Was rather disappointed as I got the incorrect size, it was too late to send back as I had returned my other mattress and also unpacked this one.  Only realised the different size when it was placed on my bed.  I used it for a few months and swapped it with my sister's new mattress.  
It was a good mattress but somehow the size was wrong, I am not sure whose fault it was. So it was a wasted purchase :(
