Are memory foam mattress toppers right ?

been looking at 3cm gooey memory foam mattress toppers but don't know how good it will be on a sprung mattress.

Answers: It will be comfortable, keeping within mind that memory foam gets hot as you sleep on it. It reflect your body heat.

amazing, we hold one, we have a crap mattress and the foam on top add that bit of extra comfort, the only problem is getting out of bed surrounded by a morning!
