Our room really isn’t big enough for a superking but someone suggested a platform bed to solve the problem of fitting it in (we have a toddler who likes to bed share and a double just wasn’t working!). I can’t believe I have never thought of one of these before, and wish I had bought it years ago! High enough for plenty under the bed storage. 
Sturdier than expected. It’s started to creak a little (just getting in and out of it!) after a few months, but it’s a minor negative against the positives of a solid bed at a cheap price. 4 stars simply due to the noise it now makes, but otherwise would have been 5.
