These chairs make all the difference! They are so easy to attach to the boat - no awkward clips and easy to change position for different paddlers in seconds.
They do make the kayak a little less stable initially (as Rishard advised me on the phone), but after a few minutes you get used to different feel of the boat and they are perfect. We've only paddled about 10 miles in them so far, but wont go back to the standard seats for long trips.
Another great purchase from this company - If you have this boat - what are you waiting for!?!?!
