Do you need to buy mattresses for carrycot attachment to pram?

[spook14]

Hi, not sure if this is the right place to post this but bear with me!
I'm 33+5 with twins and have taken delivery of my pram which is an icandy pear. The seats convert into two carrycots for new borns, which I've done in anticipation.
My question is, do I need to get additional carrycot mattresses to put in the pram or does the fact that its a carrycot suffice?
Didn't have this trouble with my first singleton pregnancy, her pram was self explanatory!

oohh congratulations! do it not come with something, my jane pram did but that was 5yrs ago, the silver cross one am looking at now also does

would think its pretty standard? have you checked the website?

when you watch the video of it, it certainly looks like it has a mattress in the carrycot bit - shows as having a white inside
