Mattress for tall, 17-stone man

Hi Mike et al.,
In February I wrote asking about mattress recommendation for a 17-stone 6'7" tall man (myself). In the end I ordered a "Leesa mattress-in-a-box" based on a friend's recommendation. It is not fit for purpose for me. You had recommended that I look at the Artisan Naturals, Artisan Bespoke, and Artisan Bespoke 004 mattresses; unfortunately these are/were beyond my budget. I have been looking again at the JR website, and am wondering if you might have any additional recommendations? In particular I am wondering if the Hybrid 5 or another model might be a suitable alternative (I tend to be a side-sleeper). I looked also at the Origins Pocket 2000 - though I'm concerned about the relatively short guarantee period for that. Also, I think I'd a like a mattress that's a bit deeper. Also looked at the Fusion range, but am not clear as to whether that might be appropriate. The Leesa people are coming in the next week or so to pick up the unsuitable mattress (definitely not a mattress for tall and/or heavier people), so I'm getting ready to order its replacement. I couldn't even sleep on it one whole night through because it was so uncomfortable. Sorry in advance to be a bother. I genuinely appreciate your website and your YouTube videos, BTW! Many, many thanks!
