Custom Cutaway V-Berth Mattress

Precision Comfort for Cutaway V Berth

If your V-berth mattress has one corner sliced off or the layout’s just a bit awkward — we’ll make sure the mattress isn’t. Our Cutaway V-berth mattresses are made to measure, built to fit snugly into tapered, diagonal or offset berth spaces common on yachts, narrowboats, canal cruisers, and more.

No folding. No trimming. No guesswork. Just a properly cut, one-piece mattress made for your exact layout — with full comfort and no wasted space.


Made to Fit – No Gaps, No Sagging

We know how tricky cutaway berths can be. Whether the curve is on the port or starboard side, the base is offset, or you’ve got a diagonal corner chopped for access, we’ll cut the foam to fit it perfectly — no bodging required.

You can choose between:

  • High-density foam for firm, durable support

  • Memory foam for pressure relief and a softer feel

Ideal for:

  • Angled V-berths on yachts or cruisers

  • Offset cabins with limited floor space

  • Narrowboats with shaped forward berths

  • Liveaboards wanting a mattress that actually fits

All mattresses are cut and finished by hand in the UK. You can provide measurements or send us a paper template for 100% precision.


Covers That Work Hard at Sea

Each mattress can be supplied with a removable, zip-off cover, made to match your custom cutaway shape. Choose from three marine-ready fabrics that are as functional as they are comfortable:

TENCEL™ Botanical Fibre

  • Plant-based, breathable, and moisture-wicking

  • Naturally cool to the touch

  • Gentle on sensitive skin

  • Great for long trips and summer sailing

    Mattress with Tencel Cover
    Tencel natural fibre promote a cooling more comfortable nights sleep

Cooltech™ Quilted Polyester

  • Lightly padded and soft to lie on

  • Helps regulate body temperature

  • Fast-drying and great in humid cabins

  • Our go-to fabric for general-purpose boating

    Cooltech mattress
    Cooltech covers provide exceptional levels of cooling, Helping to wick away moisture resulting in a more restful nights sleep

Easy Clean Fabric

  • Wipeable, washable, and durable

  • Tough enough for everyday use, pets, and kids

  • Breathable and low-maintenance

  • Ideal for boats that get regular action

Whichever you pick, it’ll be cut and sewn to follow your mattress shape exactly — no slippage, no stretching, no flapping corners.

Why Replace a Cutaway V-Berth Mattress?

Let’s be honest — most factory-fitted marine mattresses are poor to begin with, and time doesn’t do them any favours. A mattress that’s sagging, musty, or cut to the wrong shape just doesn’t cut it.

A new Cutaway V-berth mattress gives you a better night’s sleep, a cleaner cabin, and a mattress that won’t slide around or leave you hanging off the edge.
