mattress memory foam/latex recommendation for person with needs

Hi there,
I'm writing to ask your expertise on a recommendation from your range inc I saw there's new hybrid and other foam mattress's being released soon? I like the look of Origins Pocket Latex 1500 I've spent such a long time researching memory foam beds as for 4 years I've had a shakespeare bed pocketed which isn't that great I think the 1500 is the one I'd like to buy soon just I'm worried it might be to hard for me to sleep on? I'd like to give my details if you'd kindly let me know your view I'm 6.3ft 200lbs and have adhd and a high anxiety level I've read memory foam helps with anxiety and I'm only interested in getting a memory foam mattress preferably a latex or the new hybrid coming soon so the mattress doesn't get to hot, I'll definitely be buying from your site as its the best I've seen out of other reviews and for my needs from what I've read you guys go the extra mile!
