A long-overdue update on the saggy, burst-prone beanbag chairs of yore, Fatboy’s squishable Buggle-Up seats ($349 at A&G Merch, 111 N. 6th St., nr. Berry St., Williamsburg; 718-388-1779) are not to be exiled to the kids’ room or the basement. The oversize 55-by-75-inch sacks, stuffed with a similar kind of polystyrene bead as your old rec-room recliner, are armored in rain-, stain-, and ray-resistant nylon, which makes them a weatherproof fixture for a patio or rooftop.
