When I bought my previous mattress, it literally took me a month or two to adjust to it, it wasn't comfortable right away. However, with this new Sealy mattress, I was feeling great from the very first night. I have a bad back, so having a good mattress is very important to me. I need good support, but if it's too firm it causes me pain, and if it's too soft, then I don't get the support my back needs. This mattress is just right (I feel a bit like Goldilocks). I really enjoy my bed now. I hope that in a year's time I will still feel the same because with a mattress, time tells all.
