Replacement mattress for a city select baby jogger pram

[RaisinGirls]

I have very kindly been given a second hand pram for my 6 week old baby - a city select baby jogger. However, I would really like to replace the mattress with a new one. I have tried googling it and also looked on city select's website but can't seem to find anywhere to buy one.

Am I being a bit dim? Can anyone help me? Sorry, terrible sleep deprived baby brain going on at the moment.

thanks in advance

Hiya, I have come across this website which makes mattresses to fit virtually any carrycot or cot:
baby mattresses online

They have a [[http://babymattressesonline.co.uk/made-to-measure-mattress-for-baby-2 listing] listing for the city select carrycot.

Lots of choices regarding materials etc, and made in britain too :-)

Sorry the second link should be
city select carrycot

Thank you x
