I dunno; I plugged [34" stool] into the Houzz shop and a lot of things came up. not sure exactly what you're looking for, but there appear to be some options. But you might have to prioritize among your features, because I'm not sure you'll get them all at once without some luck.

A lot at this height seem to have cushioned seats, so it may depend on the weather where you live... You could try a specialty place like Mr. Barstool...

thanks for comment but I need OUTDOOR chairs : ) . I live in Indiana.

I have no idea what style you are looking for, but patioliving.com has a pretty decent selection, decent prices and gives like 5 to 10% off the first order.

Overstock has one that is adjustable. http://www.overstock.com/search?keywords=outdoor&taxonomy=sub2023&searchtype=guidedNav&cid=247234&kid=48826975273078&TRACK=PSGGL&mkwid=s48826975273078&pcrid=102855166164&pmt=b&pdv=c&mtrckid=17394at10470&gclid=CLat75fNjM0CFUqeGwodkSkO0w

Why so tall they make getting in and out of difficult when they are this high

If anyone is looking for these, we have 7 here.
