I bought this Mattress a little over a month ago and have been so happy with it! I was looking for a firm memory foam mattress that doesn't absorb too much heat as we live in South Florida and it is hot here! I love that I can't feel when my partner moves or wakes up, there is no sinking towards the middle and it allows your body to sink just the right amount in the pressure areas so that you can sleep comfortably all night. I was researching forwver to find just the right mattress at an affordable price and this one is simply the best. I have had another similar product in the past before (a lull bed) which was twice as much and would retain the heat, I am so happy I went with Sweet Night for our bed now!
