Love the colors and quality of the fabric.  I believe I read in the Q&A that these do not have zippers, but they do in fact have invisible zippers for removing the covers. They are, however, quite thin.  I believe the description said 6 1/4" wide--maybe if you're scrunching them from the top! They did fluff up a bit but still not very thick. It's certainly possible to replace the inserts with a better, thicker  quality.  Still love them!
