Inside this sleek and lightweight chair is a USB-powered massage function that sends soothing comfort through your body. Offering two speeds, the vibe's seat and back will soothe you every time you sit. And, because all bean bags compress over time, you can purchase bean refills whenever you need to bring new life to your vibe. For child safety and durability reasons, we intentionally break off the outside zipper pull before shipment. If you need to open your bag, simply use a paperclip to pull it open. Detailed instructions can be found on the warning label attached to your Big Joe.
