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.

R Value1 answer
What is the R Value of the seat, please?
Stephan - West Footscray, VIC(9 months ago)
G'day Stephan,
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.

Waterproof?1 answer
Would this cushion be suitable for use in a kayak where it will most likely get wet?
Yvonne - Brisbane, QLD(2 years ago)
G'day Yvonne,
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.
Wenda - On the roaf(3 years ago)
G'day Wenda,
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).
