OK for all you old timers, I don't mean as in it moves and shakes, I mean it's the shiz (the best).
1.- Sealy covered wood base
2.- Sealy independent spring latex mattress
3.- 3cm layer of wool
4.- 10cm of memory foam tapering out from the centre to the edges... I did this, as it would sink too much and lift the edges making it hard to move around
5.- 2 thick sheets in the centre for more centre support
6.- 2 wools dunas (when it gets cold I'll remove 1, <10c I'll use both)
7.- 4.2kg of 95% duck down.
Top that!
Also cos it's sooo thick, only really top quality 1200TC sheets will cover the lot (and not rip).
Now you may think that the above would make it really soft... well it's soft and firm... I hear it calling me again 
Yeah, but, those plastic under lay sheets make a lot of noise when you roll over.
