I love this bed: put a new mattress on it yesterday, and it is great! The platform portion is 5 separate sheets of engineered wood, and they make no noise whatsoever when you move around on the bed, which is a great change over a traditional boxspring (which is unnecessary with the platform). It even has two extra center supports in the queen size. Very happy with it, took my brother in law about  11/2 hours to put together for me.
