Query: Small, A PAIN to assemble, Not worth the money!

The side rails are much smaller than I expected! I should have reviewed the dimensions more carefully! I am not convinced the "locking" system is worth anything! And this thing was a pain to put together! Some steps are overly detailed and others appear to be missing vital information. There are sentences that are not proper English and make no sense at all. In conclusion, the construction is cheap!
