Absolutely solid construction, I wiggle a lot and it hasn't moved an inch. It says you don't need a box spring and they're right! I only have a four inch mattress though, so if you're like me I'd still reccomend grabbing a pack or two of those eva foam floor tiles and shoving those on top of the frame instead.

I haven't checked if it will attach to a headboard/frame myself.

Was really easy to pull out of the box, unfold, tighten a few wing nuts.... done! Which was great since I don't have many tools after moving out.

Plus? Huge storage space underneath. I've measured about 17" of clearance from the bottom edge of the frame on the outside, and about 18" underneath the main part of the frame. Stellar for shoving boxes/etc underneath!
