Casper—a brand that’s considered the connoisseurs of bedtime essentials—is hosting a day-long event filled with conversations and explorations surrounding the activity everyone is familiar with: Sleep. Have you heard about the Slowave trend? (We haven’t either). Well, you can learn all about it during a special panel, including other discussions led by keynote speaker Arianna Huffington (author of The Sleep Revolution: Transforming Your Life, One Night a Time). Special guests such as Reggie Watts, Michael Rapaport and Benjamin Walker will be in attendance, too. But the best part? The talks end with an open bar and DJ Set by St. Lucia, so you’ll certainly be wiped and ready for a good night’s sleep after an evening of cocktails and dancing.
