Feathers collection is my first take to creating the most comfortable sofa in the world.As the centerpiece of your house, The feathers deserve and need to have what a high-performance luxury yacht needs in mid-sea, comfort, style, and materials. The Feathers materials are similar to those I used for the X7T 170ft yacht. 7 Inch, deep memory foam, and a thin layer of GLM glue, so they stay in place forever. Then I coated it with high-performance water and stain-resistant coating on the foam and the outer fabric. Let your wine spill or your dog saliva get all around the cushions, this material is protected from all incidents. I made the feathers livable, sexy, and of course, comfortable.
