FROM £109.99
Our Square/Rectangle Split Mattress Cover is designed for mattresses featuring a split section where a square and rectangular footprint meet — a shape commonly used in bespoke sleeping areas to optimise space and comfort.
Standard mattress covers simply won’t accommodate these split profiles, which is why every cover we make is cut and sewn to your exact measurements. The result is a snug, professional fit that restores hygiene and appearance without the need for a full mattress replacement, as long as the internal foam still offers good support.
Each cover is hand-made in the UK and tailored precisely to your supplied dimensions.
Mattresses with split square and rectangular outlines need a custom cover pattern that can:
Match the transition between square and rectangular sections
Maintain structure across angle changes
Wrap cleanly without loose edges or bunching
Fit precisely to width and depth variations
You provide your measurements and we’ll manufacture a custom-fit replacement cover that matches your mattress shape perfectly — no sagging, puckering, or distortion.
Ideal for:
Caravan beds with split square/rectangle profiles
Campervan central or corner sleeping areas
Boat cabins with bespoke mattress layouts
Motorhomes with non-standard mattress footprints
Choose the fabric that best suits your comfort and environment needs:

All covers are:
Removable
Washable
Zip-fastened
Built for long-lasting performance
Caravans, campervans, boats and motorhomes often exhibit limited airflow, humidity and condensation — particularly around uniquely shaped mattresses. A made-to-measure replacement cover improves sleep hygiene and helps protect the underlying foam from environmental strain.
If your existing mattress foam has lost support or comfort, you may prefer 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 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
