FROM £69.99
Our Square Rectangle Twin Cutaway replacement mattress cover is designed for mattresses featuring two cutaway sections within a square-rectangle footprint — a layout often used in custom bed spaces where access and comfort are both priorities.
Standard covers won’t conform to these twin cutaway angles, which is why we offer a made-to-measure solution, custom-manufactured from your exact dimensions to ensure a snug, professional fit. This restores hygiene and appearance without the need for a full mattress replacement, provided the internal foam remains supportive.
Each cover is hand-made in the UK and tailored precisely to your supplied measurements.
Mattresses with twin cutaway profiles require a specialised cover pattern that can:
Match two cutaway sections
Wrap around non-standard edges smoothly
Maintain structure without loose fabric
Fit varying widths and depths precisely
By providing accurate measurements, we’ll produce a custom-fit replacement cover that aligns with your mattress shape — no bunching, sagging or distortion.
Perfect for:
Caravan beds with twin cutaway corners
Campervan sleeping areas with tailored designs
Boat cabins with unconventional bed layouts
Motorhomes with non-standard mattress footprints
Choose the fabric that best suits your environment and comfort needs:
CoolTech Cooling Fabric – helps regulate temperature and reduce heat build-up
Tencel™ Mattress Fabric – breathable, moisture-wicking and naturally comfortable
EasyClean Mattress Fabric – wipe-clean, hard-wearing and practical for frequent use
All covers are:
Removable
Washable
Zip-fastened
Built for long-lasting performance
Caravans, campervans, boats and motorhomes often face limited airflow, humidity and condensation — especially around custom mattress shapes. A well-fitting replacement cover improves hygiene and helps protect the foam beneath from environmental strain.
If your current mattress 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 helps:
Improve airflow
Reduce moisture build-up
Prevent future mould and mildew
Extend the life of both foam and cover
