Any mattress in the 'few hundred pounds' category will last only a few years maximum and will slump over time, no matter how comfortable it is to start with.
We have a silentnight pocket sprung double in our spare room, and we sleep on Vi-Spring at ten times the cost. I can honestly say from a comfort perspective both a comfy as each other. But the silentnight gets barely any use.
You sleep in your bed 8 hours per night, every night. And by the time your bed also becomes your private internet chamber, the 8 hours becomes 10 hours.
That is where you notice the quality difference. I have no doubt our Vi-Spring will last the full 30 years for which they are now guaranteed, whereas a cheaper mattress will simply sag fairly quickly.
A quality pocket sprung mattress will ensure you and your partner sleep without any impact on each other (whether you want that or not, fnar, fnar).
I can be a right old tight arse sometimes, but one life lesson I have learned is buy the best mattress you can afford and match it with a good quality mattress topper. We have had our Vi-spring 8 years now, and with a good mattress protector it is as good as the day we bought it, and supremely comfortable.
It baffles me why someone would spennd £3.5k on a modest Tudor watch, and £300 on their mattress they spend one third of their life on.
