Chad,
I voted Swivel because I have two that do swivel. One is a hard plastic stool that adjusts height with a round seat and a cushion that is Velcro to hold it on.
After an hour I hated it but did use it cause it swiveled but noisy.
A few years later I was sending p.ms back and forth to Mike Mitten and he told me how much his Dad liked the Huntmore 360 and it was comfortable as well .
That p.m. we shared made up my mind to try one so my wife bought me one for my birthday about 7 years ago I believe.
I know many folks "Have" complained about the cost,the weight,and where it was made and I just want to say opinions were many.
I noticed a small squeak in mine and Scott Hoffman was kind and quick to send me a new set of washers,Bigger wing nuts with a bigger handle,new back support and quick detach seat clips.
He explained in detail how to maintain the seat and lube it each year. I have enjoyed the swivel so much that I can slowly turn or move it without a squeak and sit for a day with a little break if need be.
Now since Scott has closed the business down and I don't think anyone is still making them I thought what would be the perfect seat that is Light weight,quick to set up, built like a tank, made to last for years and affordable?
I would try another brand JUST to compare to my Huntmore if it was compatible to the Huntmore.
Do you have an idea up your sleeve Chad ?
