Made-to-measure replacement cover for Right Hand Front (RHF) D-shaped mattresses, ideal for caravans, campervans, boats and motorhomes. Available in CoolTech, Tencel™ or EasyClean fabrics — all washable, zip-fastened, removable, and hand-made in the UK.
All colour option only apply to EasyClean
FROM £69.99
Our RHF D-Shaped replacement mattress cover is expertly crafted for mattresses featuring a rounded “D” profile on the right hand front side — a distinctive shape often used in custom bed layouts to improve access and comfort.
Standard covers just don’t sit well on these contours, which is why we provide a made-to-measure solution tailored exactly to your measurements. You get a snug, tidy fit that restores cleanliness and appearance without needing a full mattress replacement, as long as your existing foam is still supportive.
Each cover is hand-made in the UK and custom sewn to your precise measurements for a professional finish.
Mattresses with a D-shaped edge require a bespoke pattern so the cover can:
Match the curved D profile
Wrap smoothly around curves
Maintain structure without loose material
Fit variations in depth and width precisely
Provide accurate dimensions and we’ll deliver a custom cover that fits perfectly — no bunching, no sagging, no compromise.
Perfect for:
Caravan sleeping layouts
Campervan bed zones
Boat cabins with D-shaped mattress designs
Motorhome beds with ergonomic profiles
Choose the fabric that suits your environment and comfort needs:
CoolTech Cooling Fabric – helps regulate temperature and reduce heat build-up
Tencel™ Mattress Fabric – breathable, moisture-wicking, naturally comfortable

All covers are:
Removable
Washable
Zip-fastened
Built for long-lasting performance
Caravans, campervans, boats and motorhomes often face higher humidity, limited airflow and condensation — especially around uniquely shaped mattresses. A well-fitting replacement mattress cover improves hygiene and helps protect the foam beneath.
If your internal foam has lost support or comfort, you may want to replace the mattress rather than just the cover.

(Also suitable for boats and other leisure vehicles.)
If you’re replacing the cover due to damp, condensation or mould, we strongly recommend adding a moisture-reducing mattress spacer beneath your mattress. This helps:
Improve airflow
Reduce condensation build-up
Prevent future mould and mildew
Extend the life of both foam and cover
