Heavy guy looking for Any advice on adjustable bed or big wide well built recliner. Sleep number 360 any good?

I have a a bunch of back problems and when I lay flat, my back sorta locks up. So I’ve had to sleep in a recliner mainly. The mattress I have is really hard to sleep in unless I prop up pillows a lot and even then. I seen the sleep number 360 beds that can adjust. Any suggestions? I tried to look for a recliner r/group but didn’t find any. I’m looking for any advice on recliners that are wide and hold up under heavy weight or a bed that’s not junk that would work. Thanks
