TravelChair fashions light, foldable camp chairs using durable materials, and the Bubba?s deep seat can support bodies up to 300 pounds. Each throne?s double-coated polyester seat is reinforced to resist tearing and stretching, and oversized, solid nylon feet keep the contraption from sinking into soft soil, sand, or backyard butter pits. Groupon holders can also choose to adopt a junior member of the TravelChair team, such as the Sidewinder?s tripod stool, which cushions tushes with closed-cell foam padding ($20). Or, sitters can snag a self-inflating air-foam cushion to buttress butts atop TravelChair thrones or space-shuttle ejection seats ($15). Shipping is not included with today?s deal.
