So finally agreed on 2k budget, we were going to go as cheap as possible and spend it on a holiday instead but we paid £1700 for our mattress 10 years ago and it's still fab, we are just moving to a king size from a double so need a new one.
Ours is soft/sink in/cloud like BUT is an orthopaedic mattress as we both have sciatica, I don't know how it works but it does! The version of our mattress has been discontinued otherwise I'd just buy the same in a bigger size.
Thanks in advance!
