Bedding

Hi all , I have read a lot of posts here , but I have not seen much in the way of bedding. I am in the last stages of my build & am on the lookout for something. I have 45 inches from wall to wall & find that a twin mattress is too narrow & a full is too wide. What have others used? I would like to use a spring mattress . Any suggestions??
I have read that air beds are not very comfy, I find in my advancing years???
I would like more support.
