Seated buggy board for Quinny Zapp?

[Hangingbellyofbabylon]

I'm looking for a buggy board with a seat for my zapp, I know they are massive and bulky but dd is disabled and wouldn't always have the stamina to stand on a normal buggy board. I have been told that the 'Litaf pick up seat' doesn't fit. Does anyone know of any others that fit the zapp? thanks.

i would think it would be REALLY hard to push with one of those on it,as you will have to really hunch over it,
my sister had the litaf one and it was huge,her pram was great for it (big britax classis thingy) but she still had to hunch over it,
