ve ever slept on, as far as I can remember.
