We didn't want the same one that we had, and we didn't really want a pocket sprung mattress either. Been there too, great until the buttons start to go.
So, on Tuesday we went back to the Back specialist shop, and tried out their range. We were there for some time, as we wanted to spend enough time on each mattress to get a proper feel of it. The assistant took pics of my spine alignment so he could advise on which mattress was best for my poor back.
By the time we'd tried them all once, and tried three of them at least twice more, DH and I had an idea of what our preference was. We asked the assistant what the spine analysis showed. Rather surprisingly, his appraisal of suitability matched our preference.
So, we ordered our preferred choice. It's some gel thing, which I am hoping will have the additonal bemefit of helping keep me cool when the menopause strikes (which will be in the lifetime of this mattress)
That night the current mattress seemed even more uncomfortable. or so we both independently imagined.
The delivery firm phoned on Wedensday to arrange delivery for today (Friday). Wednesday was uncomfortable. Thursday arrived , and I was thinking "only one more (lack of) sleep".
The new mattress arrived today, and it's on the bed now.
Apparently it can take some weeks to wear in, so we might not be getting the immediate relief we were hoping for.
It's also actually two single mattresses in a superking cover, which I really wasn't expecting. Apparently that's standard for this type of mattress, if it's over 5 foot wide. Hmm. Hope that's not going to be a problem.
