Bought in superking size, came rolled up so was easy to lug upstairs, when opening it bounced into shape very quickly and quickly expanded. The only comment I have upon opening is that it spelt of what I can only describe as pumpkin Not sure why but the smell went away very quickly. I left it a while so it could fully expand and when I finally lay on it it felt incredible. The only reason I’ve given 4 stars instead of 5 is because this is only the first day so hopefully it won’t flatten out or get too soft. It’s just the right amount of firmness for me.
