Wind Chair Mark I incorporated only the high rise wind block back extension. The extension fabric was made from a defunct camp chair, with pole extension sleeves and grommets already in place. The back extension works well in the wind, either for or against; back to the wind for chill protection, or facing into the wind to funnel a scant breeze swirling around my head.
Mark II winter version uses a piece of Ridgerest pad to keep my arse warm. The effectiveness of which is best noted when the day warms up and my butt gets sweaty.
Mark III desert and beach version incorporated a golf umbrella, to keep me shaded, wherever I choose to sit, even in treeless environs.
Those are all well and good improvements, but with only a single pole sleeve for hi-back extensions or umbrella shade on each side I had to make a choice; either sunbrella overhead or high rise back extension, which also provides significant shade protection.
The naked umbrella shafts and hi-back extensions using Eureka tent poles are essentially the same diameter, 9 / 16 inch. The interior diameter of a piece of 3 / 4 inch PVC pipe is just over 9 /16. Perfectly sized for either tent pole extensions or umbrella shaft. I had an idea to accommodate both the back extension and sunbrellas at the same time.
I dithered about how to best attach a pipe sleeve to the chair frame; machine screws and nuts, maybe cut out a reveal in the pipe for seating the head of a pop rivet tool. And, in eureka moment, realized that a couple of self tapping screws, through the PVC pipe and self-threaded into the metal backrest frame would be easiest thing to try first.
Starting experimentally with an oversized camp chair that is on its last worn out legs, just in case this eureka idea proves a failure.
A 5 inch piece of PVC pipe and two 1.25 inch self-tapping screws. Drill a couple holes in the plastic pipe, a little countersink on the plastic so the screw heads sit flush and screwed self threading into the backrest frame.

Dang, that took only minutes and is rock solid as a sleeve for either the backrest poles or the umbrella shaft. Or, more importantly, both at once.

Oh heck yeah, a length of 3 / 4 inch PVC pipe is less than $3, and I want a two 5 inch aux attachment sleeves on the back of every chair. One on either side, so I can move the umbrella side to side for best shade coverage while still using the high rise back rest in the original pole or fabric sleeves.
I am convinced. The usual production run methodology; cut ten 5 inch pieces of PVC pipe, bevel off the top and bottom pipe edges with a 1 inch tabletop sander, drill and countersink holes for the screws, drill pilot holes in the chair frames, seat the self-tapping screws through the PVC pipe and into frames.
Elapsed time to do five chairs, one hour with a beer break. dang that was easy.

Eh, that is only four chairs. Daddy got a new sunbrella for his birthday.
53 inch canopy. BTW, umbrella specs can be misleading; they commonly list the measurement across the top of the canopy, in this case 68 inches. But the open diameter is actually 53 inches, still plenty big enough for personal shade.
Opaque UVA/UVB reflective material, graphite shaft, double canopy with vents for heat and wind escape.
Handle cut off (and, yeah, saved for who knows what, maybe the next time a porcupine eats a fishing rod handle).

Pad eye pop riveted on for bungee tie down attachment.

A little custom length bungee ball work.

Schweet! That is a lot of back and overhead sun coverage and, umbrella porn three-poles-in-holes, still takes only seconds to set up.

Yeah, yeah, it is the freaking Inspector Gadget Chair. Now get your sunburned neck and thighs outa my seat.
