High sided cot top changer - does this exist?

[WelshITGirl]

I have been researching cot top changers and they seem to have little or no protection against babies rolling over?

I have seen one Mamas & Papas cot top changer that has sides higher than the changing mat therefore providing some protection but this only comes in an unusual colour that would tie me in to purchasing the whole nursery set in this same material (which would be too expensive).

Has anyone come across a good quality changer, preferably in white, that has higher sides than your average changer - thus providing some protection for active babies??

Hope you can help
