I've got a row of 090 recliners, but wish I could have fit more chairs in the same width. The 090s are WIDE.
My only gripe with the 088s is that the arm rest are too narrow. I like the narrower seat, but the row I sat in at a local JC Penny's made be feel like I'd be fighting for the arm rests with my neighbor. Those were not the wedges, though, so perhaps a curved arc would be better.
What I want is a hybrid. If I had to chose one or the other, given my space limitations, I'd go with the 088. Wish they had been available a couple of years ago.
In any case, my 090s are very stable, sitting on carpet, and the ability to shove them (takes some effort) aside aids in cleaning.
