The short answer: sleeping upright versus lying down
These two do different jobs: the Cabeau Evolution S3 is a neck pillow built for sleeping upright in a seat, while the Therm-a-Rest Compressible Pillow is not a neck pillow at all but a rectangular camp pillow stuffed with foam offcuts, built for lying down. For planes, buses and car passenger seats, buy the Cabeau, because it holds your head in place and straps to the headrest. Buy the Therm-a-Rest if your trip involves lying down, such as sleeper trains, lie-flat seats, hostels, camping or hotel beds with thin pillows, or if you like to wedge a soft pillow against the window. Therm-a-Rest's own store now sells it as the Compressible Pillow Cinch, which adds a cord to adjust firmness and cinch it down for packing.
Key differences
| Cabeau Evolution S3 | Therm-a-Rest Compressible Pillow Cinch | |
|---|---|---|
| What it is | Travel neck pillow: U-shaped memory foam with raised sides and a flat back | Rectangular camp and travel pillow: upcycled urethane foam pieces with a soft synthetic top layer |
| Best position | Sitting upright in a seat | Lying down, or propped against a window or wall; OutdoorGearLab found it better for back and stomach sleepers than side sleepers |
| Holds your head | Yes: front clasp, raised sides and a strap that attaches to the seat | No; it is a loose pillow, and OutdoorGearLab found it loses some height as the foam compresses |
| Sizes | One size | Small 15 x 11 x 5 in, Regular 18 x 13 x 6 in, Large 22 x 15 x 7 in (Cinch version) |
| Weight | About 11.6 oz (Sleep Advisor) | 8 oz, 11.5 oz or 16 oz depending on size (manufacturer) |
| Packing | Compression case shrinks it to about one-third size, with a luggage clip | Stuffs and cinches into itself; OutdoorGearLab measured about 2.6 liters packed |
| Adjustment | Front clasp adjusts the fit around the neck | Cinch cord adds loft and firmness |
| Price (Sept 2026) | $39.99 at Cabeau | $34.95 in any size at Therm-a-Rest |
Choose Cabeau Evolution S3 if…
- you mostly need to sleep sitting up on planes, buses or in a car's passenger seat.
- your head tends to fall forward or sideways; the seat strap and raised sides exist to stop that.
- you often sit in a middle or aisle seat with no wall to lean on.
Choose Therm-a-Rest Compressible Pillow Cinch if…
- you will be lying down: sleeper trains, ferries, hostels, lie-flat seats or hotel beds with flat pillows.
- the same pillow also needs to cover camping or car camping.
- you usually take the window seat and would rather wedge a soft pillow against the wall than wear one.
Pros
- +Raised side supports prevent head bobbing
- +Flat rear profile works with headrests
- +Seat strap keeps pillow attached to seat
Cons
- −Bulky to pack despite compression bag
- −Gets warm during long use
Don't buy if
- ⚠ Even with the compression bag, this pillow is significantly larger than inflatable alternatives — it will take up carry-on space.
Pros
- +Very comfortable foam filling
- +Packs down to quarter size
- +Doubles as a camping pillow
Cons
- −Not designed specifically for neck support
- −Largest option when unpacked
Don't buy if
- ⚠ This is a rectangular pillow, not a neck pillow — it works best against windows or as a lumbar pillow, not wrapped around your neck.
- ⚠ Replaces the original Compressible Pillow, which Therm-a-Rest no longer lists. A camp-style rest pillow, not a neck pillow.
