Made-to-measure replacement cover for Right Hand Front (RHF) square-rectangle mattresses with a rounded corner, perfect 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 Square Rectangle Rounded Corner replacement mattress cover is designed specifically for mattresses that combine a rectangular profile with a rounded right front corner — a common shape in bespoke sleeping areas where comfort and ease of access are essential.
Standard covers won’t sit snugly on these profiles, which is why we manufacture each cover to your exact measurements. The result is a tailored, professional fit that restores appearance and hygiene without the need for a full mattress replacement when the internal foam is still supportive.
Each cover is hand-made in the UK and crafted to your individual measurements for a clean, precise finish.
Mattresses with a square/rectangle layout and a rounded corner require a bespoke pattern so the cover can:
Fit the rounded corner profile
Wrap smoothly without loose edges
Maintain structure across both square and curved areas
Match variations in depth and width precisely
You supply the measurements and we’ll deliver a custom replacement cover that fits perfectly — no bunching, sagging, or distortion.
Perfect for:
Caravan beds with rounded rectangle profiles
Campervan sleeping areas with softened corners
Boat cabins with ergonomic mattress shapes
Motorhomes with custom bed layouts
Choose the fabric that best suits your environment and comfort preference:

Zip-fastened
Manufactured for long-lasting performance
Caravans, campervans, boats and motorhomes often face higher humidity, limited airflow and condensation — especially with uniquely shaped beds. A well-fitting replacement mattress cover enhances hygiene and helps protect the underlying foam from environmental strain.
If your internal foam has lost support or cushioning, you may prefer replacing the mattress rather than just the cover.

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