I'm also a little north of 250 and hated the bag chairs, They were comfortable but a pain to get out of. I tried a few director chairs and they where easy to get out of but not as comfortable as the bag chairs. (My opinion)
I read a few online reviews that rated the Kijaro chairs very highly. I went to Dicks Sporting and tried the Kijaro XXL Dual Lock Oversized Chair. They fit my need for comfort and ease of use. And they were $39.99 (plus my 20% coupon).
