About 12cm Motorhome Mattresses

12cm motorhome mattresses offer a slim profile solution for vehicles with limited headroom or storage constraints. Standard domestic mattresses rarely fit the irregular shapes and tight dimensions found in motorhome beds. These custom-made mattresses are cut to exact measurements, accommodating curved corners, angled edges, and specific cutouts around wheel arches or storage compartments. The 12cm depth provides adequate comfort whilst maximising precious interior space. Each mattress meets BS 7177 fire safety standards required for motorhome insurance. Made-to-measure construction ensures perfect fit without gaps or overhang that compromise sleep quality and vehicle functionality.

12cm Motorhome Mattress FAQs

Options include high-density reflex foam, memory foam, and pocket sprung constructions. Memory foam provides pressure relief and temperature sensitivity. Reflex foam offers firmer support and better durability. Pocket springs deliver traditional bounce with good ventilation. All foams are BS 7177 certified for fire safety compliance.
Measure length, width, and note any curves or cutouts. Use a flexible tape measure for rounded corners. Mark unusual shapes on paper or cardboard. Include details about hinges, storage access, or wheel arch intrusions. Accurate measurements ensure proper fit without gaps or overhang issues.
Lead times range from 7-14 working days depending on seasonal demand and current production capacity. Custom cutting and fire safety certification add processing time compared to standard sizes. Free UK delivery is included. Rush orders may be available during quieter periods for urgent requirements.
Guarantees up to 10 years are available depending on foam type and construction. Memory foam typically carries 5-7 year guarantees. High-density reflex foam may offer up to 10 years. Guarantee covers manufacturing defects and premature sagging, not normal wear from regular use.
Yes, these mattresses work with most motorhome bed mechanisms including drop-down beds, fold-away systems, and convertible dinettes. The 12cm depth provides flexibility for hinged sections whilst maintaining comfort. Specify bed type when ordering to ensure compatibility with moving parts.
Absolutely. Despite the slimmer profile, quality 12cm mattresses provide adequate support for full-time living. High-density foams and pocket springs maintain comfort over extended periods. The reduced depth doesn't compromise sleep quality when using appropriate foam densities and constructions.
Standard covers include damask, stretch knit, and zip-off removable options. Waterproof and anti-microbial treatments are available for humid motorhome environments. Zip-off covers allow easy washing. Stretch fabrics accommodate irregular shapes better than rigid woven materials for custom-cut mattresses.
