I second the office chair, its all I use in my blinds, they are quiet, adjust for height, and SUPER comfortable , can sleep in them LOL

having wheels on them can also help with getting into odd positions easier too!

I have found a LOT of them in classified adds used for about 15-20 bucks too!

I oil mine before the season and before off season, to keep them squeak free too!

highly recommend them!
