A lumpy rock, cold hard stadium bench, old bus seats without cushioning, none of these sound like a comfortable place to park your bum. Unless you have the Sea to Summit S.I. Seat!
This little guy is basically a miniature self-inflating mattress, only much smaller. It rolls up nice and small, and when you need to turn an uncomfortable surface into a padded and insulated place to sit, all you need to do is pull this handy seat out of its carry case, let it self-inflate and place it under your buttocks.
Great for hiking, trekking as well as for sporting events and picnics, the S.I. Seat is a welcome lightweight addition to the gear you are taking on any adventure.
Foam filled for comfort and insulation
Patented mini-valve for easy inflation and deflation
Valve allows for fine tuning of comfort

R Value1 answer
What is the R Value of the seat, please?

The S.I. Seat hasn't been tested for R-value, as this measurement has specific testing requirements, specifically to sleeping mats. At a guess based on similar mats, we'd take a guess at it being around an R-value of 3.

Would this cushion be suitable for use in a kayak where it will most likely get wet?
Yvonne - Brisbane, QLD(2 years ago)
It wouldn't be ideal to get this seat pad wet. I would recommend something like the Thermarest Z-seat, or the Exped Sit Pad, which would be waterproof whilst adding extra padding and comfort.

Do you think this cushion will work on a camp chair1 answer
We live on the road and my bum will often get numb if I sit too long on my camp chair. My camp chair had a lot of structure but I am concerned about the cushion moving around a lot.

Yes, this Seat Cushion should work on most camp chairs, it will add some padding, and shouldn't move around too much (obviously depending on the fabric of your chair).
