Honestly....?
How's it sound when your balls come off the rail?
Just looking at the picture, I'm going to guess that as you run your fingers along the nose on your cushions you're going to be feeling a kind of "wavy motion".
Is there space under all of your rails or just this side?
Side pocket folds are too thick, so it's got your rail off the bed a bit, they could have tightened up the folds a bit better, and not stretched down the face of your cushion where they were stapling.
Looks like 90% of the tables out there. (shrug)
How did they do on the bed and pockets?
Did they level with a carpenters level or a machinist level?
But the most important thing is..... does it play well?
