I can't even access the original link posted, every browser I try gives a secure connection failed error, that it exceeds maximum permissible length, I tried with 4 different browsers. I got the same message when I shortened it to just the main domain and gave up.
But now that I see what you're talking about, I love those types of seated arbors and wish I had space for them. If I lived in a climate where I could keep flowers going year round in them, I'd definitely find a place for even a few. I had looked them up once before at
Amazon and found a bunch more reasonable, but still no place where they wouldn't really be in the way for me.
