Sleeping Mats Comparisons: Which One Is Right For You?

Not all sleeping mats are created equal — and the difference between a great night's sleep and a cold, uncomfortable one often comes down to which mat you're lying on. Whether you're a weekend camper, a backcountry hiker or planning a serious alpine expedition, choosing the right sleeping mat for your conditions matters more than most people realise. This guide breaks down the key differences between the three brands we trust most — Exped, Sea to Summit and Therm-A-Rest — and helps you work out which sleeping pad for camping is the right fit for you.

If you're new to sleeping mats and want a broader overview of mat types and R-Values before diving into brand comparisons, our sleeping pads for camping guide is the right place to start.

What to look for in a sleeping mat: the key specs

Before comparing brands, it's worth knowing which specifications actually matter when choosing a sleeping pad for camping. Our ultimate sleeping mat guide covers this in detail, but here's a quick summary:

Exped sleeping mats — Swiss-engineered performance across every R-Value

Exped is a Swiss brand with a reputation for engineering some of the most technically capable sleeping mats on the market. What sets them apart is their range depth — from entry-level foam options right through to expedition-grade insulated mats with R-Values above 10 — combined with thoughtful construction details like flat-valve technology and highly durable fabrics that hold up over multi-year backcountry use.

Our Exped collection includes several standout mat options:

Exped Ultra series (3R, 6.5R, 7R, 8R, 10R) — the ultralight end of the Exped range, using a horizontal chamber construction and minimal fabric weight to deliver impressive R-Values in a very compact, lightweight package. The Ultra 6.5R is a strong three-to-four season option; the Ultra 8R and 10R step into true alpine territory. If you're counting grams, start here.

Exped Dura series (6R, 6.5R) — where the Ultra prioritises low weight, the Dura prioritises durability. Heavier-duty fabric construction makes the Dura series a better choice for rough terrain, regular use and anyone who puts their gear through hard conditions. The Dura 6.5R in particular is a favourite among our customers for extended multi-day use, as reflected in our customer reviews.

Exped Flex Mat series (foam) — closed-cell foam mats at various R-Values (1.5R, 3R), available in folding formats that work as standalone mats or as insulation layers under an inflatable. Lightweight, indestructible and a great budget entry point for occasional camping.

Sea to Summit sleeping mats — comfort-focused innovation

Sea to Summit is an Australian brand that has built its sleeping mat range around one central idea: getting more comfort and insulation into a lighter, smaller package than the competition. Their Air Sprung Cell (ASC) technology — which uses thousands of individual air cells rather than horizontal chambers — delivers a noticeably more stable, mattress-like surface that doesn't rock side to side when you move.

Browse our Sea to Summit collection for their full sleeping mat range. Key highlights include:

Ether Light XR Pro Insulated — our current top pick for cold-weather camping, with an ASTM-tested R-Value of 7.4, 10cm Air Sprung Cell thickness and ThermalCore insulation technology. 25% lighter than the previous model. The benchmark for four-season inflatable sleeping mats at this price point.

Comfort Light Insulated — a more accessible price point with a solid R-Value for three-season use. Good for hikers who want the ASC comfort advantage without the premium cost.

Sea to Summit mats are also notable for the XPRESS valve system and integrated Airstream pump sack, which makes inflation and deflation fast and genuinely easy — a small thing that matters at the end of a long day on the trail.

Therm-A-Rest sleeping mats — the industry benchmark

Therm-A-Rest essentially invented the self-inflating sleeping mat in 1972 and has spent five decades refining the category. Their range spans foam, self-inflating and air mats, and the brand is trusted by everyone from casual weekend campers to professional mountaineers operating in extreme cold.

Our Therm-A-Rest collection includes key models across their range:

NeoAir series — Therm-A-Rest's inflatable range, using their Triangular Core Matrix construction for a high warmth-to-weight ratio. The NeoAir XTherm is one of the highest-rated backcountry sleeping mats available, with an R-Value of 7.3 in a remarkably light package.

ProLite series (self-inflating) — a long-standing favourite for three-season use. Self-inflating foam construction gives it reliable warmth without the risk of puncture, making it an excellent choice for campers who prioritise durability and simplicity.

Z-Lite Sol (foam) — the iconic accordion-fold foam mat. Virtually indestructible, extremely lightweight and highly packable as an emergency layer or lightweight camping bed. An excellent complement to an inflatable mat for alpine conditions.
