This review is from: Safety 1st 35025720, Portable Bed Rail, Length 106 cm (Baby Product)
This rail is great for my son's toddler bed to give him security against falling out, which did happen before.
I have also bought a second one to use on a single bed when travelling, as one is not quite long enough for a very wiggly little boy who can end up at the bottom of the bed. Great because it will fit practically any bed.
The only thing I would say is that it's sometimes a little stiff to expand/contact and the legs swing open when carrying it which can be a pain.
