These are very comfortable Adirondack chairs but they are not going to last more than a few years. The slats on the foot extension are not as thick as the seat. I’ve already had one of the extension slats crack and I only weigh 170 lbs. It’s a shame they shortchanged the materials because it’s a great design otherwise; flexible positions, clever extension option. It would be better to use the same thickness slats on the extensions and charge another $10 per chair.
