Outdoor mattresses made to measure at a glance
An outdoor mattress is a mattress for outside spaces, with a cover that withstands sun, showers and dirt. We sew our outdoor mattresses in Westoverledingen to your measurements: foam core, thermal fleece and a removable cover in solution-dyed acrylic. Every model folds together. The difference lies in the fabric, so the range is sorted by collection.
What the cover withstands outdoors
All five fabrics are solution-dyed: the colour sits in the core of the fibre and not on the surface. That is why the colours are UV-resistant, the lightfastness is 7 to 8 out of 8, and the manufacturer gives a 5-year guarantee on colour fastness. All of them are finished to repel water and dirt, PFAS-free. How hard-wearing a cover is, is measured by the Martindale test. All colours and data sheets for each collection: Agora Life, Agora Panama, Agora Lines and Rayure and Agora Simmetria.

Weather-resistant, water-repellent or waterproof?
The three terms are often mixed up. For a mattress that lies outside, it means this: the cover withstands sun, showers and stains, and the foam core inside should stay dry. The guide What does waterproof mean explains the difference between the terms.
Water-repellent
The finish makes raindrops and spilt liquids bead off before they soak in. In the spray test, Agora Panama, Lines, Rayure and Life Liso reach 5 out of 5 points.
The cover is water-repellent, not waterproof
Woven acrylic holds a water column of 180 mm. That is enough for a summer shower, not for continuous rain or standing water. If you are looking for a waterproof outdoor mattress in 90x200, you get a water-repellent cover from us, not a laminated one. What the figure means is explained under What is a water column.
Weather-resistant and waterproof
Neither word is a standard term. By weather-resistant we mean that the cover withstands sun, showers and dirt over many summers. For water resistance the measured values count, so we give the spray test and the water column instead of a label.
The foam core stays drier
The core is foam with a density of RG 40/50, wrapped in 0.5 cm thermal fleece. If water gets through a seam or the weave in heavy rain, the core needs time to dry. More about how a filling is built in the guide What is upholstery filling.
Prevent mould
Mould grows where moisture stays for a long time. Never leave a wet mattress lying covered. How to remove mildew stains is shown in the guide Mould on outdoor textiles.
Patio, balcony, garden, boat and daybed
The outdoor mattress is one of four categories under Mattresses made to measure, all from the same workshop. If you want a patio mattress or a garden mattress, the most important thing is the right size. You set the length, width and thickness, and you choose the thickness between 4 and 20 cm. How to measure the lying surface is shown in the measuring guide for furniture cushions, and what counts as a normal deviation for textiles is described under Tolerances for made-to-measure items.
Patio and balcony
As a floor mattress outdoors it lies directly on decking or tiles, for sunbathing, reading or as a play area for children. Stood on its side against the wall in the evening, the floor underneath dries quickly.
Daybed and pallet furniture
For a daybed, a lounge or home-built pallet furniture, we sew the mattress to the inside dimensions of the frame. You will find matching seat and back cushions under Pallet cushions, and more fabrics under Outdoor fabrics.
Garden and camping
On the lawn or in a tent it brings lying comfort to the ground, and folded together you carry it under your arm. For caravans and motorhomes there are separate cuts under Caravan mattresses.
Boat
On deck and in the cabin every centimetre counts. Send us the measurements or a template of the lying surface through the service centre. Rinse salt and sun cream out with clear water after the trip, before they dry on.
Standard sizes, folding and folded
An outdoor mattress 140 x 200 for the daybed or 90 x 200 as a lounger is sewn just like any special size. The page Folding mattresses describes standard sizes and folding, the page Foldable mattresses describes special sizes for storing. An outdoor mattress cover 140x200 for an existing mattress is best discussed with us, because we sew every cover individually anyway.
Cleaning, drying and winter storage
The cover is easy to care for: clear water and a soft cloth are usually enough. Everything else is in the care instructions for Agora and in the care guide for outdoor cushions.
Removing stains
Wipe off fresh stains with lukewarm water and neutral soap. For stubborn stains and mildew stains, the Agora care instructions allow diluted bleach at a ratio of 1:20, followed by a thorough rinse.
Removing and washing the cover
You take the cover off through the sewn-in zip. Wash it with mild soap at 30 °C at most and let it dry in the open air, not in a tumble dryer.
Drying after rain
After a shower, stand the mattress on its side in an airy place until cover and core are dry. In continuous rain, it is better to bring it under a roof.
Dry storage in winter
Before winter, wash the cover, let everything dry completely and store the mattress folded together in a dry, airy place, such as a cellar or a garden shed. An airtight plastic bag is a poor choice, because moisture collects inside it.
