Recommendations for a good cotbed mattress needed!

[coffeecake]

Ds is 4 but I still want to keep his cotbed as he still fits in it and his bedroom is tiny (bless him). Any recommendations for a good quality (not too expensive) spring mattress?

We've just bought one from Babies 'R' Us, very comfy and not too pricey. My little one loves it.

babymattressesonline.co.uk have a huge range of all kinds including natural fibers and organic covers. They can also make to measure. We have bought two kids mattresses from them and have been very happy.

IKEA, I got a pocket sprung one for £50 I think, there are cheaper too.
