Have a look at the thermarest chair kit, looks like a similar design
Thanks @benp1 . Yes, I've seen the Thermarest version but it's quite heavy. Curious to learn (steal!) ideas from @Clare .
Still using my Jerry-Chair,
doubles as ground cloth/welcome mat under my hammock, or as a pack cover.
I'm planning a replacement that will double as a rain kilt.
Last years chair: I used parachute nylon, not very sturdy webbing for retaining sleeves, 4mm carbon rods in the retaining sleeves joined at the hinge point by plastic air tube (for fish tanks). Elastic bias binding on the edges of the “pockets”.
The angled straps were made of 4mm grosgrain ribbon and 3mm cord with a line loc. The ribbon threaded through a button hole in the webbing sleeve so that the ribbon looped around the back of the carbon rod at each of the four connecting points. This method meant that the tension of the angled straps pulled directly against the carbon rods and I didn’t need to construct a strong fabric structure that could bear the tension. This is where my design was more structurally efficient than Therm-a-Rest I can’t remember why I didn’t just thread the 3mm cord through the button hole/around the rod but I think it’s because I couldn’t thread the cord through an upholstery needle - too thick. So the ribbon joined to cord was a bit clumsy and that’s where it broke.
If I did it again I would use 90 gsm nylon, 10mm carbon tubes, wider air tube for the bigger carbon tubes, stronger webbing channels, and instead of cord + lineloc i would use 10mm webbing and a buckle to connect the straps coming from top to the one coming from bottom (as in the trekker chair). I wouldn’t faff around with upholstery needles but would cut a 10mm hole in the webbing at the 4 connection points, lay the 10mm gross grain over it and then insert the carbon pole into the webbing channel making sure that the ribbon was behind the pole as it passed through, so that it would effectively be looped around the pole.
If that doesn’t make sense I can post pics of details of the chair. It’s still here.
Thanks @Clare , that's very detailed.
I did see the post of your previous chair so I will take a look at those pics and try to understand your improvement suggestions.
This thing is about 150g and works really well once you get the hang of it. Stable and solid. I plan a dual use version with a cf layer glued to a 2mm foam sheet (to be also used as sit mat and under SDS sleepmat) but finding the time is a problem...
Bed bath could be another use
Here is a video of a new ASTA UL Gear folding stool. Can't say I checked the weight...
Are you going into production Clare?
Too small to be of real use..(IMHO) . That's why my vango is worth it's extra weight... It give a sensible spread and height.
I cart a Vango Skye Tall stool around. Usually for sitting on when cooking and such but I cut a big hole in the seat and I can put a biodegradable bag in it to turn it into a (fairly) comfy loo.
At my age 400g is well justified in my opinion.
The Aldi ones were down to £12 - I had three of them for that price. I was in Cotswold Outdoor yesterday, they’re knocking out the Robens ones for about £60 / £70 and theta 100g heavier.
I've seen lots of those on Amazon, the positive reviews all use the same photos....
Can’t see a weight for that stool. This might be lighter ?

Weights seem to be a little under 400g, tempted to give one a go for camping with the kids.
The ones you linked to are interesting, but look for kids?
Picked this up from a nice chap recently,hope to get out this wknd if the weather settles back down from this heat
@Munro277 be interested to see what you make of it. The reviews say there is much faffing around to get set up as you sit. It might be too much bother.
Tried it a few times now in back garden and I’ve found it much comfier than it should, if it cools at wknd and I get out it’s coming with me.
