It looks like the cushions are unwrapped correctly, but there’s a bunch of small UV islands that I’m not sure what they go to, if they’re part of a larger piece then they would get better results by attaching them to the larger pieces. As for the frame, it’s long and in some cases you might have to add a loop in the middle so you can split long skinny objects in the UV’s to make better use of the space.
In other UV news, the new 2017 version of 3ds Max has a big UV editor improvment which includes better overall tools and improvements with the algorithm for unfolding and for packing. It also works much faster with objects with high poly counts.
