It's pretty obvious in a tree stand but I hunt from a popup blind for bow season and a box blind for gun season. I've used everything from a bucket to an office chair to bag chairs to folding chairs.... each has its pros and cons.

What have you found that works best for you in either a box blind or popup blind?

I use a simple folding chair with no arms so I can draw corner to corner in the pop blind while bow hunting if I'm on the ground. The gun blind I have a nice cushy office style chair.

no squeak folding chair
and boat cushion

for bow? those backless chairs with the triangular seats are the best, but it sure sucks for a long sit. Last year I took a regular fold up blind chair (the ones that slide into a tube-bag), cut the back off and cut the right back support off as well as the right arm rest and support. I could still use the left back support for, well, back support, and the left armrest for my spit cup. Still not as easy to shoot from as the triangle stool, but it was a compromise of comfort and shootability.

the third row seat out of a lincoln navigator lol my friend totaled his so i took the back seat and built some support legs and set it up its even got seat belts hahahah but really its comfy

Something that swivels.

a boat cushion (or two)lets you
sit up higher and transition
up and out of the seat easier
and quieter if you need to or
just lets you sit higher for
a sitting shot or whatever
presents itself

I use the plastic resin chairs in my deer stands. No squeaking or metal banging noises. Light to move around, back rest and arm rest. Kind of comfortable.

Something with a back but the less of a slouch has worked best for me! But there's nothing like the recliner after you get out of the stand

Pop-up blind is a lawn chair w/ cupholders.... Box blind is tall back, reclining office chair with arms.

Had cheap folding chair at the old lease in a box blind. Also had an old metal office chair in a pop-up. New lease have two swiveling office chairs in the double box blind, that metal office chair in the single box blind.

those are nicer than what i use,
but when i try to use one, they
are possessed by the spirit of
murphy. . .

squeeeeeeeeek ! ! ! ! !

(that only happens when i spot something-
you can't get it to squeek otherwise if
you threw it out the back of a truck
on the interstate)

big ol' executive office chair is the only way to go!

office chairs

Same.

What if you aren't hunting from a blind....just a cushion on the ground or does anyone carry a chair or bucket out there every day?

Office chair.

I like the office chair for me in the double blind but a bag chair or folding chair for the kids since I can fold it up when hunting alone or when they want to lay down for a nap on the floor.

Good answers though...keep them coming.

In my 6x8 box blind I use a lazy boy recliner.

A small foldable swivel chair with no arms when hunting in a ground blind. I don't hunt out of nice box/tower blinds. I like being close enough to smell their breath.

My badonkadonk.

Padded boat seat with swivel mounted on a 5 gallon bucket.

I've recently added a new base instead of bucket for shorter shooters. Pipe that slides inside the other and 2 big set screws to set it at what ever height I need. I battled all last year getting a chair to put my then 9 year old son at the right height to make a comfortable shot.
