Arrived in a timely manor and puffed up very quickly to a full 8 inches.
There was only a very slight odour and that was gone in a day. 
Particularly liked the zip off cover that’s washable and has a no slip bottom side.
It is a very firm mattress but that’s what the description says and since memory foam does relax over time that’s probably a good thing for us as we prefer a firm bed.
I have a problem with being hot in bed a so far have found this mattress to be fine in temperature.
