About Built-In Bed Mattresses

Built-in bed mattresses are custom-made mattresses designed for fixed bed frames in caravans, motorhomes, boats, and specialist furniture. These beds often have unusual shapes, cut-out corners, or non-standard dimensions that standard rectangular mattresses cannot accommodate properly. Standard high street mattresses leave gaps around curved corners, wheel arch cut-outs, or awkward angles. Made-to-measure mattresses are cut to exact specifications, ensuring a perfect fit. Each mattress includes BS 7177 fire safety certification required for caravan and motorhome insurance. Custom cutting typically takes 7-14 working days depending on seasonal demand.

Built-In Bed Mattress FAQs

Built-in bed mattresses can be cut to any shape including curved corners, angled cuts, wheel arch cut-outs, and irregular dimensions. The manufacturing process uses templates or precise measurements to ensure accurate cutting. Common shapes include rounded corners for caravan beds, notched corners for furniture, and tapered ends for boat berths.
Built-in bed mattress delivery typically takes 7-14 working days from order confirmation. Production time varies with seasonal demand, particularly during spring when caravan preparation increases. Rush orders may be available during quieter periods. Free UK delivery is standard, with the mattress arriving vacuum-packed for easier handling through narrow doorways.
Built-in bed mattresses come with guarantees up to 10 years depending on the foam type and construction. Memory foam and pocket sprung versions typically offer longer guarantee periods. The guarantee covers manufacturing defects and premature sagging. BS 7177 fire certification is included as standard for insurance compliance.
Built-in bed mattresses are available in reflex foam, memory foam, latex, and pocket sprung constructions. Memory foam offers pressure relief and body contouring. Reflex foam provides firmer support and better ventilation. Latex gives natural bounce and temperature regulation. Thickness ranges from 4 inches to 8 inches depending on bed base clearance.
Measure the bed base rather than any existing mattress. Use a tape measure for length, width, and note any corners that need cutting. For curved corners, create a cardboard template or provide radius measurements. Photograph unusual shapes from above. Include any cut-outs for wheel arches or furniture legs with precise positioning measurements.
Built-in bed mattresses cannot be returned due to their custom nature, so accurate measuring is essential. Double-check all measurements before ordering. Most manufacturers offer guidance on measuring techniques. If unsure about complex shapes, consider making a cardboard template first to test the fit before ordering the mattress.
Built-in bed mattresses cost more than equivalent standard sizes due to custom cutting and individual production. Prices vary based on size, shape complexity, and foam type. However, the perfect fit eliminates gaps and movement issues common with standard mattresses in non-standard bed frames, making them worthwhile for permanent installations.
