A 440 lb rating per chair is the highest in this group and comes from a heavier metal frame than the backpack styles use. Sponge padding through the seat and back adds comfort that plain sling fabric cannot, and the wear-resistant, tear-resistant cover handles sand and salt. Both chairs fold to 6.5" thick for a car boot. Open dimensions 25.5" x 20" x 19" with a 17.5" square seat. No assembly needed; combined net weight 13 lbs.
