Mattress for a rocking cradle proving v elusive or pricey

[ChunkerXmasCake]

I need a square-ended mattress for a rocking cradle we've inherited. Can I find one? Can I feck.

It's 83cm long by 45cm wide (max) but could be a cm or two smaller either way (no bigger).

Anyone know of a site called herehunkerthismattresswillsuityouperfectly.co.uk or similar?

And a small rant...

On Mothercare's website, if you type in "mattress" you get a squillion pages - OK, fair enough...but all of the same kind of mattress (foam, sprung, super-dogs-bollocks, etc) have the same description - no mention of size of them, oh no, that would be too simple. So you have to click into each bloody one to find out how big they are.

And Mamas and Papas? Oh, they have "cot" "crib "carrycot" "TT850" (wtf?!) but no mention of how big these things are on their bloody site, not without clicking into each poncily named bit of overpriced furniture in their range.

And if I see one more fecking Barney the Giraffe or whatever the feck his name is - why oh why oh why do they make nursery furniture so fecking nauseating?!

Don't think mothercare have suitable, closest is 84 x 43
