At this time we do not have a kit for purchase to make your Vibe Hero seat higher. Be aware that changing the height of the seat will affect the stability of your kayak.
Be mindful, too, that DIY options may compromise the integrity of your kayak and/or Hero seat and Vibe takes no responsibility nor liability for any damage if you do use DIY options.
If you do choose to tackle DIY, we have a very talented group of DIYers in our Vibe Facebook Owners Group that can give you tips. Check it out here!
