This box spring is just what I needed that I didn’t know existed.  The fact that no assemblage was required was a Huge Plus!  It is well built, coated and quietly stretches out to its size.  The included box spring cover is also appreciated and will go on more easily w assistance from a friend.  As always, Wayfair has terrific customer service which makes shopping and dealing w occasional returns a business worth 
utilizing.  Thank you!
