Description

🔁 Square Rectangle Split Replacement Mattress Cover – Made to Measure

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.


🧵 Tailored for Square Rectangle Split Geometry

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


❄️ Square/Rectangle Split Mattress Cover Fabrics

Choose the fabric that best suits your comfort and environment 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 busy use

All covers are:

  • Removable

  • Washable

  • Zip-fastened

  • Built for long-lasting performance


🚐 Designed for Leisure & Marine Use

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.


🛏️ When a New Mattress Might Be Better

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.)


🌬️ Damp or Mould Concerns?

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

👉 Add a moisture-reducing mattress spacer (Airmat)
