I’ve recently been diagnosed with a potentially serious back issue and replaced our suite with a couple of Ercol sofas- a 2 seater and a 3 seater. They were more expensive than I would have liked - about £2600 for the pair once I factored in Scotchgard and delivery - but were by quite some margin the most comfortable and supportive I tried across a wide range of sofas, and everyone who has sat on them over Christmas has said how comfortable they are. As a brand I’d say they are worth considering.
