I bought this for my small son when he was 18 months old. It isn't nearly as good as I had thought :( It certainly hasn't stood the test of time and we have only had it 6 months! One of the springs went and it had sunken on one side :| Admittedly, bunk n' beds were most compliant and sent me a replacement within a very short time frame. Although I now feel very disheartened and wish I had spent more on a mattress as I fear this one will definitely not last at all. I will never buy a mattress online again. Unfortunately I do not recommend this product.
