Glad I chose metal over wood. (Plastic was NEVER in the running.) These boxes aren’t heavy. However, they seem adequate to last several years. Maybe I’ll need to replace the bolts periodically, but that’s no big deal. Easy to put together, with my son as an extra pair of hands.

In the past I’ve built boxes myself from inch-thick lumber. It was expensive and they were rotten after five years. Believe me, the wooden boxes you can buy online are made from FAR thinner wood. Most will not last more than one growing season. Wooden boxes with walls less than half an inch thick are not planters they’re props.
