Therm-a-Rest Trekker Chair Review

Overview

The Trekker Chair isn’t a chair at all — it’s a fabric sleeve with fiberglass stays that wraps around your existing inflatable sleeping pad and turns it into a low camp chair. It’s aimed at backpackers who already carry a NeoAir or self-inflating pad and want back support at camp without adding a dedicated folding chair to their pack. If you’re the type who’d rather repurpose gear you’re already carrying than buy a single-use item, this is the category the Trekker Chair is built for.

Performance

Setup is genuinely quick once you understand what you’re working with. You inflate your pad first, then slide it into the sleeve — a reviewer on Trailspace noted they could set it up in under a minute once the sleeping pad is inflated, and don’t find it that difficult to insert the pad into although not using a doubled-over 2-inch pad as it is designed. Breaking camp is just as fast: deflate the mattress, slip the chair off, and roll it up.

The elastic sleeve edges are the key engineering trick here — the elastic sleeve edges stretch to fit both NeoAir and self-inflating pads, so you’re not locked into one specific pad model. That said, a chunk of the confusion I found in reviews and forum threads traces back to first-time buyers not realizing what they’re purchasing. One buyer put it bluntly: I thought it was a chair. It is really a cover that you use a pad to create a chair with. If you don’t already own a compatible pad, this thing does nothing for you.

Comfort-wise, the design leans on your pad doing double duty as both cushion and backrest — the pad makes a tall back for support and a double thick seat for cushioning, and unlike stretched-fabric camp chairs, this chair is nice and warm on the backside since you’re sitting on an insulated pad rather than bare nylon. The backrest angle is adjustable via side straps, which matters more than it sounds — you can dial in a more reclined lounge position or a more upright “cooking dinner” angle.

There are real limitations. It’s a ground-level seat with no legs, so as one long-term Trailspace reviewer noted, it could be a bit taller in the back, and is usable but not overly comfortable on its own without a pad. Sitting on the ground also means dirt and moisture are an issue: as it’s a seat on the ground, it fits well for lounging around in your shelter but would get dirty sitting around camp and takes a little while to dry out. If you want elevation off the ground, you’re improvising — one reviewer said he’d prefer to sit up off of the ground a bit so I usually look for a big log or large flat rock and use those things for some chair legs.

Durability seems fine on the shell itself — no reports of the fiberglass stays snapping or the fabric tearing under normal use — but the design does put your only sleeping pad at risk. Since the chair only works because your pad is inside it, use some care when picking out a spot to sit because a sharp briar or hot em[ber] could mean a puncture that costs you your night’s sleep, not just your afternoon seat. That’s the trade-off with this whole category of “dual-purpose” pad accessories: you’re borrowing risk from your sleep system to save chair weight.

On the actual number: retailers list it as 290 g / 10 oz for the 20-inch version, though at least one long-term owner found their unit read differently on a home scale — Therm-a-rest specs state that the Trekker is 9.5 ounces, but my scale says just a hair over 10 ounces, so there may be a difference between the old version and the current one. Not a big deal either way, but worth knowing the spec sheet and your kitchen scale might not agree exactly.

Pros & Cons

Pros

• Genuinely light for what it adds — 290 g is far less than any freestanding packable camp chair
• Packs down to a slim roll (10 x 51 cm) that disappears into a side pocket
• Elastic sleeves accommodate both NeoAir and self-inflating pads, so it’s not locked to one pad model
• Warm to sit on since your pad’s insulation comes along for the ride
• Adjustable backrest strap lets you tune the recline angle
• Quick to set up and break down — well under a minute either way

Cons

• Doesn’t work at all without a compatible pad you’re already carrying — it’s an accessory, not a standalone chair
• Ground-level seat height; no way to get elevation without improvising with a log or rock
• Puts your sleeping pad at risk of punctures while you’re using it as a chair
• Gets dirty on damp or dusty ground and takes time to dry before you can pack it away
• Genuinely confusing at first glance for buyers who don’t read the fine print — expect a return if you buy on impulse

Who Should Buy This

This is a smart buy for pad owners who already value comfort at camp — thru-hikers and long-trail backpackers who spend real evening hours sitting around rather than crawling straight into the tent. It makes the most sense if you’re using a NeoAir or a compatible self-inflating pad already, since the whole value proposition evaporates if you have to buy a new pad just to use the chair. If you want a chair that stands alone, works on any surface, and doesn’t touch your sleep system, look at a dedicated packable stool or a hammock-style chair instead — you’ll pay more in weight but get more separation from risk.

Verdict

The Trekker Chair does exactly one thing well: it turns a pad you’re already carrying into a genuinely comfortable, warm seat for around 10 ounces, which is hard to beat on a weight basis. The catches — ground-level height, pad puncture risk, and the fact it’s useless without a compatible pad — are real but manageable if you go in with clear expectations. I’d rate it a 7/10: excellent value and weight efficiency for the right user, docked for the ground-clearance limitation and the learning curve around what it actually is.
