crib mattress - where to buy?

[TinyPenguin]

can anyone recommend where to get a crib mattress from? (approx 88cm by 40cm)
it's for the john lewis Anna glider crib - the mattress in john lewis was quite thin and wasn't really a very snug fit to the frame. Ideally I would like one that is quite thick - compared to that one anyway!

If I recall, Mothercare do made to measure ones (for a price!)

i have used babymattressesonline.co.uk and they are really good. they'll make any mattress to any size and there is a big choice of mattress types.

also excellent for custom fitted sheets!
