Aren't Kirkleys those aluminim rally seats? I'm sure someone has mentioned them before.
I'd do a search for them as I remember a post about that not so long ago!
As for me, I got these babies from J K Composites
They're lightweight and comfy
SWMBO has categorically stated that even if her hips did fit, she wouldn't be seen dead in the buggy!
The seats are really skinny, 38cm gap for the hips, I'm not a lightweight and just fit, they're definitely what you call snug!!
Yes... snug. Luckily i am of lanky thin physique so fit in mine a treat. But offroad it would hurt in them, so im going to cut up a camping mat and mount the seat on rubber bobbins.

I bought 2 of these for my buggy, I went for the 20 degree layback economy seat 17 inches wide with covers from bpgrassing.
They are a little snug on the central tunnel, so I would recommend a narrower size .
