Jackson Sweet Cheeks are like beanbags for your kayak seat. By inflating the bag you can move the "beans" around to make your kayak seat more comfortable, then use the suction tube to remove excess air from the bag and the "beans" will stay where you want them. It's like a custom fitted seat bottom. Most Jackson river kayaks come with Sweet Cheeks, and they can be added to other kayaks if your kayak has enough room as these will raise you up a bit; sometimes raising yourself up in the seat makes a boat fit better too.

Sweet Cheeks come in two thicknesses:

Sweet Cheeks 100 (comfort with minimal thickness)

Sweet Cheeks 200 (thicker for more seat height adjustment)
