Helinox Chair Zero vs REI Co-op Flexlite Air (2026)
Two sub-20-ounce backpacking chairs. Official Helinox numbers are exact; Flexlite Air figures come from dated third-party tests because REI.com blocked our fetch.

Quick answer
Choose Helinox Chair Zero ($139.95) if you want official Helinox specs and a 5-year warranty or a $139.95 official price and possible stock waits are acceptable. Choose REI Co-op Flexlite Air ($100) if you want the lower $100 list price cited in 2025–2026 reviews or saving a couple of ounces versus the packed Chair Zero matters.

We compared these chairs using Helinox’s official Chair Zero page (fetched November 10, 2026), OutdoorGearLab’s Flexlite Air review and backpacking-chairs roundup (both updated September 28, 2026), and CleverHiker’s Flexlite Air review (August 28, 2025). Attempts to fetch REI.com product pages returned HTTP 403, so official REI copy and a live REI price are not quoted. We haven’t sat in these chairs, and we don’t give scores.
Choose the Helinox Chair Zero if you want official specs we could fetch: $139.95 (sold out on November 10, 2026), 1 lb 2 oz / 509 g assembled or 1 lb 2.5 oz / 531 g packed, 265 lb capacity, 14 × 4 × 4 in packed, 6.5 in seat height, and a 5-year warranty. Choose the Flexlite Air if weight and a lower list price matter more: OutdoorGearLab’s September 28, 2026 review lists $100, 16.9 oz on their scale, a 250 lb maker capacity, and about 7 in of seat height, with notes that stability is poor and setup is easy. CleverHiker’s August 28, 2025 Flexlite review also lists $100, 1 lb and 250 lb, but prints an 11 in seat height — we report both seat-height figures rather than picking one. We could not fetch REI.com (HTTP 403), so we do not invent a current REI shelf price.

What are the pros and cons?
Helinox Chair Zero: pros
- Official packed weight just over a pound, with a 265 lb capacity and a 5-year warranty
- Official 14 × 4 × 4 in packed size and 6.5 in seat height are documented on the maker page
- CleverHiker’s Flexlite review (August 28, 2025) said the Chair Zero felt slightly more comfortable and stable, at about 2 oz heavier and a higher price
Helinox Chair Zero: cons
- $139.95 official, and the official page was sold out on November 10, 2026
- A 6.5 in official seat height is low to the ground
- OutdoorGearLab’s backpacking-chairs roundup discusses a Chair Zero LT that broke at the 265 lb limit — that is a different SKU than the Chair Zero we cite here
REI Co-op Flexlite Air: pros
- Lower list price in the reviews we fetched ($100)
- OGL’s September 28, 2026 review lists 16.9 oz and easy setup, and the chairs roundup includes it among the lightest full chairs
- 250 lb maker capacity is still in backpacking-chair range
REI Co-op Flexlite Air: cons
- OGL’s review calls stability poor
- Seat height is reported as about 7 in (OGL) and 11 in (CleverHiker); we cannot resolve that without an official REI page
- We could not fetch REI.com, so we do not confirm today’s shelf price or official packed dimensions
Which should you choose: Helinox Chair Zero or REI Co-op Flexlite Air?
On official numbers, the Chair Zero is a documented one-pound-class chair with a 265 lb capacity, a 6.5 in seat and a 5-year warranty, at $139.95 and often out of stock. The Flexlite Air is the cheaper, slightly lighter option in the reviews we could fetch, with a 250 lb maker rating and a stability caveat from OutdoorGearLab, plus a seat-height disagreement we will not paper over. We have not sat in either chair, and we could not open REI.com. If you need a chair that sits higher off the ground, confirm current Flexlite geometry on a page you can read, or look at a different chair than these two low seats.
Choose Helinox Chair Zero if…
- You want official Helinox specs and a 5-year warranty
- A $139.95 official price and possible stock waits are acceptable
- A 6.5 in official seat height is low enough for your camp style
Choose REI Co-op Flexlite Air if…
- You want the lower $100 list price cited in 2025–2026 reviews
- Saving a couple of ounces versus the packed Chair Zero matters
- You will confirm today’s REI price and geometry yourself, because we could not fetch REI.com
The Flexlite Air seat-height disagreement
OutdoorGearLab’s September 28, 2026 Flexlite Air review describes a seat height of about 7 inches. CleverHiker’s August 28, 2025 review of the same chair lists 11 inches. Those cannot both be right for the same geometry, and we did not get an official REI spec sheet (HTTP 403). We report both figures. Helinox’s official Chair Zero seat height is 6.5 inches, which is in the same very-low range as OGL’s Flexlite number, not CleverHiker’s 11-inch figure.
Who should skip both?
- People who want a high camp chair or a rocking chair. These are low backpacking chairs.
- Users over the maker capacities (265 lb official Helinox; 250 lb maker rating on the Flexlite as cited by reviewers).
- Anyone confusing the Chair Zero with the Chair Zero LT. OGL discussed a Zero LT that failed at the 265 lb limit; that is not the Chair Zero official page we fetched.
