Buying Guide
Type of mattress
Choose between air beds, self‑inflating foam and closed‑cell foam. Air mattresses are lightweight and pack small but need a pump and are vulnerable to punctures; self‑inflating mats offer a balance of comfort and insulation; closed‑cell foam is cheapest, very durable and best for rough ground.
Insulation and warmth (R‑value)
If you'll use the mattress in cool or changeable UK weather, check insulation or R‑value where provided — higher values retain more heat. Backpackers prioritise low weight with modest R‑values, while car campers and glampers often want thicker mats with better thermal performance.
Durability and weatherproofing
Look for robust outer fabrics, reinforced seams and puncture‑resistant materials, plus waterproof or water‑repellent covers for damp grass and dewy mornings. Also check repair kits, warranty length and whether replacement covers are available from UK retailers.
Comfort, thickness and size
Thickness and surface design determine comfort — thicker mats (6–10 cm or more) feel more like a home mattress and suit longer stays or glamping, while slimmer mats save weight. Make sure the mattress dimensions fit your tent, van or camping cot and consider single, double or king sizes according to your needs.
Portability and ease of use
Consider packed size, weight and how you inflate it — built‑in or electric pumps are convenient for car camping, hand or foot pumps and integrated valves suit camping without mains power. Also factor in how easy it is to dry, fold and store between trips.
Frequently Asked Questions
What is the best mattress for outdoor use in 2026?
There’s no single best mattress — the right choice depends on use. For ultralight backpacking brands like Therm‑a‑Rest and Sea to Summit lead for low weight and good R‑values; for car camping and glamping Outwell, Vango or Exped offer thicker, more comfortable options sold by UK outlets such as Go Outdoors, Cotswold Outdoor and Decathlon.
Is an outdoor mattress worth buying in the UK?
Yes, if you camp more than once or want better sleep than a basic roll mat provides. A good outdoor mattress improves comfort and warmth, reduces back pain and is useful for garden sleepovers, festivals and van trips — it’s a sensible investment if you value sleep quality outdoors.
Which outdoor mattress offers the best value for money?
Value depends on intended use: for occasional car camping, mid‑range air beds from Outwell or Vango give a good balance of comfort and price; for multi‑season use, a self‑inflating mat from Exped or Therm‑a‑Rest offers longer life and better insulation, often representing better value over time.
Therm‑a‑Rest vs Exped — which should I buy?
Therm‑a‑Rest is known for compact, highly insulated air mats (good for cold conditions and backpacking) while Exped focuses on thicker, very comfortable self‑inflating mats ideal for car camping and glamping. Choose Therm‑a‑Rest for low weight and compactness, Exped for comfort and surface area.
Can I use a memory foam mattress outside?
Memory foam is generally not designed for outdoor use unless it’s specifically encased in a weatherproof, breathable cover and used in dry conditions. Standard memory foam will absorb moisture, take a long time to dry and is prone to mildew, so it’s better reserved for indoor use or enclosed vans.
How do I care for an outdoor mattress?
Always dry the mattress fully before packing to avoid mould, store it loosely rolled in a dry place, and repair punctures promptly with supplied kits or manufacturer spares. Clean covers according to instructions, and avoid placing it on sharp stones — use a groundsheet under single‑layer mats.
Where can I buy outdoor mattresses in the UK?
Major suppliers include Go Outdoors, Cotswold Outdoor, Decathlon, Argos and Amazon UK, plus specialist online retailers and brand stores (Therm‑a‑Rest, Outwell, Vango, Exped). Check in‑store for sizing and comfort trials where possible, and look for seasonal sales to get better deals.
What size mattress should I choose for camping?
Pick a size that matches your tent or vehicle and sleeping style: standard single (approx 190 cm) is common for tents, while couples often prefer a double or two singles. Also consider width and whether you want extra length or a wider ‘king’ option for greater comfort.
