Which mattress made to measure you need
Each category leads to its own configurator. What differs is the cut and the cover, not the workmanship: foam core, fleece wrap and a sewn cover are the same throughout.
Mattresses for caravans and motorhomes
27 shapes for the bed box in your vehicle - rectangular, with a corner cutout, with rounded corners or as a trapezoid.
View categoryHow we build a mattress to size
Nothing sits ready on a shelf. Every mattress starts after your order: cut the foam, wrap it, sew the cover. Which fabric goes on the core is listed on the fabric range page - for outdoor use we take the outdoor fabrics.
Foam core with density RG 35/40
The foam in the core has a density of 35/40, comparable to firmness grade H3. That is furniture quality, not packing foam.
A 0.5 cm thermal fleece wrap
A 0.5 cm fleece layer sits around the foam core. It protects the foam, evens out the edges and lets the cover sit smoothly.
Removable, washable cover
Every cover has a sewn-in zip. It comes off and goes into the machine at 40 °C at most, see care and cleaning for the details.
Your measurements, angled ones too
You set length, width and thickness. Bed boxes in vehicles are rarely rectangular - rounded corners, angled sides and cutouts are sewn in. For unusual shapes a template is enough, the tolerances for customization are described there.
10 to 15 working days
Because every mattress is sewn after the order comes in, production takes 10 to 15 working days depending on the season.
