It came with all the parts, all the screws and hex keys were there.
The frame is very good quality and my mattress fits perfectly.
When you have completed the build don't push down to close it, it will only close once the mattress is on it and then it will just need that initial push down to close.
The instructions could have been cleaer at some points but take your time and read carefully; it recommends 2 people to build it but I did it on my own, it did take longer but I was totally fine. (me and my partner tend to bicker during things like these so if you're the capable type wanting to avoid a silly bicker with the partner I say this is totally fine on your own!!)
Very happy!
