Query: Simple to use and durable

It took about 10 minutes to assemble and then 20 minutes to setup with adjusting it to the bed. I did this by myself, but probably could have been faster with two people. Our daughter sleeps in a full size bed and has woken up many times against it.The bed is slightly raised which worked out well as that allowed the rail to fold down flat and not jut out from the bed.So far we've had it for ~3 months and it's shown no signs of wear. My daughter has leaned on it while standing in bed and it did not give a little.
