After tons of research on the best platform bed, I chose this queen model.  Its incredibly well made, easy to assemble and perfect for me in every way.  I don't think I could have made a better choice.  The solid wood frame (rather than being flimsy) is very impressive. The slats were more substantial than I had anticipated (having had previous platforms with chintzy slats).
I will be using this platform with an 8" futon mattress.  I actually wanted a platform without a headboard, because I have my own, so the fact that it has no headboard was not a problem for me.
