Most of what goes wrong with an order in this category traces back to one of two details. Neither is complicated, and both are on the product page already.
Planter volume matters more than diameter
A wide shallow pot holds less soil than a narrow deep one, and roots go down.
Weather resistance is only what the supplier states
Where a page is silent, treat the piece as needing cover through the monsoon.
Why we publish it this way
We measure the folded size of every chair before it goes on the site, because that figure decides whether it fits through a flat door and into a lift.
A blank field on one of our pages is deliberate. It means the supplier did not give that number, and inventing one would be worse than leaving it out.
