Used double mattress and metal frame. I think both ikea. Has fire label. It looks stained but I've had it with a mattress protector on.
Comes with the steel rail in the middle and both sides of wooden slats - no issues.
I can give you an Alan key if needed to assemble - you connect Width and Length piece and then turn Alan key until in firmly.
Collection from BN2 9XA by tomorrow (Tuesday) 3pm otherwise I have to take to skip
