With the Big Joe zip modular bean bag chairs, you get to create your own seating configurations by zipping together as many pieces as you like. Unzip to use each piece alone, or zip together to create a chaise, loveseat, sofa or sectional. Even better, these tough pieces are virtually indestructible thanks to the waterproof, stain and tear resistant SmartMax fabric in a neutral shade of slate. And since these chairs are filled with patented Ultimax Beans, they are loftier, longer-lasting and 20% more dense than the average bean bag. Big Joe Zip Modular Sofa
