Great bed. We bought the Superking size, and are really happy with it. Delivery was incredibly fast and the delivery guys were lovely. The box it came in was much smaller than I expected, couldn’t believe there was a Superking bed in it. Assembly was really easy. All the parts were clearly labelled, and the handy ratchet was so useful. Just a tip, don’t remove the backing paper from the metal slats until the slats are in place.  First night sleeping on the bed last night, and it’s really sturdy, with no creaks. Under the bed, there is loads of clearance for storage. We’ve put flat shoe crates under there. 
All in all, this bed is near perfect. Two very happy customers here.
