Therm-a-Rest Compressible Pillow Review

Overview

The Therm-a-Rest Compressible Pillow is a foam camp pillow stuffed with offcuts from the company’s sleeping pad production. It is wrapped in a brushed polyester cover and fitted with a cinch cord that sets firmness. It suits car campers, weekend backpackers and travelers who put sleep ahead of grams. Ultralight hikers will find that the comfort comes at a real cost in weight and pack volume.

Performance

Comfort. This is the pillow’s selling point. CleverHiker’s testers rank it among the most comfortable camp pillows they have used, and their founder kept carrying it on several multi-day backpacking trips despite the weight. The foam chunks give it a soft, sink-in feel closer to a bed pillow than to an inflated air pillow, which some sleepers say feels like a pool toy. The polyester cover is quiet against the skin, with none of the crinkle of coated nylon, and the soft foam doesn’t crush the ear for side sleepers. Back sleepers tend to like it straight out of the bag. Side sleepers usually need to work the cinch to get enough height.

The cinch cord. Pulling the cord bunches the foam into a smaller, taller, firmer mass. Loosening it spreads the fill into a flatter, softer pad. The range is useful, but the tradeoff is coverage. Cinched tight, the pillow loses roughly half its surface area. A sleeper who tosses around may roll off the sweet spot at 2 a.m.

Loft retention. The main complaint is that the foam migrates and compacts overnight. Pieces shift inside the cover and settle under the weight of a head, and the pillow can go flat by morning, especially under side sleepers. A quick shake fixes it. The insulation layer on top smooths out the lumpy feel of the foam chunks, but it doesn’t stop the settling. Reviewers on REI’s site also report that foam fill has been reduced in newer production, and one buyer called a recent unit unusable for lack of foam. Even so, the pillow holds a 4.4-star average across 48 reviews there.

Weight and packed size. CleverHiker lists the claimed weight of the Regular as 10 oz and put one on a kitchen scale at 10.9 oz. That is well over the 1.7 to 6+ oz typical of backpacking air pillows. The pillow folds into its own sleeve and cinches down to about half its expanded size, but it is still a bulky package. Ultralight backpackers and thru-hikers are the group least likely to carry it.

Care and durability. It can go in the washing machine, which few camp pillows allow. The foam pieces hold water like sponges, though, and drying takes a while. Therm-a-Rest advises letting a new pillow sit open for 24 hours to restore loft after shipping, and storing it open and uncinched between trips. The company has used pad-factory scrap this way for years, and owners generally describe the pillow as durable. It is made in the USA.

Choosing a Version

The Small, Large and two middle-weight versions share the same fill, cover and cinch cord. What changes is footprint, loft and weight.

• Small (198 g). The lightest version, at 28 × 38 × 13 cm. It is the only one that makes sense for backpackers who want foam comfort and are willing to carry a few extra ounces over an air pillow. Its short length suits back sleepers and anyone who tucks it into a hood or stuff-sack liner. Larger sleepers will find it low.
• 230 g and 255 g. These sit in the middle of the range, where the 33 × 46 × 15 cm Regular belongs. This is the size most reviewers test and the one CleverHiker uses as its benchmark. It has enough area to stay under the head when tossing and turning, and enough loft for most side sleepers once the cinch is tightened. It is the best choice for weekend backpacking and travel.
• Large (340 g). At 38 × 56 × 18 cm, this is the car-camping and base-camp option. One REI owner who carries both the medium and the large says the large weighs about a pound and still earns its place on comfort alone. It suits fussy side sleepers and broad shoulders. It is also too big to fit inside most sleeping bag hoods.

Pros & Cons

Pros

• Soft, bed-like feel that outclasses most inflatable pillows
• Quiet polyester cover with no crinkle
• Cinch cord adjusts firmness and doubles as the pack-down closure
• Machine washable
• Upcycled foam fill and 60% recycled cover
• No inflating, with no valve to fail
• Lifetime warranty and a reasonable price

Cons

• Heavier and bulkier than any air pillow made for backpackers
• Foam shifts and flattens overnight, especially under side sleepers
• Cinching up for height cuts the usable surface roughly in half
• Foam holds water and dries slowly
• Some buyers report a thinner fill in recent production
• Needs fluffing and open storage to keep its loft

Who Should Buy This

Car campers, van travelers, hut-to-hut hikers and weekend backpackers who care more about sleep than base weight will get the most from it. The Small is the only version worth considering for a multi-day carry, and even then only for hikers whose gear is not trimmed to the gram. Anyone running an ultralight kit, or needing a pillow that holds its height all night without a shake, should buy an inflatable pillow or stuff clothing into a sack.

Verdict

The Compressible Pillow gives the closest thing to a home pillow that fits in a backpack. It is quiet, washable and easy to adjust. The loft drifts, the packed size is large, and the weight rules it out for ultralight kits. Take the Small for short trips, the Regular for general camping, and the Large when the car is parked next to the tent.
