CakePhP BreadCrumnbs problem

What I did

Hi, i´m working on a website where i have a view where i have a list of mattresses, on every item i have a link to a view/item_id. where i can see the specifications of the item. at the top of the view i will like to put a breadcrumb that looks something like Mattresses > item name. i can make it by adding the crumbs at the begining of the "view" view file, something like:
$this->Html->addCrumb('Mattresses',array('controller'=>'Mattresses','action'=>'index)); $this->Html->addCrumb('item Name',array('controller'=>'Mattresses','action'=>'view/itemId)); echo $this->Html->getCrumbs(' > ');

it works fine. Now, i have a View with a list of different Foam type, and just like the mattresses, i have a breadcrumb to see the speciffications of each Foam type and get something like foams/view/foam_id. inside this view i have a list of mattresses that are made with this kind of Foam. I will like to put a link on each mattress model so the user can go directly to the mattress specifications view (mattresses/view/item_id). now, i´ll like to have a breadcrumb in this file that looks something like this:

Foams > Foam Name > Mattress Name

so the user can navigate easily through the site. but i don´t know how can i achieve this. i don´t know if there is a way to have an stack of pages visited previously by the user.

i tred adding addcrumb on the foam view file but it does not works.

any idea?
