Arrived missing parts. Does NOT have any lock for the various positions; it relies entirely on friction with the bottom plates. So if you have a thick, stiff mattress like ours it will not stay in a sofa position unless you sit on it to apply pressure down. As soon as you stand up, the pressure from the mattress overcomes the friction at the bottom and it slides out to a bed. Very annoying.
