I made a homebrew copy of the strap chair and it works for short periods but I quickly stiffened due to lack of mobility.
I bought a Helinox ground chair (don’t fit into the others) but its never left the house.
Here are a couple left field suggestions that work best for me.
If I know I’ll spend at least a few hours in camp, I love this over a chair:
- Coghlan’s hammock, $32Can, 7.5oz with 2×6′ poly rope.
- I’ll usually also carry one Kamoch Python UL10 10″ tree strap, 1.6oz.
The hammock takes the weight off my back, butt and legs and really helps with muscle recovery. Set up is no slower than a chair and its much more comfortable.  I’m surprised more don’t use it.  Kinda stinks above treeline though!
If you have access to Decathlon, the Forclaz sit pad is also good and cheap ($10Can, 1.8oz). I’ll usually take one to use when its wet or on breaks.
I’ll swap that out for a Klymit V-seat (2.3oz) in winter (warmer) or to double as stiffener in my Osprey Ultralight stuff sack (3.9oz) which I’ll take on my fishing backpacking trips where I set up a different base camp each day & then go lake hopping. Less convenient but definitely cushier than a foam seat pad and packs much smaller, if you don’t mind a breath to inflate it.
