Yes mine was a double, the brackets join the two base units together.
What are the base joining brackets? Didn't seem to be anything like that fitted on my bed. Just had a thought, was yours a double bed?
Don't know, it is for my 2 year old grandson to sleep on now and then. However, I did lie down on it and it felt very comfortable.
How comfortable was the bed in the end are people happy?
Similar to the previous post, the delivery guys did a sterling job for me, fitted the wheels and the base joining brackets. No complaints, first rate service from John Lewis.
