My husband and I are not small people and we share our bed with a 100lb dog so a light weight frame was not going to cut it for us.  Just put it together today and so far I am very pleased with what I see.  It was kind of annoying to build, but still got it up in about an hour.  It is phyically light to move so I had concerns but it actually feels very sturdy, it didn't make a sound or have any give when we tested it out with the 2 of us and the dog.  Assuming it holds up over time, this should prove to be a great purchase.
