I really like the idea of the support thing in the Out'nabout carrycot. It's a bit like a strap, but way more comfortable. Does it come attached to the mattress or the carrycot itself? Does the carrycot for the Nipper double have this? Are there other brands who have this too? Do you have universal ones? Or can you buy it from Out'nabout and use it in your iCandy Peach AT?
