The instructions are woefully inadequate and poorly written. Anyone with no engineering background or little flatpack experience will struggle. Fortunately my daughter found a video online showing how it goes together. 
Also two of the pre-fitted corner brackets were in the wrong place. I could have sent the bed back but couldn't be bothered with the potential hassle. Easier to refit in the correct position.
At the end of the day, you get what you pay for and it does the job.
