Picked these for the low profile. The comfort, nice leather and beautiful blue gray color is wonderful! The legs and cord are attached under the couch, definitely easier to assemble with at least two people. Didnt come with an instruction sheet but we were able to figure it out without too much trouble. The head rests can lay completely flat or be positioned in a number of ways from straight up to almost completely flat. To position them you just pull them all the way forward and that releases them to lay all the way back and then you can lift them into any position you prefer
