Stretcher

Hi,

I need a better setup in our 2x2m Oztent when touring fire trails.
My wife and I currently both sleep on the floor on single self inflating air matresses with an !8" space up the middle of the tent for access and gear.
The situation probably would improve greatly if my wife was up on a stretcher with about 12 inches of space below the stretcher...and then we stow gear below.
This should make getting ready for bed and getting up a lot easier.
Any recommendations on stretchers that are EASY and Quick to set up and down, compact, good quality and light.
I guess the existing self inflating air matress will be fine on the stretcher and make for added comfort.
Looking forward to the usual great feed back.
Regards
Joe
