Best divan for 93yr old

I want to treat myself by replacing my 35yr old single divan that has gone very soft and bouncy but I'm confused by all the advice and to be honest I don't have the inclination to do all the comparisons for each component. I just want a new single divan with no drawers, medium support but very good quality to ensure my comfort. Please can you suggest a few specific beds so I can look at them? Thank you.
