Kaiser 4 XL

Anda seat sits hot, I had the original kaiser and I absolutely hated it like ended up getting rid of it after a few months hated it. My wife loves her secret labs I think it's eh so so. Personally I wouldn't give up my X chair for anything but they are hella pricey.

so got secretlab flush armrests and they fit fine as size is almost same for kaiser 3 L - however there is need to adjust place where button is as those are different, secretlab (small round) and andaseat (bigger triangle) - so some time with grinder is needed...(btw those side buttons are removable
