As a 62 year old woman, I was very impressed at how easy it was to put the radiator together: great instructions and well ordered pieces and required fittings.  I  put the cover together in 40 minutes...lifted it and carried it through to the bedroom very easily.
From having a stark, white, old and ugly radiator just talking up space in my freshly painted bedroom I now have a really lovely looking piece of furniture that fits well with the rest of the room...plus a useful surface to use.  I am delighted!
