We bought this when we ordered a 12-foot trampoline because we live in Southern California and the sun tears things up here. We wanted to protect the new trampoline and give the kids some shade as well. Unfortunately it’s just too smalltight to stretch over the whole thing, even though it says it’s for a 12’ trampoline. And the box was badly damaged when it arrived (and I obviously expected this to fit just fine), so I threw that out, so returning this cover is no longer an option. What a waste. We’re all very disappointed.  Now I see other reviews that say the same- that it was too small. I should have read all of the reviews before purchasing.
