Our Island Shape replacement mattress cover is designed for mattresses with a distinctive “island” footprint — often found in fixed beds that are accessible from both sides and benefit from a more generous sleeping area. These beds are common in many caravan, campervan and marine layouts, and require a specialised cover for a proper fit.
Instead of forcing a standard cover onto an irregular shape, this made-to-measure solution ensures a snug, professional finish that protects your existing foam and revitalises your sleeping setup without the cost of a brand-new mattress.
Every cover is precision cut and sewn in the UK to your exact dimensions for perfect fit and finish.
Island-shaped beds differ from simple rectangles — they often:
Have curved or rounded ends
Are accessible from both sides of the bed
Feature unusual proportions and space requirements
Sit in locations where standard covers won’t fit correctly
These covers are crafted to match your measurements, so you get:
A clean, tailored fit
No excess or loose fabric
Easy zip-on, zip-off convenience
Perfect for:
Caravan island beds
Campervan central beds
Boat and motorhome island sleeping areas
Choose the fabric that suits your environment:
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, durable, and perfect for leisure use
All options are:
Removable
Washable
Zip-fastened
Built for long-lasting use
Island beds in leisure vehicles and boats often face conditions standard bedroom mattresses never see — including limited ventilation, condensation, humidity, and frequent use. A replacement mattress cover that fits properly not only looks better, it helps preserve your underlying foam and enhances sleep hygiene.
If the foam inside your mattress has lost support or cushioning, you may want to consider replacing the foam entirely rather than just the cover.

(This also includes mattresses suitable for boats and marine cabins.)
If the reason for replacing your cover is dampness, condensation, or mould, we strongly recommend adding a moisture-reducing mattress spacer underneath your mattress. This helps:
Improve ventilation
Reduce moisture build-up
Prevent future mould and mildew
Extend the life of your foam and cover
