We have a pocket sprung mattress / divan with this mattress topper on top and it's absolutely heavenly. That said, I would really like a super kingsize bed (ours is now getting on for 12 years old and when you remove the topper you can see where the mattress sags a bit!). Haven't quite got my head around what to go for yet and may start a thread at some stage! Would like to go for the same again but they don't seem to exist anymore and the mattresses and divan bases seem to have grown in height over the past 12 years. All the mattresses seem to be 30cm deep, not 20cm and the bases have grown too. Although this may make them extremely comfortable I believe our room may appear to shrink somewhat once we put in a new superking, extra tall bed in the centre of it!!!
