The purpose of this article is to review the Helinox Chair Zero to the REI Flexlite Air Chair and see if there are any meaningful differences.

The Helinox Chair Zero is probably the most beloved lightweight camping chair among hikers who pay attention to the weight of their kit.

The reason for this is that when it was introduced, it was the lightest “real” chair on the market. At just over a pound, it still offered all of the benefits and features of a comfortable chair, including an off-the-ground seat, a suspended seat that cradled your back and hips, a supportive backrest, and enough height so that your feet settled on the ground well below your hips.

Biomechanically, these are the key ingredients to relieving strain from the musculoskeletal system in a way that promotes, rather than hinders, restful recovery after hiking all day. (Chairs for backpacking should be designed with similar features as chairs for long-distance driving, with the goal of reducing biomechanical stress; unlike office chairs, where the goal is to foster a healthy posture with core activation).

While a backpacking chair isn’t commonly carried by thru-hikers or fastpackers who spend little time “camping” on their hikes, it’s becoming less and less of a luxury item now that chair weights are decreasing, and more options hit the market.

The REI Flexlite Air Chair is new for 2019. It’s made with lighter materials and is a slightly more compact design than the original REI Flexlite Chair. The latter chair weighs 12 oz more than the Flexlite Air, and is a little more stable under heavier loads.

The following video review presents a quick whiteboard class on chair design and compares the Helinox Chair Zero to the REI Flexlite Air Chair.

Performance Notes

Weight Capacity:

  • No discernible differences could be observed between the stability of the two chairs when I sat in each one with 75 pounds of barbell plates in my lap and I wobbled around. Both chairs offered a terrible experience! I weigh 165 lb, and without artificial weight in my lap, found them both to be stable enough while sitting on firm soil.

Leg Angle:

  • Leg angles were measured by extending feet forward until the front edge of the seat fabric starting digging into my hamstring.
  • The lower leg angle of the Helinox Chair Zero makes it more comfortable to extend your legs forward (i.e., less knee bend) without the front edge of the seat digging into your hamstring. This is more comfortable for some. However…
  • The higher leg angle of the REI Flexlite Air Chair combined with its deeper seat cradle your hips and body more comfortable, while in a normal sitting position with legs folded near the chair.

Back Height:

  • The higher back height of the Helinox Chair Zero provides enough noticeable increase in fabric to increase comfort notably, regardless of your height (but especially for taller sitters). The back fabric edge may dig into your back when you lean far backward, and that may be disconcerting to some.

Folded Size:

  • The more compact folded size of the Helinox Chair Zero is primarily an issue only when comparing the paper specs provided by the manufacturers of these two chairs. Actual measured dimensions are much closer, and both chairs fit sideways into most of the larger (55+ L) backpacks I tried.

Final Commentary & Recommendations

I recommend both of these chairs. They are well-constructed, durable, and the lightest of their kind on the market.

To save additional weight, you have to give up four-leg stability and/or ground clearance (e.g., the Alite Mayfly), use a chair without a supportive, cradling seat (e.g., the Trail Chair), use a chair without a supportive backrest (e.g., a bear canister or stool), or just sit on a little piece of foam (which really only serves to keep your butt dry and clean, offer no biomechanical advantages whatsoever).

My current chair of choice is the REI Flexlite Air Chair. It’s slightly lighter than the Helinox. I find the Helinox to be marginally more comfortable, but not worth the extra 1.9 oz for me!

Dream Chair?

This type of design – four legs, off-the-ground seat, and a backrest – should be the gold standard for backpacking chair comfort. However, there is an opportunity for improvement, weight savings, and innovation. Expectedly, these advances would come from the cottage community rather than mass-market manufacturers such as REI or Helinox:

  1. Lighter weight and more stability (less wobble) can be accomplished by using carbon fiber tubing. Thick-walled tubing and outer ferrules may have to be used to resist breakage.
  2. Lighter weight and less water absorption (faster dry time) can be accomplished by using fabric such as the 1.0-oz Dyneema Composite Fabric used in tent floors (e.g., Tarptent, ZPacks, Hyperlite Mountain Gear).
  3. Perhaps there is some market opportunity by using lighter weight materials with a lower weight rating.
  4. And how about some type of chair kit that mates with trekking poles to create a four-legged, off-the-ground chair with a nice seat and backrest?
