First, this is really more of a black than a dark grey. Our room is a pale yellow and even in full sun this comes out looking black. That's okay as our accents are black but if you want grey go with the lighter color. Also, this doesn't attach to a standard queen frame. This really is made to attach to the Inspire Q sideboards and base board or foot board. When this is against the wall with a standard queen you can see a tiny bit of the metal, where the side boards would attach, sticking out. Overall I'm happy with the quality and with bedding on the bed it covers all the flaws. The height is nice and this seems easy to clean. However, there are those couple things you should be aware of. You can order the sides and a base board without having to have a footboard and I'd probably recommend that for this particular bed. Unless, like me, you can cover it with extra stuffed bedding.
