Helinox Cot One Leg Extensions (12 pcs)
- Best for:
- Owners of Helinox Cot One Convertible (and compatible convertibles) who want chair/bench height (~15 in) for easier in/out, under‑cot storage, and greater comfort at car camping, basecamp, overlanding, motorcycle camping or longer stays where weight isn’t the top priority.
- Skip it if you want:
- Ultralight backpacking/fastpacking or any situation where saving ounces and managing many small parts matters; not ideal for very tight/tiny tents due to fiddly installation.
Main tradeoff: Significant weight penalty for an accessory (kit packs to ~510 g / ~18 oz).

Details
About the Helinox Cot One Leg Extensions (12 pcs)
A 12-piece leg extension kit that snaps onto the existing leg hubs of the Helinox Cot One Convertible or Cot One Convertible L, raising the cot to a 15in high-cot height. That extra clearance makes it easier to get in and out of a sleeping bag and frees up space underneath for gear storage. The legs pack into their own cinch bag and use the same green anodized DAC aluminum alloy as the cot.

Questions (5)
- How much weight does the 12‑piece kit add?
- Pack weight is about 510 g (≈18 oz) with the carry case (the kit is roughly 1.0–1.1 lb), so it’s a nontrivial addition and not suitable for ultralight backpacking.
- Will the legs fit my older Cot One (V1/V2)?
- Compatibility warning: Helinox Korea and other regional notes indicate the 12‑piece kit may not be compatible with some older Cot One V1/V2 models without exchange/modification—check Helinox compatibility notes before buying.
- Will the legs damage my tent floor?
- Potentially yes—multiple reviewers and users warn the small feet can abrade or puncture thin tent floors or footprints; use protective pads, chair tips, or a groundsheet under contact points.
- What’s included in the box?
- A 12‑piece leg set and a small cinch carry bag; mont‑bell and Helinox instruction pages indicate you should receive and install all 12 legs for the conversion.
- How long will the kit last and what about warranty?
- There’s limited high‑volume long‑term data specific to the leg kit; Helinox lists a 5‑year warranty for manufacturing defects—inspect parts on arrival and inventory all legs before a trip.
Weather and conditions

What tends to wear out

- missing parts at delivery (reported cases of missing legs)
Durability
