We're looking for a zip-link super-king size mattress. My wife is 9st and I'm 20st - we're both side sleepers. She prefers firm mattresses and I'm not so fussy as long as I don't feel like I'm sinking through to the base of the bed (which does unfortunately happen with some mattresses I've tried).
We're looking at either the Origins Pocket 1500 or Origins Pocket Latex 1500 (our budget will not allow the Artisan range), with one side medium for her and the other firm for me.
I wanted to check - does the Origins Pocket 1500 sound like it will give us what we're looking for? The Latex version says it's firmer, but will the medium firmness Latex mattress feel like a concrete slab to my wife?
