They fit my pram nicely - i got the doubles one for the P&T and she even makes one smaller for the toddler seat. We have the bright stripey ones with the grey reverse side for the winter but i love the colours so much that they never get turned! Easy to wash, i just chuck mine in the machine and dry flat over the clothes horse. They are really thick too, thicker and softer than i though they would be, so much so that i never even used the cocoon for dd when she was born cause it was so comfy and padded without it.
