Dometic TRT 140 AIR vs Naturnest Andromeda

The Dometic TRT 140 AIR and the Naturnest Andromeda are both softshell tents in the same part of the market, which makes them a genuine head-to-head rather than a comparison across categories. Dometic and Naturnest take noticeably different approaches to the same problem.

On weight they are effectively level — 47 kg against 49.38 kg — so the roof load question resolves the same way for both. Floor area is close to identical at 3.16 m² and 3.22 m², so neither wins on sleeping room. The Andromeda lists $1,571 lower, at $929 against $2,500.

They open differently: the TRT 140 AIR is an inflatable and the Andromeda a fold-out. That is not cosmetic — it decides whether headroom is even across the tent or tapers towards one end, and how much of the roof the tent occupies when closed. Canvas differs too: 300D ripstop polyester against polyester canopy with 620D mesh.

Dometic

TRT 140 AIR

The only inflatable tent in this database. A single-point AIR frame replaces poles entirely, which is how it reaches 47 kg and why it packs to 82 cm wide — narrow enough for hatchback crossbars that most rooftop tents overhang.

  • 47 kg, and no poles to bend or snap
  • 82 cm closed width fits small car racks
  • No poles to break or bend
  • 3.2 cm mattress is thin

Naturnest

Andromeda

The Andromeda is Naturnest's soft-shell fold-out tent (Dark Green), rated for two to three people at $929. Its published open size is 140 x 230 x 110 cm, folding to 145 x 117 x 35 cm, with a 2.5 cm foam mattress, a 620D-mesh polyester canopy under a removable PVC cover, a 360-degree skylight, ten windows and two doors, and a W/R 5000 waterproof rating.

  • Lower priced than Naturnest's hard-shell models
  • 360-degree skylight with ten windows and two doors
  • Removable PVC travel cover
  • Published weight figures are inconsistent between listings

Which one to pick

Take the Andromeda if the budget is fixed. Beyond that the feature rows below — heater port, skylight, annex, cargo rails — are where the remaining difference lies.
