Mattress help please everyone?

Hi everyone,

I'm looking for some help choosing between the following two single mattresses.

1) Pocket sprung - http://www.mattressesworld.co.uk/p/Rest_Assured_Classic_1000_Mattress.htm

2) Pocket sprung with memory foam - http://www.bedroomworld.co.uk/p/Sleepsecrets_Memory_Pocket_Tuft_Mattress.htm?affiliate=gbase

Both are roughly the same price - the first one has 1000 pocket springs whilst the other has pocket spring and memory foam HOWEVER IT does not state it has 1000 pocket springs!?

Also is a layer of reflex foam any good like the following link??
