Update: I removed a negative, there IS a set of alignment lines on each section. These lines weren't mentioned in any written materials but are clearly visible on each section.
After travelling a lot before COVID19 hit, I purchased a folding cane/seat while in the UK that has been a back saver dozens of times. Now, this improved version of the Sitpack kickstarter has it beat! If you are considering this, get the case that turns into a cushion! The kit here includes the case and an extra two "feet" that do wear out over time.
This Sitpack 2.0 folds smaller than any competitor and with the carrying case used as padding fits my buns just like my ergo bike seat! The Sitpack Zen with its sling seat may fit better for some people - I prefer the easily repositioned feel of the Sitpack 2.0. A feature of both this seat and the ergo bike seat is the need to readjust your buns just a bit from time to time. For me this increases the comfort of the seat!
Here are my usual pros and cons, first the pros:
+ Folds into a package about the size of a 20 ounce/0.5L soda can
+ the carrying case/cushion fits well and stays put, along with helping your buns do the same
+ the "foot" is great on any hard surface, even irregular stone surfaces
+ the strap with the case is essential if you aren't carrying a backpack or other case to stow the Sitpack
Cons:
- really wish there were another type of "foot" that worked better on rugs and other soft flooring
- for many who have tried this seat, especially those with wider buns than mine, the surface is too small for comfort; a padding option that provides more of a seat surface could fix this
- had to use two Velcro straps to hold the seat/case on when in the open position
Can't believe such a comfortable seating option comes in such a small package. Get the Sitpack 2.0 WITH the carrying case and you'll see what I mean!
