Absolutely brilliant!  Having it delivered in two boxes means it could get up the rather small twisty staircase into my flat.  It was very easy to put together (though I'm not sure how easy it's going to be to take it apart if I ever move).

You need to have a fair amount of oomph to close the leg rest into a locked position but this isn't a problem for me.

The massage function is a strange sensation but actually really nice.  The heat is gentle.

The only "criticism" is that the power lead could do with being a bit longer but as it happens in my room it's the perfect length and I've covered it with a small rug.
