Hoping the fount of wisdom that is Mumsnet can help me with a quest that's proving quite frustrating so far... crosses fingers
I have various health issues that mainly consist of permanent aches and pains (I suspect fibromyalgia, though that's not been confirmed) and I really struggle to get comfortable in bed at night, resulting in poor sleep most nights regardless what sort of mattress I sleep on. I've holidayed a few times in a holiday apartment where I've slept like a dream. The mattress is so soft and marshmallowy I just sink down into it like I'm on a cloud, and although people often seem to say that's not good for pain issues, for mine it seems to be what's needed as I sleep far better than I ever do on my newish memory foam mattress at home (which to my mind is a lot harder than one would expect an mf mattress to be) and wake without aches and pains which is normally unheard of.
Actually went to the lengths of stripping off the bed linen in the holiday apartment(!) to see what make of mattress it was, hoping to buy one the same, but I can't seem to find it on the market. I do know it's a Healthopaedic, has memory foam on top, I suspect pocket springs underneath (as I do feel supported under all the marshmallowiness when I sleep on it), I took pics of the mattress and its label and have looked everywhere online... and they don't seem to sell the same one, or if they do they've changed the appearance/label. Sod's law!!! Even been on to the manufacturers, but they've not got back to me after initially promising to do so, not too surprised as they seem to cater more to trade than individual customers.
I've been testing out various mattresses in bed shops but they all seem a lot firmer than what I'm after. So I'm wondering whether anyone can recommend me a mattress or even just a topper that's really soft/sinkable and squishy?? Have a memory foam mattress topper that goes some way towards recreating the feel, but it's a bit thin and shifts about on the bed.
Keeping my fingers crossed someone can help, and that this post doesn't disappear under the behemoth that is AIBU! 
Thanks in advance...
