I purchased this Hammock for my special education classroom and it is exactly what I needed for my students! The only problem I am having now that I have had it for about four months is that the "s" hooks that hold the hammock in place have become worrisome.  The metal of the base has cut almost all the way threw the metal "S" hook. I will now have to purchase replacement "S" hooks frequently to insure that the hammock remains safe for my students to use.
