leather seats

Has anyone who has leather seats had them crack horizontally on the sides? I was wondering if there was a "leather repair kit" or something that could be used. Mine has a crack about 2 inches long just above the handle on the driver's side to tilt the seat back.

Autozone has a repair kit.
The thread on my drivers seat on top by headrest is going to have to be fixed soon. Not gone yet, but soon.

Thank you sir.
