Decided to go for the super king in the end. It is pretty big so make sure your room can take it. The headboard and footer take up quite a big of extra room. You can't push it flush to the back wall with the curvature of the headboard which leaves about a 6 inch gap behind the bed. Good in a way as it means you can still access power sockets easily that have been covered up.

The overall quality of the bed is very good and it was easy enough to assemble once I managed to get it up the stairs! It's definitely a two person job.

Very happy.
