Looks like the 7-piece Bottomsiders set is $200 more than the "SunSure" set. I routinely pull the ones I have now (not sure what type they are...but pretty sure they are not BottomSiders) off and stow them down below. So stowing them is not a big issue for me.
I checked with a canvas/cushion guy in the local area about recovering what I got. His estimate was $50 per foot as a "ball park" figure. So this was probably going to be a $600+ job and that was for "single piping". And would be cushion less for 2-3 weeks probably.
Just more to think about.
Cheers,
Jim
