Buying Guide
Material and fill
Choose a fill designed for outdoor use — quick‑dry or draindown foam, closed‑cell foam or synthetic polyester fibre are common. Quick‑dry foams drain water and dry fast, while closed‑cell foams resist water entirely; each affects comfort, weight and longevity.
Cover fabric and weatherproofing
Look for UV‑resistant, mould‑inhibiting fabrics such as Sunbrella or PU‑coated polyester with taped seams and drainage holes. A good cover will resist fading, repel light rain and be easy to clean, though fully waterproof covers may trap moisture underneath if not breathable.
Size, thickness and compatibility
Match the mattress to your patio furniture — daybeds, sunloungers and benches all need different dimensions and tie‑down points. Thickness (typically 30–80mm for cushions, thicker for daybeds) affects comfort and suitability for overnight use.
Durability and maintenance
Consider fade resistance, anti‑mould treatments and robust zips or fastenings; look for warranty information from UK retailers. Removable, machine‑washable covers and replaceable cores extend life and make upkeep easier in Britain’s changeable climate.
Storage, portability and price
Decide how often you’ll leave it outside — lightweight inflatable or roll‑up designs are easy to store, while thicker foam is heavier but more comfortable. Budget between roughly £30 for basic cushions and £150+ for durable, branded outdoor mattresses sold by UK retailers.
Frequently Asked Questions
What is the best mattress for a patio in 2026?
There isn’t a single best model — the top choice in 2026 is typically a quick‑dry/draindown foam mattress with a UV‑resistant, mould‑inhibiting cover (Sunbrella or similar). These combine comfort, drainage and longevity; always check recent reviews from UK retailers like John Lewis, Dunelm, Wayfair or B&Q before buying.
Is a patio mattress worth buying in the UK?
Yes, if you use your outdoor space frequently for lounging or entertaining. Choose water‑resistant materials and store cushions during prolonged wet or winter months to get the best value in Britain’s variable weather.
Which patio mattress offers the best value for money?
Mid‑range quick‑dry foam mattresses with PU‑coated polyester or Sunbrella‑style covers usually offer the best balance of comfort and durability. Expect to pay roughly £50–£150 depending on size and brand; look out for sales at Dunelm, Wayfair, Argos and John Lewis for savings.
Inflatable vs foam patio mattress — which should I buy?
Choose quick‑dry or closed‑cell foam if you want comfort and long‑term outdoor use; they drain and retain shape. Inflatable mattresses are lightweight and portable for occasional use but can puncture and are less comfortable long term.
Sunbrella covers vs generic polyester — which is better?
Sunbrella and other performance fabrics usually cost more but offer superior UV resistance, colourfastness and mildew protection. Generic polyester covers can be fine for budget purchases but often fade or degrade faster in direct sunlight.
How thick should a patio mattress be?
For regular daybed or lounger use choose 50–80mm for comfort; bench cushions or slim chaise pads can be 30–50mm. Thicker mattresses are better for occasional overnight stays but may be heavier and harder to store.
Can I leave a patio mattress outside all year?
It’s not recommended — even weatherproof materials suffer from prolonged wet, frost and UV exposure. Keep a waterproof cover for short spells of bad weather and store the mattress indoors or in a dry shed during winter to extend its life.
How do I clean and maintain an outdoor mattress?
Remove and wash covers where possible, spot‑clean stains promptly and air the foam core to prevent mould. Use a soft brush and mild detergent for covers, dry thoroughly in shade and consider treating fabrics with a waterproofing spray annually.
