The Therm-a-Rest Treo is camping chic on top of being portable, as it folds down into its base stand. This didn't, however, prevent it from scoring at the bottom of the heap compared to the other models we reviewed. Therm-a-Rest markets this chair as "Big comfort in a small package." Unfortunately, we think it might be more accurately described as, "very packable, moderately comfortable, but not very useful." The Treo is so unstable that it really decreases its function. Uneven or sandy terrain will pitch you right out of this bucket seat. Try reaching for something just out of arm's reach and you might regret it (one tester did…). It is lightweight and small, but not convenient enough for us to recommend it, even as a portable chair.
A new iteration of the Treo is out and pictured above. The updated version features some mechanical design changes to the original design, which we detail below.
