Lovesac has opened its doors at Westfield Montgomery Mall, selling beanbag-style furniture on the second level near Nordstrom. This is the second beanbag store at the mall, joining two-year-old Yogibo. Also new this week: A try-it-yourself kiosk for Peloton, the high-end line of spin bikes with video screens that connect to live instructors. You’ll find Peloton on the mall’s lower level near Guess.
