I bought this product for my 11 month old for when she has a day at Nanas house in the travel cot on a Thursday. She hated that cot, screamed like a banshee and would not sleep AT ALL. I was about to give up on having a day to get housework done properly when i had the idea of one of these types of mattresses. well. it fit in my mothercare travel cot that's 5 years old just perfectly. It was delivered in blue plastic wrap and then more plastic wrap underneath but I was pleasantly surprised at how soft but firm it was. now came the test. I put her down and she slept for two hours. hit. I love it, she loves it, nana loves it, I have my day to myself and would recommend this to everyone. The only thing to note though is its great for us because this travel cot is static for us, but this mattress does not fold down or in half for travelling, it would have to be packed in the car/stored away as is. as long as you're happy with that then this mattress is a must have!!!
