Delivery was fast , left it unrolled for three days before i slept on it , and have to say it is very comfortable for me, everyone is different and what does for one doesnt always do for another , so , if u like a firm feel ,this is for you. I suffer from bad back and nerve pain due due spinal surgery , this will not be cured, even by a mattress, but it is better than my old one which was a relyon brand.
