Bests & Worsts Reviews from Amazon

I originally wrote a review that was not favorable because upon receipt - I had a knee jerk reaction to how big the rolled mattress appeared (It hung over my bed) and I was worried that if I unrolled it and it truly did not fit -I would have to return it - and how I would manage that on my own - it was a bit heavy for me to drag up my stairs. However, after 16 hours of having it unwrapped and unrolled, i can see that it's snug but it does fit and the sofa bed folds back easily enough. I do not feel the bar when I lay down on it and am quite happy with it now. There is a slight plastic smell from the foam rubber - I'm hoping that will go away - I'm leaving the window open and the bed open so it can air out. Does anyone know how long it takes for that smell to go away? It took no time at all for the bed to decompress. And I could see that the extra material I thought made the mattress too large for my full size sofa bed was so it could expand upward. But without any instructions or a product description attached, one might not know this - I would suggest having a product description flyer that says, allow xx amount of time for it to expand, xx amount of time for the smell to dissipate and that the mattress material overage is for that expansion.
