I've waited a couple of weeks to write my review as I wanted to check that I wasn't just enjoying a 'honeymoon' period with it. I'm thrilled to say that I am still finding this to be the most comfortable and supportive mattress I have ever slept on. Two things particularly impress me - firstly, having had neck pain for some years this is definitely easing as a result of sleeping better. Secondly, as a 'woman of a certain age', I often overheat in the night and I definitely find the mattress helps me to stay cooler. All in all I have been very happy with my order and the friendly manner with which your company answered my delivery queries. P.s. I have subsequently ordered my daughter a topper for her terrible bed at university and she loves it!
