I received this great outfit and used it for a recent trip at bedtime as we all share a room and wanted him to have his own space to sleep.  It was great.  It is very sturdy and has a locking mechanism to keep it in place once it is unfolded and used.  There are so many out there like this, but this one is the best all around.  I like the added protection against slipping.  My only complaint is that the material is a bit noisy but nothing to bother me I'm happy
