where to you get sledges that are suitable for toddlers?

[kissmummy]

sorry if this is on the wrong board..i'm not sure where it fits really. i mean those sledges with a little seat or at least a little back so DS (2.5) doesn't just fall off the back
I can only find one brand, Snow Rocket, but it seems sold out online. you see them everywhere in ski resorts. anyone?

This (ds has a variation with steering wheel) or this orthis to which you can add a seat

Ours came from Sports Direct and dd2 has been fine in it today.

At that age they should be fine in a normal sledge though surely?? My 2 yr old ds sits in ours fine.
