Another editor-favorite choice that's become a new hit is the newly released standard-size Marlow Pillow ($65). Unlike any other pillow of its kind, this one is a two-in-one design, all thanks to a handy zipper. Launched by Brooklinen, the brand spent years developing the "perfect pillow." Its unique zipper design allows the user to adjust it to their own firmness level quickly and easily. When the pillow is zipped up, it has a denser feel to it, and when it's unzipped, airflow reaches inside, giving it a more fluffed-up and light feel. Customers rave that both are great for side sleepers, and this way you have the choice of your thickness level.
