Kids mid sleeper bed & mattress (N8 North London)

Suit age 6-11.
Sleeping level raised 90cm off ground giving space for den/storage underneath.
Bed only, not mattress (regular single size). Currently partly disassembled - see last photo. Largest element (base of bed) is 190x96x10cm.
I got this on this site not too long ago, but it doesn't suit my daughter age 6 with sensory needs.
But its a lovely bed and was easy to put up.
One screw was missing bit I found something else and it works.
I'm using mostly previous owners photos as they are better than any of mine.
