A self-inflating sleeping mat is one of the most important bits of kit you can buy for camping or caravanning — it’s what stands between you and a cold, sleepless night. The right mat gives you insulation from the ground, cushioning for comfort, and a reliable night’s sleep whether you’re in a tent, awning, or caravan. At Newquay Camping Shop, we stock self-inflating mats from Vango, Outwell, and Outdoor Revolution, available online with UK-wide delivery and in our Cornwall showroom.
Self-Inflating vs Inflatable Mats: What’s the Difference?
Self-inflating mats use open-cell foam inside an airtight shell. Open the valve and the foam expands, drawing air in automatically — a few extra breaths firms it up to your preference. They offer excellent insulation because the foam retains warmth even when compressed, and they’re more puncture-resistant than air-only mats.
Inflatable mats (air pads) use chambers of air with no internal foam. They pack smaller and can be lighter, but offer less insulation unless they have additional insulation layers (down or synthetic fill).
For most campers and caravanners, a self-inflating mat is the more practical all-rounder — better insulation, easier setup, and more forgiving if slightly punctured.
Key Specs to Understand
R-Value (Thermal Resistance)
R-value measures how well a mat insulates you from the ground. The higher the R-value, the warmer the mat. Ground is a significant source of heat loss — a mat’s R-value matters as much as your sleeping bag rating.
- R1–2: Warm-weather/summer camping only (above 10°C)
- R2–3: Three-season camping (spring to autumn in the UK)
- R3–5: All-season — suitable for UK winter camping and cold-ground caravanning
- R5+: Expedition/extreme cold use
For Cornwall and South West camping, an R-value of 2.5–4 covers most of the year comfortably.
Thickness
Thickness directly affects comfort — thicker mats cushion pressure points better for side sleepers. Standard mats run 3–5cm; premium mats 7–8cm. Thicker mats also tend to have higher R-values.
- 3–4cm: Lightweight, good for backpackers and solo use
- 5cm: Good all-round comfort for regular campers
- 7–8cm: Closest to a home mattress feel — ideal for couples, families, or longer stays
Size
Mats come in Regular (typically 183 x 51cm), Large (196–200 x 65cm), and Double (183–200 x 130cm) sizes. For caravan awnings and larger tents, a double mat or two large singles is worth considering.

Which Mat is Right for You?
- Summer camping, light and compact: A 3–5cm self-inflating mat with R2–3 rating is plenty for UK summer use in a tent or awning.
- Three-season or autumn camping in Cornwall: Go for 5cm+ and R3 or above — ground temperatures drop quickly in autumn even in the South West.
- Caravan awning or extended stays: Choose a double mat or two large singles at 7cm+ for proper comfort over multiple nights.
- Winter camping or cold ground: Prioritise R-value of 4+ over thickness — insulation matters more than cushioning in cold conditions.
- Side sleepers: Prioritise thickness (7cm+) for pressure-point relief regardless of season.
Self-Inflating Mat Tips
- Open the valve early: Let the mat self-inflate for 10–20 minutes before topping up with breath — rushing the inflation reduces lifespan.
- Store it open and unrolled: Storing rolled and compressed for long periods compresses the foam permanently. Store flat or loosely rolled with the valve open between trips.
- Use a groundsheet: Even inside a tent or awning, a groundsheet under your mat protects against abrasion and moisture wicking.
- Pair with the right sleeping bag: Your mat’s R-value and your sleeping bag’s comfort rating should be matched to the same conditions — a warm bag on a cold-ground mat won’t keep you warm.

Frequently Asked Questions
What R-value do I need for UK camping?
For summer camping (June–August) in Cornwall and the South West, R2–3 is sufficient. For spring, autumn, and any camping where ground temperatures may be low, aim for R3–4. Winter camping or cold-ground caravan awning use warrants R4+.
How thick should a self-inflating mat be?
3–4cm is adequate for backpackers and light summer use. 5cm is a comfortable all-rounder. 7–8cm provides the closest feel to a home bed and is the best choice for families, couples, and longer stays.
Can I use a self-inflating mat in a caravan awning?
Yes — self-inflating mats work well in caravan and motorhome awnings. Choose a mat wide enough for your sleeping space and prioritise R-value, as awning groundsheets are typically uninsulated.
How do I repair a self-inflating mat puncture?
Most self-inflating mats can be repaired with a standard repair kit (a patch and adhesive). Inflate the mat, submerge it in water, and look for bubbles to locate the puncture. Dry thoroughly before applying the patch and allow 24 hours to cure before use.
Can I buy self-inflating mats in Cornwall?
Yes — Newquay Camping Shop stocks Vango, Outwell, and Outdoor Revolution self-inflating mats at 4 Bamber House, Victoria, PL26 8LQ (Monday to Friday) and online with UK-wide delivery.
