Bespoke Boat & Marine Mattresses

Custom Comfort for Yachts, Motorboats, Narrowboats & More

Your boat isn’t standard — your mattress shouldn’t be either. We make bespoke boat mattresses cut to your exact shape and size, so you can sleep properly even in the trickiest of berths. Whether you’re fitting out a forepeak, V-berth, curved bow, or an awkward bunk in a narrowboat, we cut to order and build to last.

You can choose from 16 mattress shapes on our site. If your layout’s a bit different — and let’s face it, most are — just pick the closest match and send us a drawing or paper template. We’ll cut your mattress to fit clean and tight. No trimming, no guesswork, no half-measures.


Made to Measure for Every Kind of Boat

From inland canal cruisers to coastal yachts, we supply custom boat mattresses for:

  • Yachts & sailing boats

  • Motorboats & cabin cruisers

  • Narrowboats & canal boats

  • Houseboats & liveaboards

  • Catamarans

  • Cabin bed conversions & V-berths

  • Saloon bunks, split beds & corner setups

We also cut replacement marine mattresses for second-hand boats, tired factory foam, or bedding that’s gone soft, mouldy, or lost its shape.


Three High-Performance Fabric Options

All of our made-to-measure mattresses come with the option of a removable, zip-off cover, made to handle real life on the water. Choose from three fabric types, depending on how you use your boat.

TENCEL™ Natural Fibre

  • Breathable and plant-based

  • Naturally cooling and moisture-wicking

  • Soft on skin and hypoallergenic

  • Great for enclosed cabins or year-round use

Cooltech™ Quilted Polyester

  • Lightly padded and soft to the touch

  • Wicks moisture and promotes airflow

  • Helps regulate temperature

  • Ideal for warm-weather sailing or stuffy berths

Easy Clean Fabric

  • Wipeable, washable and stain-resistant

  • Handles daily wear from pets, kids and heavy use

  • Keeps things fresh with minimal effort

  • Perfect for busy boats or second-hand refits

All covers are made to fit your custom mattress shape — no saggy corners, no shifting.


Why Replacing an Old Boat Mattress Matters

Boats and moisture go hand in hand. Over time, marine mattresses soak up damp, sweat, salt and everything else that comes with life onboard. And let’s be honest — if you’ve bought a second-hand boat, that old foam has had someone else’s back on it for years.

A fresh, custom-cut marine-grade mattress isn’t just more comfortable — it’s a smarter, healthier choice. Our foams are breathable, long-lasting, and built to stay firm where you need support. Better sleep, better hygiene, better sailing.


We Also Make Custom Boat Cushion Covers

Need more than a mattress? We also cut and stitch replacement cushion covers for both the cabin and outdoor seating. Whether it’s cockpit cushions, saloon benches, or bunks that need freshening up, we’ve got you covered.

Just send your old covers or a drawing, and we’ll make new ones to match — using the same three fabric options.
