To the spouter who said the crest switched from wood to metal stands because of female guards, you have to be joking. You should fact check before making such a statement. The aluminum chairs are more cost efficient, easier for BOTH men and women to move, and most importantly they last longer and are more durable than wood. Do your research on conductivity and lightning. Also if you actually knew about lifeguarding, you’d know moving the stand isn’t about strength it’s about height mostly.
