Buying these shitty blow up mattresses every 4 months is starting to get kind of old. Unfortunately a real bed cost some money which I don't have much of right now 🤷🏾♂️
I would just get a cheap mattress. And start slow until you can work up to a bed. You might be able to find one online.
Like Amazon.

In the hot weather, I can't stand to sleep upstairs, so I use either a sofa or chair downstairs. I tried air mattresses years ago but decided they're too much trouble. You might check consignment and antiques stores, if there are any in your area, for used beds. I once bought a twin bed in perfect condiiton for $50.00 at a barn sale.
You don't have a couch? If you had to skimp you can buy a twin mattress and put it on the floor. I did that in my 20's when I was broke as hell. I have 3 ferals that I domesticated one at a time. I would sleep on the floor in a spare room in a sleeping bag. I had friends who were broke that had a futon instead of a bed.
Check out furniture outlets, they often have the same top brand names at half price or less, brand new. Three years ago I got a $1,200 queen set for $499.
