Oswerpon 23" Wide Heated Massage Stadium Seats for Bleachers with Back Support, Portable Stadium Chair with Armrest, for Outdoor（Without Battery)

This Oswerpon heated stadium seat with back support reaches a maximum temperature of 130°F and is powered via USB, requiring a 5V3A power bank or higher to operate—though no power bank is included in the package. The backrest features a vibration massage function with six total levels, combining three intensity settings with two distinct modes to soothe tired muscles during long events. A dedicated lumbar support pillow is included to promote healthy posture and reduce lower back strain throughout extended seating sessions. The seat offers flexible width configurations: 18 inches with armrests raised for individual use, or 23 inches with armrests lowered for extra space or connecting multiple seats together. Constructed from waterproof polyester and rugged 600D Oxford cloth, this chair withstands the elements while remaining easy to clean and maintain. Two securement methods—a bottom strap and dual hooks positioned below the seat base—ensure stable attachment to bleachers and prevent unwanted shifting. Each package contains one 23-inch stadium seat and a user manual to guide you through setup and operation.
