I have one of these pushchairs for DD. However, we have a cosytoes from John Lewis, a universal one, that just doesn't fit the pushchair. You can put it on, just, but she has only just had her first birthday and is not particularly big and the straps have to be at their longest and are still a bit tight on her. I had this problem with my old hand-me-down Bebe Confort Loola too when using a cosytoes, but know a problem with that pushchair is short straps.
Is this just the problem with cosytoes, or if I buy a proper baby jogger one will it be more suitable?!
