Non-toxic foam playmats -- any recommendations?

[Teapotty]

Hello:
I was about to order one of those interlinking-tile foam playmats for my 10 month-old. Then I read that they've banned some of them in Belgium because the foam can contain certain carcinogens. Does anyone know a safe and reputable (and nice looking?!) brand that they can recommend?
Cheers.

i have no idea about the toxic thing,we have some we bought from tesco a couple of weeks ago,they were half price,they may have some in your local store,were £7.50 a pack of 4 large tiles.

Thanks. Yeah, they have similar on Amazon for a good price but then I read one of the user comments about possible chemicals used in making the foam. I then googled it and found some pretty worrying articles (try it yourself on "toxic foam mat" or some such) and so am trying to find ones that are as checmical-free as possible.
