Recommend me a cotbed mattress please

[Beewhisperer]

Dd (3m) is getting too big for her gliding crib. We have already bought a standard cit bed but I am so confused by the mattresses.
I know a sprung one will be better than foam but there are so many different types and the prices vary hugely.
Could anyone recommend a mattress that will last well without costing a fortune please?

Ds (now 4.5) had a natural wool and coir mattress from this site: babymattressesonline.co.uk/cot-mattresses
And now has the same on his single bed.
I can recommend them!

I got mine from kiddicare. Sprung one for about £80. Cover zips off and can be washed which is a big help when wee and sick don't like staying neatly on the top of the waterproof fitted sheet!

Thank you. I will have a look at both of those.
