A surprisingly comfortable mattress for the price! Arrived rolled up and have to admit I was very sceptical that it would ever resemble a king size mattress. However, within a few minutes of opening the packaging, the mattress  began to take shape and within an hour became a perfect king size. We expected it to take a few nights before we got used to it but we both slept like logs from the word go. So, all in all, very happy with  our purchase.
